Installing a trunk limit switch on a Lada Granta liftback

I bought Jp Group

(art. 1196500300) 3 pcs.
The surprise was that they came without connectors
(without “males”).
But with rubber caps. ) I started looking for a suitable connector. It turned out that such a connector is sold separately, and it costs a hefty 100 rubles per piece! Moreover, a domestic trailer for it costs 50 (!) rubles. True, without a rubber cap. It seemed to me that the amount was too high (a question of principle, not a monetary one), and I decided to join the collective farm. I picked it up in stores, to no avail. I went online. I came across on the Renoshek website that they select a connector from the crankshaft sensor from TAZs and it costs about 50 rubles. I found it, bought it... as always, the stingy one pays twice, in one store there were only 2 of them, in another it already cost 70. It’s not enough to buy them; you also need to secure them properly on the end switch itself. He hangs out in it a little more. And to do this, I cut around the plastic with wire cutters, fitted the connector, caulked it with the remaining rubber from the connector (I stuck pieces of elastic between mom and dad) and securely wrapped the joint with electrical tape so that it wouldn’t come off. In general, I made a connector. Now I’m writing the text and thinking - why didn’t I immediately buy 100 ruble connectors?
)) Although, in fact, if I had immediately bought these connectors from the crankshaft, without picking them up in stores, without traveling to other stores, then it wouldn’t be a big deal, and the profit would be more obvious.

Next, it was necessary to install them in their standard places (remove the rubber plugs in the sills) and connect in parallel to the driver’s. The limit switch is “normally closed”, i.e. when the door is open there is a circuit, when it is closed the circuit opens. Therefore, the connection is parallel (before this I figured it out myself, checked it with a tester, because I couldn’t find any information on how to connect). The most difficult thing in this process, as always, is working with the casing, more precisely with the plastic of the central tunnel, which is difficult to remove and even more difficult to install. I suffered especially for a long time trying to tighten the last screw - it didn’t fit into the hole and that’s it, I fiddled for about 30 minutes. And the hole there is stupid in the iron, made with a self-tapping screw.

I connected one limit switch trially and checked the operating procedure on the interior lamp. Turned on the DOOR lighting mode and let's open and close the doors with the limit switch connected. Everything works correctly. Well, in this way I installed and stretched the wires from the other end switches. I ran the wires under the upholstery near the back sofa, near the vertical wall, where no pressure would be exerted on the wire.

Connected. I checked. Everything is working. Now at least I’ll know if which door is not completely closed... when driving, I’ll see it on the panel, and when arming, the alarm will give a signal) Well, the perimeter is now protected))

I also timed the installation of thresholds purchased for another 2 months to coincide with this event. back, because I knew that I would install limit switches so as not to climb twice).

PS: from the photo you can see that I have belts with pretensioners - great! (I didn’t think about this when purchasing, I only knew that there were 2 pillows).

The Lada Granta Liftback car in the “Standard” configuration is equipped with only one limit switch at the driver’s door. The remaining three doors have built-in rubber plugs.

The “Norma” configuration has a similar arrangement, but the owner can additionally install limit switches on the Grant Liftback independently. To do this, first remove the decorative inserts on the thresholds. Only the “Lux” configuration provides a full set of functional limit switches for four doors.

Review of Manufacturer Prices

*prices are current as of 10/09/18.

The opinions of the service station masters agreed on the choice of manufacturer - there is not much difference. When purchasing original products, the service life of the equipment exceeds 5 years.

Oxygen sensor to Priora converter

Installation in “makeshift” conditions and poor-quality manufacturing only shorten the period of use of the equipment. Often the owner is to blame for the breakdown, violating the vehicle maintenance regulations.

Reviews

Conclusion Limit switches on a car should always be in good working order. Provided proper maintenance and lubrication, the service life is at least two years. It is necessary to regularly analyze the condition of the limit switches in order to notice and prevent malfunctions in time. You should also adhere to the operating instructions.

