How to turn off the alarm on a VAZ 2115 injector

The device of the standard immobilizer APS-4

First, let's figure out what this immobilizer model is and what functions it does. This kind of device is designed to prevent your car’s engine from starting in cases where access to it is recognized by the system as unauthorized, in other words, in the event of a possible theft.

This can lead to a complete replacement of control and monitoring units in the event of defects. When the ignition is turned off, the immobilizer is activated automatically (the buzzer will emit a small sound signal, and the indicator will go into flashing mode every 2.5 seconds), switching to the theft protection mode.

Factory method of disabling the alarm

Disabling the alarm using the factory method comes down to the fact that you need to use a combination of simultaneous pressing of the “Valet” button and any pedal (or pair of pedals) preset in the service center. This extremely important information is always clearly stated in the instructions included with the car or alarm (so it is important to pay attention to this when purchasing one or the other).

If, for some unknown reason, there is no such booklet, then the only way out is to try all the combinations, using all the pedals in turn, and then three possible pairs of them. The most common combination is to simultaneously press the service button and the clutch pedal.

Tip: to put the car into service mode, you need to hold the button and pedals for about 10 seconds - that’s how long it takes for the car’s electronics to recognize the command.

If after this time the car alarm emits several short trills at a certain frequency, and the side lights come on and go out in a synchronized manner, this means that the shutdown was successful. In this case, the light-emitting diode installed in the car should go out.

If, after the alarm was turned off, you needed to start the car a second time (for example, if it stalled), then you will not need to repeat the procedure described: the alarm program will notify you that the electronics are still in service mode with two or three short periodic beeps. sound signals.

Advice: after installing the alarm on your car, it is recommended to try turning it off and on yourself several times, bringing the actions to automaticity. In the future, this will help avoid panic in emergency situations.

Possible performance problems

With this simple method you can turn off virtually any alarm system.

How to disable (unlock) the alarm on your car if, for example, your batteries are dead...

At first, there were often cases of manufacturing defects when the system simply stopped working for no apparent reason. You also need to carefully monitor the maintenance of your battery in working condition (especially in case of long periods of downtime in the cold season) - a complete discharge of the battery is guaranteed to force you to seek help from the nearest workshop, followed by replacement of the electronic control unit of the anti-theft system, which will result in unnecessary additional expenses.

Coded alarm deactivation

The coded method of disabling the alarm involves pressing the service button a certain number of times (this number is called the “pin code”). The sequence of actions is as follows:

1. The car ignition is turned on.
2. The service button is pressed the number of times corresponding to the first digit of the PIN code (for example, if the PIN code is 25, then the button should be pressed twice).
3. The ignition is turned on again.
4. The service button is pressed the number of times corresponding to the second digit of the PIN code (in the above case – 5).

Obviously, this disabling method is more individual than the one described earlier, since the PIN code can be set manually. So, the maximum value for it is 9999.

Using a coded method to disable the alarm, cars are often stolen by criminals, since in most cases the PIN code set at the factory is a relatively small value. That is why it is advisable to set a complex parameter for the PIN code, containing a random set of numbers (which has nothing to do with any dates, etc.).

It has been repeatedly said above that the process of removing a car from a particular company’s alarm system is strictly individual, and there is no universal method suitable for each system. Therefore, it makes sense to separately analyze the alarm systems of certain models.

For Starline A1, A2, A4, A8, A9 models, the shutdown algorithm is as follows:

• The car is opened with a key;
• The ignition turns on.

Over the next 20 seconds, you must have time to press the service button 3 times (4 times for A8 and A9). After the system counts down the specified time from the moment the engine starts, it will emit a corresponding sound signal. Then the car can be turned off and started an unlimited number of times.

In exactly the same way, the alarm system of Tomahawk and Pantera alarm systems is turned off. Pantera models differ in that before pressing the button the car must be started twice (after the first start it must be turned off).

The Starline A6 model is different in that it uses a pin code as a shutdown tool, so in 20 seconds you need to press the button not three times, but a strictly defined number of times. The process of removing a car from this type of alarm system is described above.

Alligator alarms differ favorably from others in that entering an incorrect PIN code three times automatically blocks all car systems for a certain time (usually half an hour), which thus additionally protects the car from theft by intruders, eliminating the possibility of selection. The principle of disabling the security system does not have any distinctive features, but the time for pressing the button is limited to 10 seconds.

