The variety of cars on the roads of our country can capture everyone’s imagination. However, among our car enthusiasts there are those who would never trade their beloved “nine” for anything. Indeed, the VAZ-2109 rightfully deserves to bear the title of cult, because many of us gained experience behind its wheel. However, we should not forget that at first universal love was very difficult for the car. Not least because of trivial problems with the trunk and hood locks. What can we say, many VAZ-2109 owners still repair these car parts, sparing neither effort nor time.
Hood lock VAZ 2109
There was a need to open the hood of the Nine, I pulled the handle from the passenger compartment and felt that something was wrong. Usually you pull the handle and hear a click, but now there was no click and the handle was difficult to pull. I leave the cabin, go to the hood and open it. I see a hood cable with a broken spring. Everything is clear, the hood lock spring has broken. It's very easy to change it. We buy a new spring.

First, we take out the old broken spring.

Then we insert a new one and first of all we put it on the cable as shown in the figure. Now you need to insert the second end of the spring into the locking hole.
The hood won't close
Okay, everything turned out quick and easy. I close the hood, but it doesn't latch. It is necessary to adjust the protrusion of the spring with a screwdriver and lubricate the contact point with machine oil - in order to pull the handle out of the hood with less effort.

After this, you need to develop a hood lock - open and close it several times. Now the hood latch has been adjusted and designed to keep the hood securely closed when the car is moving. The hood of the car is equipped with a special latch that will prevent the hood from opening if the hood latch opens while driving.
Hood safety latch
If this safety latch did not exist, then when the hood latch spontaneously opened with a gust, the hood would open while driving.
Installation of sports locks
Sports hood locks can be installed instead of standard parts or as additional insurance. It is recommended not to abandon the original locking mechanism; this is an additional guarantee that the hood will not be opened by intruders; the latches on VAZ cars are quite strong and can withstand significant mechanical forces if they are opened.
Preparing for installation
Before installing the sports lock, it is necessary to accurately measure the places where the rods are attached on the bar.
- Holes are drilled in the frame above the headlights and rods are installed.
- the tops of the rods are smeared with grease, and the hood lid is covered so that fingerprints remain on the lid.
- On the hood, on the printed marks from the rods, the necessary holes should be drilled.
Hood drilling steps:
- The hood cover is drilled from the inside out.
- Take the smallest drill and drill a hole on a solid wheel.
- The hole is expanded with a large drill.
- Checking holes for additional boring.
- The hole should be 1-2 mm away from the rod.
The preparatory procedure before installing the sports lock is completed.
Lock installation
Installing the lock also requires using a drill to secure it to the hood. Stages of work:
- For example, the protective coating is removed from the plate on the hood lock of a VAZ 2106, the plate is applied to the hood and the four mounting holes for the plate are measured.
- Use a thin drill to drill the cover for the screws.
- The plate is screwed on with self-tapping screws.
- The rods are tightened to the optimal position.
- Studs are inserted into the holes of the rods.
- Installation of safety cables.
- Installation completed.
Of course, repairing and adjusting the lock is not a complicated procedure that you can easily do yourself. A well-reinforced hood means driver safety on the road; it’s hard to imagine what the consequences of a hood suddenly opening on the highway could be.

Replacing the hood lock on a VAZ-2109 - we solve the problem ourselves
The variety of cars on the roads of our country can capture everyone’s imagination. However, among our car enthusiasts there are those who would never trade their beloved “nine” for anything. Indeed, the VAZ-2109 rightfully deserves to bear the title of cult, because many of us gained experience behind its wheel. However, we should not forget that at first universal love was very difficult for the car. Not least because of trivial problems with the trunk and hood locks. What can we say, many VAZ-2109 owners still repair these car parts, sparing neither effort nor time.
General advantages and problems
Before considering the implementation of solutions among hood locks, it is worth saying a few general words regarding all hood locks at once.
Hood latches are important and necessary. Along with the alarm. While the siren locked under the hood is screaming, the attacker cannot feel confident. Hood locks are loved and popular also because they contain some uniqueness, a trick or something. Their importance is not obvious enough to an uninitiated person “on the spot,” but after the essence is explained, the customer feels like a real “cunning person.”
There is, however, a whole range of problems that, to one degree or another, apply to all hood locks, and are clearly not in their favor.