Installation of limit switches on Lada Granta

An activation sensor in all doors will provide additional comfort. To carry out the installation procedure, you will need special equipment and available materials: lubricant, rubber tips, screwdriver, rag.

Step-by-step algorithm of actions:

1. Remove the rubber tip.
2. Open the housing and remove the limit switch.
3. Remove the block with wires and disconnect.
4. Install a new sensor.
5. Reassemble.

After the basic steps, you need to check the functionality of the device. To connect the limit switch to the power circuit, you will need to connect two terminals: first “+” and then “-”.

Preparatory stage

• impact screwdriver;
• cross bits;
• pliers;
• plastic clips in case of damage to the standard ones;
• liquid for removing rust and corrosion;
• a new lock, the modification is chosen individually by the owner.

Procedure for independently replacing the driver's door lock on a Lada Granta Liftback

1. We install the car within the perimeter of the repair area and provide unobstructed access around the perimeter.
2. We take priority safety measures when carrying out work. We fix the rear row of wheels with wheel chocks and engage first gear to avoid arbitrary movement.
3. Open the driver's door, use an impact screwdriver to unscrew the two screws securing the shackle to the car body, and remove it from its seat. We install a new shackle with soundproofing material.
4. Let's start removing the constipation: unscrew the plastic float and remove the stem.
5. We unscrew the car door card, two screws, eight plastic clips around the perimeter.
6. We disconnect the block with wires from the double-glazed window control unit, speakers, and central locking.
7. From the outside, unscrew the three screws that secure the lock body to the door.
8. We remove the two rods, having first disconnected them with pliers.
9. We carry out preventive maintenance, clean the seat, remove old grease, and apply a thin layer of new one.
10. Let's start installing the new lock.
11. We assemble the structure in the reverse order, unless there are other breakdowns that require surgical intervention or elimination.

During the installation process, we pay attention to the integrity of the electrical wiring, insulating layer, terminals, and blocks with wires. If there are signs of wear, replace them with new ones.

Do not operate the machine with faulty electrical wiring.

Typical door lock malfunctions

• tightness of locking the door;
• increased noise when opening/closing;
• the central lock does not lock the door and does not respond to signals;
• unlocking is accompanied by a creaking, metallic grinding sound;
• While driving, the door vibrates, cracks are visible in the places of contact with the standard seal.

Common Causes of Premature Wear

• failure to comply with the deadlines for technical inspection, preventative maintenance, lubrication, and replacement of worn elements;
• third-party mechanical damage resulting in deformation of the door or lock;
• manufacturing defects at the factory;
• the lock has become loose due to loosening of the fastening;
• violation of the adjustment algorithm;
• human factor: systematically locking the door with force.

The defect is eliminated by replacing the constipation assembly.

Replacing the rear (passenger) door lock

The procedure for preventing locking of the front/rear passenger door is carried out by analogy. The design and method of fixation are typical.

Installing a trunk lock on Lada Granta Liftback

1. We place the car on a level platform and provide access to the trunk lid.
2. We take safety measures when carrying out work.
3. We unscrew two screws and remove part of the lower plastic trim of the trunk lid.
4. Unscrew the two screws securing the lock body to the trunk lid;
5. Using pliers, remove the rod from the button to the body.
6. We remove the constipation, carry out preventive maintenance, lubricate the threads and the rod end.
7. We install a new lock and assemble the structure in the reverse order.
8. We unscrew two screws, remove the standard shackle, install a new one with sound-insulating material.

Replacing the hood lock

1. Inside the car, under the dashboard, there is a hood release lever. We pull it towards ourselves.
2. Release the latch and lift the hood.
3. Using a TORX key set to “10”, unscrew the two screws holding the lock body to the body.
4. Using pliers, remove the cable eye from the seat.
5. We remove the lock, install a new one in its place, and assemble the structure again.
6. Lubricate the bow-clamp with silicone grease/solid oil.