A very unique method of switching the alarm system to the off state is offered by the company Scher-Khan, the essence of which is the need to move the car’s ignition key to the “On” position from “Lock” in a limited time. Thus, the Magicar 6 model is one of the safest, since to disable it you need to:

1. After opening the car with the key, move the key three times in 4 seconds from the locked position to “On”. Then the car must be turned off.
2. The ignition is turned on again, and the number of key position changes is the first digit of the specified PIN code. The car turns off again.
3. The described operation should be repeated until all the numbers have been entered into the system in this way. The sound signal will then turn off and the side lights will flash twice.

In the case of the Scher-Khan Magicar 6A alarm, you must also wait for permission to enter the next digit. If the key does not turn after starting the engine, you should wait a little.

Thus, complete deactivation of the entire security alarm system can be carried out without a control panel. To do this, you need to remember either the combination of simultaneously depressed pedals and the service button, or a PIN code, which is recommended to be set manually. If the key fob does not work, the main thing is not to panic, but to calmly get into the car and confidently carry out the procedure for disabling the system.

Methods for disabling the VAZ-2115 immobilizer

If you don’t have the skills to reprogram a security system, but don’t want to make charitable investments in favor of car services, that’s okay. The solution to the potential problem is quite simple: you can disable the standard immobilizer yourself. It is worth considering that this is recommended only in cases where your VAZ-2115 already has an alternative anti-theft system installed, otherwise you will simply give the green light to attackers.

So, in order to deactivate APS-4 without self-flashing and provide unhindered access to the engine, you need to do two things: completely dismantle the immobilizer itself and erase the security coding data from the memory of the car’s electronic control unit. This procedure must be carried out carefully: there is a risk that the system will regard this intervention as an attempt to steal a car and block further access.

This method is fast, simple and convenient, but, unfortunately, it cannot absolutely guarantee that you will disable the built-in factory protection system. If this procedure does not help, intervention in the electronic system will be required - flashing, which is still better to entrust to specialists, since careless actions can block not only the engine, but also the entire control system as a whole. Take care of the safety of your car in advance - and it will serve you as long as you want.

Ways to turn off the alarm

If after the above diagnostics the problem is still not solved, you need to turn off the alarm manually. First of all, under the hood you need to find where to install the alarm. After this, de-energize the contacts of the speaker emitting the siren.

It is better to hide the Valet button not in the most obvious place. Photo: car-key.by

The alarm can be turned off using a special hidden button located in the car interior, under the instrument panel. It's called Valet. The rules for using this button can be specified in the instructions supplied by the car alarm manufacturer. If it is missing, then after detecting the button, you need to carry out the following actions:

• Turn on the ignition, quickly press the button and turn off the ignition;
• Turn on the ignition, quickly press the button four times and turn off the ignition;

If there is an alarm system with a GSM communication standard, you must read the instructions, which indicate instructions for entering a PIN code. After its introduction, the vehicle starts and the alarm loudspeaker is connected.

In any case, try to act according to the instructions that came with the alarm.

Below we will tell you how to deal with the most common alarms.

Bottom line

Despite the variety of existing manufacturers and models of car alarms, their maintenance and repair are almost the same. It is important to know where in the car the Valet alarm service button is located. With its help, you can turn off a faulty alarm yourself. Therefore, it is important to know the features of switching to the service mode of a particular model of car security system.

Have you often had to stand for a long time and press the buttons on your car's alarm key fob because it wasn't working and you didn't know how to turn off the alarm? Or you came out of some place and realized that the car keys are there, but the key fob has disappeared somewhere. Of course, such situations do not happen so often, but they still happen, and let’s try to figure out what to do in this case.

In order to understand how to turn off the alarm, there are several options. Firstly, you can so that the signal does not work, or lower it a little, after which the wire that leads to the transmitter is carefully cut. Another way to disable the alarm is to use a stun gun. To do this, it is necessary to fire several discharges onto the glass so that they act on the transmitter that is attached to it. You can also create noise interference by using special devices. First, the operating frequency of the transmitter itself is determined, and then it is subjected to noise.

Without a keychain, not everyone knows, so it’s worth looking into everything in detail. At the first stage, you should turn off the siren so that it does not irritate others. In case you have car keys, you can open the hood, find the place where the siren itself is located, and cut the wires. The bell is filled with polyurethane foam, but this is the case when the siren operates autonomously. If you don’t have foam at hand, you can use a hammer and hit it hard, of course, it’s a pity, but what to do? But how to turn off the alarm if there are no keys? To do this, you need to look under the car, that is, lie on the ground and find the siren and break the wire that goes to it.