Replacing the hood lock on a VAZ 2108, VAZ 2109, VAZ 21099
Welcome! Before we start replacing the hood latch, let's take a look: What is included in the so-called hood latch? Firstly, the castle includes:
• Two hood release handles. (One handle is installed in the cabin, and the other is located in the engine compartment)
• The lock also includes the lock drive cable itself, as well as the hood latch and safety hook. Read below for all the instructions for replacing lock components.
Note! When replacing the hood lock, you will need a screwdriver, as well as wrenches and thin pliers!
Summary:
When do you need to change the hood latch components? • For example, the handles used to open the hood of a car must be replaced if they break or are otherwise deformed, making it difficult or even impossible to open the hood of the car.
• The lock drive cable must be replaced if it is broken or deformed, due to which it will also be impossible to open the hood of the car.
• The hood latch and the lock spring need to be changed if they are also deformed, because as a rule, if they are heavily worn or distorted, the hood of the car can spontaneously open while driving.
Causes
Initially, you need to ensure the integrity of the lock itself and its elements; if something is broken, you will have to replace it. Let's look at the main causes of breakdowns that you can actually fix yourself. The hood may begin to close poorly due to the displacement of the position of the lid or its latch. This can be corrected by simple adjustment, having with you a 13 mm wrench and a screwdriver. You just need to move it in the desired vertical or horizontal direction.
- If you have to make significant efforts to close the hood, but you still manage to slam it, this does not mean that the problem is solved. This fact only means that the height adjustment of the latch is broken, the play is noticeable, and the hood will bounce and rattle while driving. The solution to this is to loosen the lock nut of the latch with the same key, while holding it with a screwdriver so that it does not turn with the fastener.
- There are cases when the latch has moved horizontally, then when closing the hood you will feel a hard blow, and opening it is problematic. It is necessary to adjust as follows: loosen the lock nut and move the latch to the desired location. Before tightening the nut, you should check that the hood closes easily and tightly. If you did not achieve the desired result, then you should repeat the steps.
- Sometimes the hood needs to be adjusted in relation to the latch and fenders. This happens if the lock does not lock and the lid does not fit into the space allotted to it. In this case, it is necessary to open the cover and loosen the mounting bolts. Smoothly lower the lid without clicking the lock, and set equal gaps along the edges by simply pulling the hood in the desired direction. You can use identical pegs and insert them between the hood and fenders to achieve the ideal. When the gaps are set, lift the hood and tighten the mounting bolts.
Next, let's look at the reasons that are more difficult to eliminate:
- fatigue of the metal from which the spring is made. It is inserted into the “TV” and weakens over time, which is why it does not work properly. You should pull it - if the resistance is weak, it means it is faulty. The solution to this is a simple replacement of the spring;
- support tins are another possible reason that the hood on the VAZ-2115 does not open. They sometimes break or become loose. In this case, you can close the hood. It is necessary for one person to pull the handle that opens it, and the second to slam the hood. The fact is that the entrance to the lock guide should not be closed by the spring, while being to the side and covering only a third. If this is not the case, then the support washer will bend, it will be necessary to straighten it and place another one. This defect can be corrected by shortening the cable going to the lock.
The last reason is best left to a mechanic to avoid damaging the cable. It should be noted that these are almost all the reasons why the hood of the VAZ-2115 does not close, and ways to solve this problem. If you cannot determine what the problem is on your own, it is best to contact a mechanic. We hope that your car's hood will both close and open without any repairs.
How to replace the hood lock elements on a VAZ 2108-VAZ 21099?
Replacing the lock spring:
1) To remove the lock spring, first disconnect the drive cable from it.
2) Then use a screwdriver to pry it up and remove it from the car body.
Note! To install a new spring in place of the old one, do the entire operation in reverse order!
Replacing the lock drive cable:
The lock drive cable can be removed without removing the spring, to do this:
1) First, remove the drive cable from the fastening lock.
2) Then move into the car interior, and then unscrew the bolt that secures the hood release handle.
3) Next, remove the lock handle and, using pliers, straighten the end of the cable.
4) After straightening the end of the cable, slide the metal sleeve up.
Note! When the bushing is moved, remove the cable loop from the lock handle!