Design solution to the problem

Experts recommend going with the first option. Installing a button in the door sill is used on all cars of this class. This path is easier and faster to follow. The driver will only restore the originally designed circuit for connecting the limit switches. With this choice, there is no need to disassemble the locking mechanism. The owner will not have to wander around looking for additional plugs, wires, and insulating materials. He only purchases standard switches for the Lada Granta. Let's look at the most labor-intensive configuration for remodeling - the standard one.

1. Open the car hood. Loosen the bolted connections with an open-end wrench. First unscrew the negative terminal, and then the positive one. Carefully disconnect the wires from the battery so as not to accidentally short-circuit the power source.
2. Remove the limit switch from the hole. To do this, you need to grab the protruding cap. Pull out the switch, overcoming the resistance of the fixing whiskers.
3. Connect two wires to the outermost (used) contacts of the plug.
4. Remove the plug from the rear door mounting hole.
5. Stretch two wires from the driver's door limit switch to the threshold to the installation site. Bring the ends out through the hole, 10 cm each.
6. Strip the wires and connect them to the connector of the new device.
7. Set the interior lighting switch to the operating position.
8. By analogy, the keys located in the openings of the remaining doors of the Lada Grant are changed.
9. The driver's door button is put back last.

When installing each pair of contacts, it is advisable to check their functionality. Measure the circuit resistance with a tester by alternately pressing and releasing the spherical protrusion.

What is important to know about silent locks on the Lada Granta Liftback

Not all car owners are satisfied with the ease and noise level when closing the doors of their car. The defect is caused by excessive wear of parts and design flaws at the manufacturer level.

The principle of noise suppression is implemented by an installed noise absorber. In Lada Granta Liftback models, this is a rubber insert or a plastic polymer.

Silent locks are structurally composed of a pin and a shackle with a noise-absorbing insert. Some car owners practice replacing the arms, while leaving the standard locks unchanged. Already in this case, the noise level will be significantly lower, and locking the door will be easier.

At the same time, systematic use of the door lock leads to rapid wear of the polymer/rubber material. The owner has to come back for preventative maintenance again and again.

Trunk limit for Lada Granta sedan

upd May 2022:
the standard limit switch turned out to be working, returned the factory circuit.
The reason was in the hood switch - it didn’t open when the hood was closed (I bent it back and everything worked normally). Now I installed a reed switch separately for the backlight instead of a mikrik on the trunk door lock.

I was surprised that the liftback trunk light only works in the dimensions mode. And I discovered that the trunk lock switch was faulty - it was constantly closed. Therefore, the standard alarm system did not work correctly, and in addition to this, the hood switch did not press, so I had to bend the bracket. The hood and trunk ends are on the same line, i.e. This is one signal control zone. I didn’t want to deal with the warranty, so I placed my microphone next to the lock’s shackle. The contact of the standard limit switch was disconnected in the block of the 5th door. I ran +12V power from the fuse box so that the light would always turn on when the trunk was opened. At the same time I installed LED strips on both sides.

The last photo shows a standard electric trunk lock. 2191-6305010-10

The Lada Granta Liftback car in the “Standard” configuration is equipped with only one limit switch at the driver’s door. The remaining three doors have built-in rubber plugs.

The “Norma” configuration has a similar arrangement, but the owner can additionally install limit switches on the Grant Liftback independently. To do this, first remove the decorative inserts on the thresholds. Only the “Lux” configuration provides a full set of functional limit switches for four doors.

The operating principle is as follows:

• when the driver's door is activated, the limit switch contacts open, the indicator on the dashboard lights up, and the interior lighting turns on;
• When the remaining three doors are activated, only the interior lamp lights up.

Finalization of the scheme

Work on modifying the door end elements can be delegated to service station specialists. In this case, the owner will be charged an installation fee. You can do everything yourself, then installing limit switches will require plumbing tools and a device for checking the electrical circuit:

1. Tester.
2. Soldering iron.
3. Phillips screwdriver.
4. The wire.
5. Solder POS-40.
6. Corrugated hose.
7. Insulating tape.
8. Limit switch.

