Car alarms today are installed on almost every car. In this case, during operation, for various reasons, it may be necessary to turn off the alarm. For example, disabling the alarm may be necessary if the driver leaves the car in a parking lot, closed garage or guarded parking lot for a long time.
Also, the alarm on a car often needs to be deactivated if there are malfunctions or malfunctions in its operation, repair work is being carried out, etc. One way or another, not all drivers know how to completely turn off the car alarm. Let's figure it out.
Causes of breakdowns
A car alarm may fail due to:
- Presence of radio interference. Such situations arise in large cities and megalopolises, where a large number of cars and other electronic devices accumulate. Intensely emitted radio waves can cancel out and interfere with each other. To solve the problem, you just need to come close to the car - and its sensor will recognize the signal from the “native” key fob.
- Damage to the control panel. If the key fob has been dropped, been hit hard, gotten wet, or its battery has simply run out, it may not work. To check the condition of the battery, just press the button and watch the indicator light glow.
- Car battery discharge. If the battery is dead, the electronics are left without power. Accordingly, the alarm system will not respond to commands from the control panel. You can open the car door with a key. But the alarm will go off. To avoid this, open the hood and remove the “-” terminal from the battery.
These and similar problems can be solved in various ways. At the same time, options are available with and without a key fob. Let's look at each effective method.
What causes problems with the signal system?
Incorrect operation of the security system can be associated with various problems. Most often, failures occur precisely because of poor-quality equipment. Extremely low or high air temperatures cause problems. Incorrect operation is also associated with malfunctions of the internal components of the device.
A problem may be indicated by overly sensitive operation or problems occurring when turning the equipment on or off. Motorists often encounter false alarms. All of these problems indicate that your vehicle's safety equipment is in urgent need of repair.
Problems with a faulty key fob can be caused by the following reasons:
- Too much radio interference that interferes with the normal operation of the alarm panel;
- Problems with the car battery;
- Low battery.
If the breakdown is due to a dead battery in the key fob, try taking it out, shaking it slightly and putting it back in place. Manipulations of this kind will help to revive the device for a few minutes. Don't forget to replace the dead battery.
Very often, problems with the signaling arise due to a dead battery in the key fob.
Turn off the alarm when there is no key fob
If the “signaling” control panel turns out to be inoperative or useless, to “bypass” it you need to know the location of the Valet button. It switches the alarm to service mode. If the “alarm” is not calmed down, then reliable protection of the machine is maintained.
Where is the Valet button located? It is impossible to answer this question unequivocally. Car manufacturers and technicians specifically install it so that an unknowing user cannot quickly turn off the alarm. This increases the safety of operating the car, because possible theft becomes more difficult. TOP Valet button locations:
- Fuse box.
- Bottom of the dashboard.
- Pedal area.
- Glove compartment area.
- Steering column area, etc.
The guideline when searching for the treasured button is the location of the LED indicator - they are located not far from each other. The location of Valet is indicated in the car’s user manual, in the “signaling” manual. And if you are buying a used car, then check this point with its owner to avoid a grueling search.

Switching the system to Valet mode
In a situation where the “signaling” cannot be turned off from the key fob, one of the easiest options to turn it off is to switch to Valet mode. We recommend that you find out how this is done in the technical manual for the alarm, which is included in the package.
You need to start by looking for an emergency button installation. If the “alarm” was installed independently, the car owner must know where it is installed. Installers usually place it under the control panel or near the safety component block.
When you find the car alarm service key, follow one of the following algorithms:
- Place the key in the ignition, turn it to the ACC position, then click the emergency button four times. After this, return the key to its original position.
- Insert the key into the lock and turn it to the ignition position, click the emergency function button once. The ignition will be deactivated.
- After performing the above steps, start the engine and reconnect the siren contact.
The procedure for entering Valet emergency mode may vary.
User Kolya Kolya talked about how to turn off the emergency Valet function.
Disabling the car alarm
Not entirely loyal, but effective, is to cut the cable directed to the external speaker. True, modern protection systems are multi-stage. And this method does not always help. But you can try it. An alternative solution is to find a fuse relay for power supply and control of the “signal”. It can be neutralized with wire cutters or simply pulled out by hand. But relays and fuses are often wireless and “hidden” in the most unexpected places. Therefore, their search may take a couple of hours.