A few more common installation-related features
The effectiveness of the hood lock sometimes greatly depends on the professionalism and conscientiousness of the installer (you can depend on working conditions and much more, but it seems to me that everyone understands what we’re talking about). This is a general rule for all universal designs; nothing can be done about it.
For mechanical models it is desirable:
Ensure the secrecy of the installation of the larva. The point is not even to hide the larva itself, but to prevent the attacker from getting to the armor and getting the cable.
Hood lock failed
There are different types of malfunctions in cars. Some we notice right away. For example, if the engine stalls, the starter stops turning, the power windows or central locks don’t work, fuses blow out, or a light bulb doesn’t light up—we take immediate action. But we simply do not notice many malfunctions that arise gradually. The repair of the hood lock can be attributed to just such a case.
The hood lock is one of the first places on the list of “gradual” breakdowns. In rare cases, it breaks suddenly (it worked perfectly and suddenly...). The deterioration of its work manifests itself, so to speak, step by step. Well, he slammed the hood again, slammed it again with more force. It finally closed, well, okay... Yes, the hood closed, but was it secure? Won't this little thing cause trouble for the careless car owner? As you know, in most cases, danger creeps up from the side from which it is not expected.
Classification
Let us recall that among the variety of transmission locks, a certain trend has already emerged that generalizes the development from the past to the future. For example, among the Bear-Lock lock models, the ratio of individual pin locks to pinless locks is approximately 900:150, while Defend-Lock is focused only on pinless locks. It is obvious that the founders of the industry - universal arc locks - have practically left this world, and their successors - universal pin locks - are also gradually dying out.
Nothing like this is happening yet among the additional hood locks. All the solutions that were created in this direction are still “more alive than all living things.” And individualization, adaptation to the car model, for hood locks is manifested mainly in the provision of specific additional brackets to facilitate installation and protective elements against opening.
Problems with the hood latch
What functions does the hood lock perform?
The main purpose of the hood lock is to keep the car's hood closed in any conditions (whether the car is parked or rushing along the highway at a decent speed).
Yes, most designs are not satisfactory, but they (over time) do not provide adequate safety. The main thing is to catch the moment when such “nonsense” as the hood lock should be replaced or repaired.
What he shouldn't do
You are just starting to have problems with your car's hood lock if:
- To close the lock, you have to slam the hood several times, each time applying more and more force.
- The hood rattles and “bounces” on potholes
- It became problematic to open the hood, the handle in the cabin does not respond well.
If you are familiar with these inconveniences, then it’s time to think about adjusting, replacing or repairing your car’s hood latch.
Timely diagnostics and repair of vehicle components will save you from problems and unnecessary costs of time and money.
Replacement, repair or adjustment?
To begin with, let’s define the problem that has arisen and the scale of the upcoming work.
- If the lock jams occasionally, and the hood rattles noticeably when the engine is running, then a simple adjustment will help.
- If there is constant jamming and futile attempts at adjustment, the locking mechanism or cable drive requires repair or partial replacement
- In case of very serious damage (warped, crumbled, etc.), only a complete replacement will help.
Using a superficial inspection method, you can determine whether a given device requires replacement or can be repaired. Let’s say that after an examination we determine that “the patient is more likely to be alive than dead,” and he can still be resuscitated.
What are sports locks?
What are their functions?
Many people who saw strange, symmetrically located devices on the hood of a car for the first time had a similar thought: “What can people come up with to stand out from the crowd!”
Yes, these accessories really give the car a new, sporty, aggressive look. That's all? Is it worth it to poke holes in the hood for the sake of a dubious change in appearance? In fact, sports hood locks, in addition to decorative functions, perform another important role.
Driving safety
It is not uncommon for a car to open its hood while driving. And this happens not only with “old” vehicles. It’s good if everything gets done by replacing the hood, windshield, straightening the roof, followed by paint work. All this costs a lot of money and, most importantly, nerves. How to insure yourself against similar and more serious troubles?
Additional hood locks of this type are designed precisely to prevent such situations. These were developed for racing cars, and now no sports car will be allowed to participate in a rally without them. An open hood, and even on a race track... This is where they got their name, and are now known as “sporty”.
Hood lock repair
There are about as many modifications to hood latches as there are car models. If you have problems with its operation, first of all you should understand the design features of this mechanism.