The owner must decide on a further plan of action based on the features of the layout of his Lada Granta car. It can activate the button in the threshold or the door lock contacts.

Both options involve parallel connection of unused elements to the working terminals of the door on the driver's side. The switches for opening the doorway of a Lada car are powered using a two-wire circuit. To simplify the choice, we will consider both options.

How to install an electric lock in the trunk lid of a Lada Granta

Electric trunk lock - improving the operation of the Lada Granta

The middle of 2011 is very important in the history of the domestic automotive industry. It was this period that Russian car enthusiasts remembered for the release of a new product from the Volga Automobile Plant - the Lada Granta sedan.

This car successfully fulfilled its purpose, namely replacing the classics of the Samara family.

Created on the basis of the Lada Kalina, Granta today enjoys enormous success among buyers not only in Russia, but also far beyond the borders of our state.

1 What Lada Granta owners missed

Today the car is produced in 3 main trim levels: “standard”, “norm” and “luxury”.

If with the second and third options everything is more or less clear (as they say, we will do everything for your money), then owners of cars with the first configuration were missing such an important detail as the electric drive of the trunk lid and hood lock. At first glance, it seems that such a trifle cannot significantly spoil the mood of a happy car owner

However, given the weather conditions in our country in winter, installing an electric lock for the hood or trunk lid on this car is literally asking

At first glance, it seems that such a trifle cannot significantly spoil the mood of the happy car owner. However, given the weather conditions in our country in winter, installing an electric lock for the hood or trunk lid on this car is literally asking for it.

Judge for yourself, because in 20-degree frosts, the problem of opening the trunk lid and hood becomes the main headache of the car owner: either the key cannot be inserted into the core of the lock, or it can only be pulled out with great effort. One way or another, a lock with an electric drive is needed, and it is very difficult to argue with this fact.

This is evidenced by the presence of wiring for the electric drive, as well as a special button on the key fob.

If you press and hold this button for two seconds, you can hear a click in the electrical package control unit.

2 Installing an electric lock on a Lada Granta

The entire process of installing an electric lock can be considered in the form of a simple algorithm. First, remove the inner trunk trim. To do this, disconnect the 7 pistons and 2 bolts holding the trunk closing handle.

Next we notice the lock mechanism. Insert the key into the lock and turn it in different directions. With this action it will be easier for us to understand the principle of operation of the lock in its various positions.

In the “closed” position, the pusher in the lock moves in vain, and in the “open” position, it presses on the rod, due to which the trunk or hood lids open.

After determining the principle of operation of the lid lock, it is easy to guess that if you connect the pusher to the activator, then the need to insert the key into the lock will disappear on its own.

The size of the first should correspond to the size of the protrusion on the pusher. We will insert the activator rod into the second hole. The first hole in the part should be in the center, the second - in the lower left edge.

In addition to the part with the holes, we will need a thin washer that can be inserted into the hole in the center.

Then we assemble the entire mechanism: our part is put on the plastic pusher. We put a new washer on top. In order to fasten this structure, you can use a retaining ring. We attach the activator to its place provided by the Lada Granta manufacturing plant. Using special rods that were included with the activator, we connect the latter with the part we turned.

Adjusting the trunk lid of Lada Granta

Tools:

• Ratchet wrench
• 10 mm head

Note:

Check the gaps between the body and the trunk lid; they should be the same throughout. If necessary, adjust the position of the trunk lid of the VAZ 2190.

1. Open the trunk.

2. Loosen the trunk lid and adjust the position of the lid.

Note:

Carefully close the trunk lid and, moving it, adjust its position in the opening. The gaps between the rear fenders and the trunk lid should be uniform and identical. Then finally tighten the trunk nuts.