Let's sum it up
To turn off the alarm when the key fob breaks, you don’t have to perform complicated steps. It is enough to know where the speaker is and simply turn it off until the circumstances of the breakdown are clarified. Remember that the alarm system works without a speaker, so fix the problem as quickly as possible, otherwise your car’s battery will soon become unusable.
You should not drive a car for a long time if it has problems with the alarm system. This is unsafe and inconvenient, so it is better to solve this problem at a professional service station. Have any of our readers ever had to turn off the alarm on a car without a key fob?
How to disable Alligator
Another popular auto protection system is “ALLIGATOR D-810”. It can be disabled as follows:
- Enable function No. 9 (see the manual).
- Open the car interior with the key.
- Turn on the ignition.
- Press the Valet button.
- Turn off the ignition.
After performing these actions, the “signaling” will be neutralized, but will not be transferred to service mode. Therefore, it is necessary to deactivate it in accordance with the manual before closing and locking all doors.
Dismantling Guide
It is necessary to remove the old alarm from the car when installing a new one. Removing the main car alarm unit may be necessary when updating the software or updating its settings so that it meets the security requirements of modern security systems. Sometimes it is necessary to dismantle parts of the anti-theft system for repair and replacement (video author - SpetsAvtoSystems).
Modern security systems reliably protect cars from theft and entry; they have an increased degree of protection against code reading and interception.
You can install a new one instead of the old one, and the installation can be performed on a car of any brand. But before installing a new security system, you need to remove the old one. If you are changing the alarm system, then find a diagram for the old alarm system and connect the new one to the same places, this will make your work much easier.
Tools and materials
It is difficult to dismantle the alarm system, since its elements are hidden as far as possible so that they are invisible. Many owners do not know where the car alarm is installed, so it is better to entrust the dismantling to specialists.
If you decide to dismantle the anti-theft system yourself, you will need a small set of tools:
- screwdriver;
- multimeter;
- side cutters;
- insulating tape.
In addition to tools, dismantling work will require patience.
Disabling the alarm without a key fob
Stages
Dismantling the anti-theft system consists of the following steps:
- First of all, you should turn off the power to the car by removing the negative terminal from the car battery.
- First you need to find the LED on the dashboard. A wire goes from it to the control unit. It is necessary to disconnect the connector with wires.
- Now you can disconnect the standard wiring from the electrical power system, and you also need to remove the immobilizer.
- The electrical circuit of the anti-theft system is connected to turn signals, side lights, hood, trunk, door switches, and engine blocking. When removing each element, it must be correctly disconnected from the car alarm.
- Next, you need to remove the shock and internal volume sensors, which are usually located under the handbrake lever.
- You should be very careful when disconnecting the contacts on the motor. Modern security alarms are equipped with locking mechanisms for the starter, fuel pump and ignition system.
- After disconnecting the contacts, you need to find and dismantle the Valet service button, as well as the siren, which is located in the engine compartment. After removing the fasteners, you need to remove the wiring coming from the interior.
- Now you can try to start the engine. If the alarm was correctly removed, the engine will start without problems.
Dismantling an old car alarm
If the anti-theft system is dismantled on your own, then if dismantling is incorrect, the following consequences are possible:
- the integrity of the electrical wiring is compromised;
- malfunctions of electrical equipment;
- the decorative trim of the interior is damaged;
- engine starting is blocked for no reason;
- the removed element is damaged and can be reused;
- damage, the elimination of which can be costly.
How to disable Leopard
The most common versions of auto protection are “LEOPARD LS 90/10 EC” and “LEOPARD LR435”. The algorithms for disabling them are similar to Sherkhan. It is also possible to use a personal code. In this case, you should perform a number of actions:
- Open the car with the key.
- Sit in it.
- Turn on the ignition.
- Press Valet as many times as indicated by the first digit of the code.
- Turn off the ignition.
- Turn on the ignition.
- Press Valet as many times as indicated by the second digit of the code, etc.
What causes a car security system to break down?
Any system that includes individual elements is subject to wear and tear during operation. Anti-theft systems are by no means exceptions. Emergency situations often arise that make the car owner seriously nervous.
Within the framework of the problem presented, it would be quite appropriate to make a small digression. You need to understand that the uninterrupted operation of a car’s protective systems depends on a number of factors. At the forefront is comprehensive systematic maintenance and care of the elements of this device.
How to disable FALCON TIS-010
To transfer the immobilizer to service mode, you will need a PIN. Algorithm of actions:
- Opening the door with a key.
- Turn on the ignition.