Hood lock device
On almost all cars they are mechanical, and consist of similar main parts. Let's take a closer look at this device using the example of the VAZ-2109, since the hood of this car has a bad habit of opening while driving.
- Latch pin
- Bottom cup
- Safety hook
- Lock washer
- Hook spring
- Hook axis
- Upper cup
- Latch spring
- Rod shell bushing
- Handle axis
- Lever
- Rod seal
- Sheath thrust
- Rod holders
- Lock spring.
There are a lot of details, but the principle of operation is clear. When closing the hood, the pin enters the hole in the frame and is secured by the lock spring. By pulling the rod handle, we release the pin. A gap forms between the hood cover and the car frame. The hood is held only by a safety hook, by pressing which we open the lid completely. Difficult? Yes, it’s much easier, I pulled the “string” and the door opened!
Let's start repairing the castle. All we need from tools are several keys (at “13” and “19”), a flat-head screwdriver and pliers (preferably thin ones). This can be found in any car or garage.
Replacing the lock spring
As we can see, practically the only element of the locking mechanism on the frame is the metal lock spring. It turns out that she is the main culprit for the spontaneous opening of the hood!
Metal, as you know, “gets tired” over time. Timely replacement of the spring can save the car owner from a lot of trouble.
So, let's change the spring!
First of all, disconnect the drive rod from the spring.
Using a screwdriver we release...
And remove the spring.
Three movements and you're done! Installing a new spring occurs, as you may have guessed, in the same way, only in reverse order.
We've sorted that out, let's move on. Have you ever encountered such a situation? When you pull the handle in the cabin, you can clearly hear the click of the hood lock. You get out of the car, but the lid does not open, there is not even a gap where you can insert your fingers. Here you can’t do without an assistant; one pulls the handle, the other tries to lift the hood lid. If adjusting the latch position does not help, the spring is again to blame (responsible for the “bouncing” of the lid). Only this time it is already on the latch pin.
1 Troubleshooting the trunk lock of the “nine”
It just so happens that low-quality locks accompany almost all representatives of the VAZ model range. At the same time, a clear pattern emerges: the newer the Lada model, the easier it is to replace the lock in its trunk and hood. Thus, installing locks on a Lada Grant does not require any special skills and takes a maximum of 20 minutes of time. The same cannot be said about the work of replacing locks in the trunk and hood of a VAZ-2109. “Nine” blockers are more complex designs, which is why you will have to tinker with them a little.
But, as they say, let's start in order. The first thing that VAZ-2109 owners should know about is the constant need to adjust the trunk lock latch. There are many cases where the owner took the car to a car repair shop with an urgent need to replace the lid lock. Then it turned out that the lock was working, just its lock had moved a little. Therefore, in order not to repeat the fate of those poor fellows, we will study the algorithm for self-adjusting the latch.
Repairing the trunk lock of a “nine” involves removing the trim. To do this, use a screwdriver to pry up the 10 fastening pins and remove them. We remove the casing and start working with the blocker. First, using a socket wrench or wrench, unscrew the 2 nuts securing the lock on the trunk lid. This must be done extremely carefully, since immediately behind the fasteners there are 2 “negative” terminals. We also disconnect them, after which we pull the lock out of the hole in the trunk lid.
Next we work directly with the fixative. To dismantle it, remove 2 mounting bolts. After this, we determine the optimal position of the part and screw the clamp into place. If the problem lies not in the latch, but in the lock itself, then we continue to work further.
Remove the adjusting washers and pull out the entire lock. Next, we install a new blocker. To do this, we place it in place of the broken part and tighten the fastening nuts. We assemble all other parts in reverse order. At the final stage of replacing the lock, we fasten the trunk lid trim.

Before we start replacing the hood lock , let's see: what is included in the so-called hood lock? Firstly, the castle includes:
Two hood release handles. (One handle is installed in the passenger compartment and the other in the engine compartment)
The lock drive cable itself, as well as the hood clamp and safety hook, also belong to the lock. For complete replacement of lock parts, read below.
When replacing the hood latch, a screwdriver, wrenches and thin pliers will come in handy!
When do I need to replace the hood latch components?
For example, the handles that open the hood of a car must be replaced if they break or are otherwise deformed, which may make it difficult or impossible to open the hood of the car.
In case of breakage or deformation, the drive cable must be replaced, which makes it impossible to open the car hood.