3. If necessary, adjust (with the trunk lock locked) the height position of the lid relative to the rear wings by rotating the two rubber stops in the desired direction.

Electric trunk lock Granta liftback installation

For work we will need:

1. Liftback)) 2. Opening button with connector or 2 female wires. 3. Electric drive (installed StarLine SL-2). 4. Cable (approximately 30 cm) and 2 clamps. 5. Electrical tape, wire cutters, wires, flat and Phillips screwdrivers, 8 and 7 wrench.

To install the drive, you need to get rid of the lock rod, probably many people know, it is firmly in place and will not allow the drive to open the lock until you insert the key into the lock, so we install a cable instead, this way you can open the trunk from the outside.

Disassembling the trunk door

We pull off the central plastic (2 pistons and on the edges of the latch)

Unscrew the 2 opened screws and pull them off (on two pistons)

A pair of screws have opened again, unscrew them

We will pull off the main casing from these corners, and before that we unscrew the 2 bolts in the front handles

The trim comes off very easily and this is what's underneath

And here is the thrust of the lock (from the cylinder to the lock itself), we will get rid of it.

The drive we will implement

We select a place for it, I found it here, we make notches for the holes

Pulling off the traction from the larva

We drill holes for the self-tapping screws, put the drive together with our rod inward and just attach it to our place to determine the length of the rod. We hooked up the drive, pulled it out to its full length and the door lock should be open. On the top of the lock there is a ring that you need to pull to open it (it will be clear later in the photo), we bring the rod to the ring and make a notch with wire cutters.

Now we take everything out, the electric drive and the lock itself, by unscrewing 2 bolts with a 8 key. We pull out the right corner of the lock and unhook the second end of the rod, then completely pull out the lock and remove the connector.

Here is the drive rod with a notch, at a distance of 2 cm from the notch we chop off the excess tail with a chisel

Along the notch we bend the rod into the letter “G” and insert it into the lock

Connecting the signaling to the central locking system

Now we get to the most interesting part. The contacts of the signaling relay must be connected to the gap in the brown wire (see diagram in Chapter 1). Moreover, this will be required regardless of the configuration. Oddly enough, we won’t need power cables at all. And the task now looks like this: you need a two-wire signal cable connected to the break in the brown cord.

The moral here is:

1. If you were able to remove the central lock control unit, connect the cable to the break in the wire connected to pin “7” of the control unit;
2. If you have removed the door trim, then pull the cable out of it (from the point where the brown cord breaks).

It is clear that the second side of the cable must reach the relay connector of your alarm.

Option for the “Lux” package

So, this means that there is a button on the armrest in the cabin that allows you to lock the locks. From one of the contacts of the button, to which a “plus” is applied when pressed, you need to stretch the cord to the signaling unit. Nothing else is required, and you can connect the alarm according to the following scheme:

According to reviews, this option is suitable if we are talking specifically about the “luxury” configuration. By the way, the resistor can be connected to the gap in the wire designated “blue” (the common contacts are then connected with a jumper).

It must be remembered that when working with any electrical equipment, you must first remove the negative terminal from the battery.

Each cord that is re-laid must not touch metal surfaces. Otherwise, in places of contact, the wire is protected with a tube that can withstand temperatures of 250 degrees. This is how you can protect yourself from unforeseen consequences.

Troubleshooting

Drivers may encounter various types of malfunctions. Even though the sensor is protected, it is not as reliable as the manufacturers claim. In addition to silicone lubricant, other measures can be used:

1. Install the spring under the rubber cover. If this element is elastic, it will protect the mechanism even at very low temperatures.
2. Remove the protective caps for the winter, but there is a danger that the element will quickly become clogged with dust and dirt.
3. Treat with protective liquid.

Often drivers replace their original limit switch with a part from another manufacturer or install a boot. In this case, the body of the new element is inserted into the standard connector and secured with a self-tapping screw.