- Pressing Valet three times within 3 seconds from the moment the indicator starts flashing.
After performing these actions, the light turns on for 5 seconds and then blinks slowly. Now you need to count the number of flashes. When it matches the first digit of the PIN, press Valet. Then counts the number of flashes for the second and subsequent code numbers.
Expert answer
Immobilizers APS-6, as well as APS-6.1 (Grant) do not turn off after activation. You can set an individual code to use later. First you set the code, then use it if you lose the key tag. There are no other options.
There is no secret sequence for disabling APS-6 (6.1). And if the code has not been set, then if the tags are damaged, starting the engine will not be possible.
First we set the code
- The ignition is turned on and off with the “red” (learning) key. The lamp flashes;
- Within 6 seconds (the new option is 2 seconds), the “black key” is installed and the ignition is turned on. 3 beeps sound;
- Two more signals sound, within 6 or 2 seconds the ignition is turned off, and the key is replaced with a training key. Turn on the ignition;
- Three signals will follow, then two more;
- Turn off the ignition and wait for a single signal. The flash frequency of the lamp will double;
- Turn on the ignition. The Check indicator should be on;
- When the indicator goes off, go to step 8;
- Entering a number: first, short presses on the gas, then one long press. In total, you need to specify six digits (from 1 to 9);
- In the last step, when pressed for a long time, the Check indicator does not go off. Turn off the ignition - the entry is complete.
If in step 8 you immediately press the pedal for a long time (more than 5 seconds), the “old code” is erased and is no longer used. Be aware of this.
Training key - on the right
Engine starting
- Turn on the ignition without using the tag;
- Wait for the Check indicator to go out;
- Enter the code as discussed above (step 8).
Explanations: short press – no more than 3 seconds. And a long one - until the indicator goes out, although when you enter the 6th digit it does not go out. And if this is so, then everything was done correctly.
How to disable KGB
Algorithm of actions:
- Opening the door with a key.
- Turn on the ignition.
- Press Valet once in the first 10 seconds.
After this, the KGB VS-100 auto-protection will be disabled and the engine can be started. And in the KGB VS-4000 version, there will be an additional pair of sound signals in the car, and four in the key fob.
Available emergency deactivation functions
How to disable the immobilizer on a VAZ-2114 with your own hands
For each developed Starline b9 car alarm system, an individual code is provided, the introduction of which is necessary for emergency shutdown, and it is also possible to deactivate special sensors when the security mode is turned on. It is also possible not to deactivate the sensors, but only to disable the warning area in which these sensors operate. Some people find it interesting to be able to open each door individually using such a car alarm. In addition, there is an active Anti-Hi-Jack function. The car can be set to alarm even when the engine is running and there is no key in the ignition.
In this case, you cannot ignore the standard function of automatic activation of the security mode. Naturally, a necessary option that allows you to bypass the faulty zone, as well as taking into account the delay of lighting in the cabin, which slowly fades from time to time. In addition, the list of capabilities of such a car alarm system includes the function of controlling interior lighting. The case itself even has an additional output for a special custom sensor. Naturally, this car alarm system provides outputs for the hood and trunk lid limit switches.
Activation of the standard immobilizer in Lada Granta
The need to activate the Lada Granta immobilizer may arise completely unexpectedly when an attempt to start an unauthorized car engine is detected. But there may be a reasonable solution when the owner of a Lada Granta car changes or the working keys are lost. In any case, knowledge of the procedure for activating the immobilizer will not be superfluous
Important: if you need to train another working key, you should repeat episodes No. 3 – 5 with it. If this is not required, then activation of the Lada Grant immobilizer can be continued from episode No. 6.
Immobilizer operation diagram on video
This is the most primitive way to disable the immobilizer. To be precise, this is not a shutdown, this is its “destruction.”
Recently installed the A93 2CAN-LIN + GPS-GSM system.
The purchase and installation was carried out at the only branded installation center in Volgograd.
* when arming, the interior light does not turn off.
At the moment, installers shrug their shoulders and say “this is AvtoVAZ.”
But as far as I know, “it is AvtoVAZ” that has certified Starline and sells it in branded showrooms in branded packaging. Those. this argument is not very convincing.
An immobilizer is an electronic anti-theft system that blocks part of the vehicle control modules when intruders enter the car. Such protection is a mandatory attribute of most modern middle and upper class cars. Despite belonging to the economy class, the Lada Granta immobilizer is also included in the standard factory equipment.