The hood holder and retaining spring must be replaced if they are also deformed, as is usually the case with severe wear or distortion, the car hood may open spontaneously while driving.

2) Then unscrew the latch using a screwdriver and then remove it.
To replace the latch, perform the entire operation in reverse order!
Hood modernization and maintenance
In order to make the hood operation even more convenient, you can install a gas stop on it, which ensures almost automatic opening.
For this you will need:
- 2 stops;
- keys for 13;
- drill;
- drill 8 mm;
- bitumen.
The installation is performed like this:
Open the hood and put it on the stop. Drill 4 mounting holes, measuring 530 mm on each side of the hood (the distance between the holes themselves will be 310 mm)
In this case, two holes should be drilled in the body and two in the hood itself (it is important not to overdo it and not drill through it). Carefully coat the holes with bitumen to prevent corrosion. Place the gas stop in place and secure it with bolts. Install the second gas stop in the same way. As you can see, this operation is also quite simple and will not cause any particular difficulties
At the same time, such tuning can be very convenient - the hood, equipped with gas stops, will open on its own after a slight push with your hand, and when closing it will lower smoothly

VAZ 2114 hood with gas stop
Finishing the conversation about adjusting and replacing the hood, we should say a few words about caring for it.
The first thing worth noting is the need to periodically inspect the condition of the hood. So, if opening/closing becomes difficult, rattling or extraneous sounds appear, you should immediately check the fastening of the hood of the VAZ 2114 and, if necessary, fix it. If this does not help, then you need to perform vertical and horizontal adjustments, as discussed above.
The second thing you should always pay attention to is pitting corrosion. Even the smallest pockets of it should be removed - this will help avoid complete rusting and destruction of the hood in the future.
Small spots of rust should be cleaned to bare steel, then the cleaned area should be coated with a phosphating solution, primed and painted with automotive enamel.
Hood lock functions
The purpose of any locking mechanism, be it the hood lock of a VAZ 2109 or a BMW, is to tightly hold the engine compartment lid, preventing street dirt and water from entering the engine compartment. The engine compartment is provided with optimal ventilation, but air penetration should not occur through the cover.
The “disease” of 90% of VAZ cars is that six months after use, the hood lock begins to deteriorate: the cylinder wears out, the springs lose their rigidity, the cable (traction mechanism) frays, and cracks can form on it. Therefore, the lock should be adjusted twice a year, replacing, if necessary, faulty parts. Otherwise, a sudden opening of the hood on the highway is guaranteed.
Hood lock device
The entire VAZ line has a mechanical lock device, with similar main parts. VAZ 2114, 2115 have additional plastic protection installed under the bumper. This is important to remember when the cover jams after the cable breaks. Otherwise, the locking mechanism has the following parts. Using the example of the hood lock of the VAZ 2110.
- latch pin;
- springs - lock latches, hook;
- lock-nut;
- lock washer;
- hook - hook axis, handle;
- cups - upper, lower;
- traction mechanism - holders, bushing, seal, shell;
- lever.
The lock on the entire line of Zhiguli cars works extremely simply: by slamming the hood, the pin falls into a standard hole on the frame and is held in place by a spring. By pressing the traction handle in the passenger compartment, the latch is released, opening a small gap. By pressing the safety hook handle, the lid opens completely.
Mul-T-Lock Hood-Lock, Sentry HL Navigator, Dragon, etc.
In this case, only the general design is the same for all names - a mechanical blocker of a standard cable, operating on the “in reverse” principle (the author does not have accurate information whether under all the names listed above there are blockers operating on the “in the break” principle, they are common not so much).
Mechanics without any electricity. High security lock cylinders with complex double pins. Complete versatility - sheaths and cables of the required size are cut by the installer. However, the manufacturer of Dragon hood locks supplies individual brackets for fastening the cylinder and protective elements for the cable, which differ by car brand. Thus, the process of individualization begins its march among hood locks.
Implementations of this type of blockers from different manufacturers vary:
- material of the larva and its body;
- cable armoring device (including materials);
- materials of the case and mechanism elements;
- burglary protection elements;
- Sentry HL Navigator locks are equipped with shear bolts for fastening the cylinder body, and Dragon locks are equipped with shear fasteners, which, in addition to the bolts, include a protective hardened plate.