How to extend service life

Craftsmen are constantly coming up with new ways to extend the service life of factory elements. Some people put coins under the rubber band, fasten the parts with tape, or insert washers. To prevent the switch from freezing or becoming deformed, there are several effective techniques to consider:

1. Spring insert.
2. Replacing standard caps with elements from foreign manufacturers.
3. Silicone Grease.

You should not assume that these actions will grant immortality to the limit switch, but these measures will significantly increase its service life.

What are the characteristics of the trunk?

What is the actual volume in liters? If you fold the rear row of seats, the Granta's trunk volume will reach 770 liters, and in the standard position of the rear passenger row, the trunk volume will be 440 liters. This model is the first ever liftback among the entire AvtoVAZ family. In terms of luggage compartment capacity in its standard state, the Granta managed to outstrip such a popular European hatchback as the Volkswagen Golf. However, with the rear row seats folded, the Golf takes the lead thanks to the trunk volume of 1200 liters, which turned out to be unattainable for the Lada designers. After all, the primary goal was to maintain a single wheelbase and platform similar to a sedan.

So, what is the real opinion of Granta owners about the capacity and ease of use of the luggage section, because its volume in liters is quite impressive. The Internet is replete with an incredible variety of photographs posted by the owners. Sometimes the Lada Granta liftback can plunge you into amazement - how much useful luggage its luggage compartment is ready to accommodate. However, in reality, not everything becomes as rosy with the amount of space in the trunk as it is positioned in advertising.

The rear seats have the only ability to fold completely when the front seats are moved close to the instrument panel. The inconvenience is that the rear headrest requires preliminary dismantling before folding. The top shelf in the luggage compartment can be removed without any extra effort, which is very convenient when transporting large items. Due to this action, space will not be added, but the luggage will not rest against anything. Niches on the right and left sides are suitable for storing medium-sized bags or a set of essential tools in case of an unexpected breakdown.

Above these technological recesses there are hangers designed for bags, which eliminates the need to clutter the rear seats with them. There is a light above the left niche, but it turns on when the low beam of the head optics is activated. An excellent solution for cloudy weather or dark periods of the day, however, the inconvenience is that you may forget to turn on the headlights beforehand.

Under the luggage mat you can find a full-fledged spare wheel, to which the manufacturer has added traditional attributes: a jack and a wheel wrench. There is enough space in the niche to accommodate a spare wheel with a large radius (if you wish to install 16-inch wheels). There is still room for the tool. This is easy to verify, you just have to look at the photo.

The wipers do not adhere well to the glass

The luggage compartment mat in the LADA Granta liftback made of rubber has not become popular among owners. The quality of the material is a little worse than expected, and it will not be possible to stick a traditional “motorist’s bag” to its surface with Velcro. The option of a rug with a pile covering will not be practical, since it is subject to the risk of contamination from spills of various liquids or dirt.

The rubber cover in the trunk can be easily placed on top of the standard one. If the niche for the spare wheel will be used for other luggage, then you should take into account the fact that one mat will rest against the niches on the sides of the trunk. If you place any object above the spare wheel niche, it will fall into its recess.

Methods for solving problems with door limit switches

We will look at a number of fairly simple ways to solve the problems described above, which every car owner can easily put into practice. Thus, if problems arise caused by the operation of limit switches in the winter months, you can resort to the following methods:

• Remove the anthers from the limit switches. Remember that these rubber caps serve a protective function, and therefore when removing them you will have to be very careful about cleanliness. It is recommended to remove the anthers only for a short time, in frosty weather outside.
• Replace the “original” caps with analogues. Anthers from other end caps, for example, Toprun, which are practically a copy of the original Granta caps, are suitable as analogues. However, these anthers are made from materials that do not lose their elasticity at sub-zero temperatures, which is their undoubted advantage. You do not need to change the end switches themselves, only the caps should be replaced.
• Install a spring under the switch boot. For this purpose, springs with a length of approximately 18-20 mm and a diameter of 12-13 mm with a wire thickness of 1 mm can be used. They need to be installed on the limit switch rod, directly under the anthers. A good spring will not allow the cap to be constantly in a compressed state and will not let you down even at a temperature of -40C.
• Lubricate all rubber surfaces with silicone, this will help in relatively mild frosts (about -10C or less).
• Treat the surface with a water-repellent liquid. This measure works in a fairly wide temperature range (up to -50C), but is purely temporary.

Lada Granta › Logbook › Adjusting the trunk opening force

Good day everyone. Can anyone tell me if on a Grant sedan it is possible to somehow regulate the force of the torsion bars of the trunk opening lid?

You don’t have to write advice like installing struts or springs. After looking at the mechanism, it seemed to me that without additional gadgets you can change the force, I just can’t figure out how.

According to the principle, there is the same mechanism as on the classics, maybe someone regulated it or there is a link to the material, otherwise I don’t come across something, but what I need is on the Internet

For clarification and in case I called something wrong, here is the mechanism for raising the trunk lid and theoretically it is adjustable. question - how?

How to open the trunk on a station wagon, sedan and convertible

Let's start with the simplest thing - these are station wagons. A station wagon is a car body that has a closed design. The luggage compartment in such a car has a common roof with the car interior. This suggests that you can get into the trunk of a car through the interior of the car. To do this, you need to remove the top shelf and the trunk will be within a meter of the driver’s hands.

If dismantling the rear parcel shelf is not provided for by the design of the car, then there are probably locks that hold the back of the rear seat. For example, on a VAZ 2121 Niva, you can unfasten special latches and the back of the rear seat will move forward. This way you can take the keys from the trunk without opening it.

This method becomes relevant for the latest model Niva, since the first SUVs of this series had a special button on the trunk lid designed to open the trunk without the participation of special levers in the cabin or the car key.

In the case of sedans, everything is much more complicated. This is especially true for older cars that do not have a special trunk release button. In the classic VAZ family of the fifth and seventh models, as well as the FIAT 124, opening the trunk is possible without using a key at all. The fact is that the lock of such covers is too simple and can be opened with a regular flat-head screwdriver. In this connection, it is recommended to replace the trunk lock with a more thoughtful one in the future. On other models, it is impossible to lock the trunk without a key.

A separate story is the Soviet car IZH 412 Moskvich. His trunk had neither a button nor a special lock. The trunk was locked using a special metal cable located outside under the trunk lid. To open the trunk, simply pull this cable to the right.

Despite the simplicity of the design, there were situations when this cable was bitten off when the trunk was closed incorrectly. In this case, access was lost not only to the trunk, but also to the car’s gas tank, which created additional difficulties when refueling the car. However, you can also open such a trunk. The whole process is complicated by the fact that between the seat and the trunk there are stiffening ribs that block access to the latter. To gain such access, you need to remove the fastenings of the rear shelf under the glass and remove it. Next, you need to reach with your hands the remains of the cable or locking mechanism and open the trunk manually from the inside.

Opening the trunk of a convertible is even more difficult. This is due to the fact that its trunk does not have any connection with the car’s interior and is made separately. To open it, you need to know the lock structure well enough. But in order not to spoil it, it is still recommended to call a specialist.

The trunk of modern cars can be opened without a key from inside the car using a special button for the electric trunk lock.

Preparatory stage

• impact screwdriver;
• cross bits;
• pliers;
• plastic clips in case of damage to the standard ones;

Procedure for independently replacing the driver's door lock on a Lada Granta Liftback

1. We install the car within the perimeter of the repair area and provide unobstructed access around the perimeter.
2. We take priority safety measures when carrying out work. We fix the rear row of wheels with wheel chocks and engage first gear to avoid arbitrary movement.
3. Open the driver's door, use an impact screwdriver to unscrew the two screws securing the shackle to the car body, and remove it from its seat. We install a new shackle with soundproofing material.
4. Let's start removing the constipation: unscrew the plastic float and remove the stem.
5. We unscrew the car door card, two screws, eight plastic clips around the perimeter.
6. We disconnect the block with wires from the double-glazed window control unit, speakers, and central locking.
7. From the outside, unscrew the three screws that secure the lock body to the door.
8. We remove the two rods, having first disconnected them with pliers.
9. We carry out preventive maintenance, clean the seat, remove old grease, and apply a thin layer of new one.
10. Let's start installing the new lock.
11. We assemble the structure in the reverse order, unless there are other breakdowns that require surgical intervention or elimination.

During the installation process, we pay attention to the integrity of the electrical wiring, insulating layer, terminals, and blocks with wires. If there are signs of wear, replace them with new ones.

Do not operate the machine with faulty electrical wiring.

Typical door lock malfunctions

• tightness of locking the door;
• increased noise when opening/closing;
• the central lock does not lock the door and does not respond to signals;
• unlocking is accompanied by a creaking, metallic grinding sound;
• While driving, the door vibrates, cracks are visible in the places of contact with the standard seal.

Common Causes of Premature Wear

• failure to comply with the deadlines for technical inspection, preventative maintenance, lubrication, and replacement of worn elements;
• third-party mechanical damage resulting in deformation of the door or lock;
• manufacturing defects at the factory;
• the lock has become loose due to loosening of the fastening;
• violation of the adjustment algorithm;
• human factor: systematically locking the door with force.

The defect is eliminated by replacing the constipation assembly.

Replacing the rear (passenger) door lock

The procedure for preventing locking of the front/rear passenger door is carried out by analogy. The design and method of fixation are typical.

Installing a trunk lock on Lada Granta Liftback

1. We place the car on a level platform and provide access to the trunk lid.
2. We take safety measures when carrying out work.
3. We unscrew two screws and remove part of the lower plastic trim of the trunk lid.
4. Unscrew the two screws securing the lock body to the trunk lid;
5. Using pliers, remove the rod from the button to the body.
6. We remove the constipation, carry out preventive maintenance, lubricate the threads and the rod end.
7. We install a new lock and assemble the structure in the reverse order.
8. We unscrew two screws, remove the standard shackle, install a new one with sound-insulating material.

Replacing the hood lock

1. Inside the car, under the dashboard, there is a hood release lever. We pull it towards ourselves.
2. Release the latch and lift the hood.
3. Using a TORX key set to “10”, unscrew the two screws holding the lock body to the body.
4. Using pliers, remove the cable eye from the seat.

Conclusion Limit switches on a car should always be in good working order. Provided proper maintenance and lubrication, the service life is at least two years. It is necessary to regularly analyze the condition of the limit switches in order to notice and prevent malfunctions in time. You should also adhere to the operating instructions.

Where is the trunk limit switch of the Lada Granta Liftback

The trunk lid activation sensor is located on the left side, closer to the lamp. However, it is installed only in the “Lux” configuration. Rubber plugs are inserted into “Standard” and “Norma”.

In order to prevent sudden activation of the central locking and door locking, owners optionally install sensors. Considering the simplicity of the procedure, you can do this either independently or by contacting a service station for help from specialists. After installing the trunk end switch into the seat, we lay and connect the electrical wiring. “Plus” is powered from the side lights of the lamp, “minus” can be from the body or on the block with wires. Black with a white stripe is “minus”, red is “plus”.

In the Luxury package, the sensor is built into the trunk lid lock by default. When the lid is closed, the sensor automatically turns off the power from the light.

General tips for installing alarms

• To supply power to the alarm unit, you should take energy only from the constant positive, which goes directly to the battery, bypassing fuse protection.
• It is best to attach the light indicator not to the dimensions (as recommended by the instructions), but to the turn signal network.
• If possible, the alarm antenna should be connected as close to metal parts as possible, as this will result in a better signal.
• After connecting all the elements, check and adjust the shock sensor to the optimal values.