When the first stage is finished, the flashing lights will stop and all that remains is the flashing lights. Now let's start looking for the main alarm unit. It can be found by the clear clicks that the relay makes. In most cases, this procedure must be carried out on those cars where an injector or immobilizer is installed. One of the best options for how to turn off the alarm in a car is that you know exactly what alarm is installed, or you have a printout where the colors and numbers of the wires are clearly indicated.

There are different ways of interlocking: it can be made on a closed relay, on an open relay, based on a LAN bus, or even built-in. In the first case, you can simply break the wires, thereby de-energizing the relay. In the second, it is necessary to ground one of the wires; for this, a jumper is installed. The next type of blocking can be removed by bridging the two wires that enter the block.

On a car with carburetors, you don’t even have to look for the location of the locks; in order to start the car, you need to connect the positive terminals of the battery and on diesel engines with electric valves, you need to connect the positive terminal of the battery and the valve output to the fuel injection pump. Thus, it turns out that in order to start the engine, you just need to apply voltage to the wire

Your alarm is disabled, have a nice trip!

An alarm system is an integral part of a modern car. It allows you to ensure security at the proper level. In most cases, it is beneficial, but there are times when the operation of the security device is disrupted, and the question arises: how to turn off the car alarm completely so that the engine starts, or stop the noise that arises from it, but the key fob does not work?

Often the driver cannot turn off the alarm for the following reasons:

1. The battery in the key fob is dead.
2. The key fob is out of order.
3. A lot of radio interference.

Please note that if the alarm is blocking the doors, you will need to call a specialist.

It is not often that a security device does not respond to control. However, there is a danger of blocking in the world. The reasons may be different. As for the alarm system, if you have a key fob, you should check:

1. The batteries that are inside.
2. Car battery.
3. Interference from surrounding radio devices.

As for the batteries, everything is simple. The display has an indicator that shows the charge. If it is at zero or close to it, then you need to look for a new power device. Fortunately, in cities there are no problems with this. It should be taken into account that the battery could not only run out, but become deformed. In this case, you may have to not only change the battery, but also clean the contacts before that if the old one “starts to leak.”

If the battery in the car is dead, you need to open the doors and immediately turn off the alarm. Next comes turning off the sound signal and solving problems with the battery.

As for interference, it often occurs in parking lots. A high concentration of vehicles with security devices may affect signal quality. The solution to the problem is to bring the key fob as close to the control unit as possible. The latter, as a rule, is located closer to the driver.

Having solved these problems, the driver enters the cabin. Then option 2: either everything is fine and you don’t need to disable anything, or you have to use the service key.

If the car door is open, then there is a problem starting the engine. After all, most modern security systems block it. The steps are as follows:

1. Turn off the alarm speaker.
2. Start unlocking the engine.

It will take some time to unlock the motor. Therefore, you will have to crawl under the hood and turn off the alarm speaker.

To disable the security device you will need:

1. Perform the ignition switch combination.
2. Press the secret key Valet.

Installation location of the service button:

1. Shows the specialist who was involved in the installation of security systems.
2. You should check with the previous owner of the car if it was purchased secondhand.

An independent search, if the location is unknown, is carried out at random in the following places:

1. Under the car dashboard.
2. Near the fuse box.
3. Near the control pedal.

Different manufacturers of car security systems use different combinations to put the device into service mode. The combination for Pantera, Sheriff, Alligator security systems is not complicated:

1. Turn on the ignition.
2. Press Valet for a short time.
3. On some Pantera systems, the button must be held for several seconds.

How to turn off the Starline alarm using a button:

1. Turn on the ignition.
2. Press the Valet button for models A1, A2, A4.
3. For models A8, A9, the button should be pressed 4 times.
4. Turn off the ignition.

The StarLine A6 system requires a more complex combination. To operate this device, a two-digit code is used, and it indicates the number of presses.

Example for code 11 (factory default code):

1. Turn on the ignition.
2. Press the service button once.
3. Turn off the ignition.
4. Turn the ignition back on.
5. Press the button again.
6. Turn it off again.

There are other systems that also use a two-digit code. By following the steps described above, you can unlock the engine.

Another situation: the driver has turned off the alarm, but the car does not start. In this case, the engine blocks the electrical equipment. It may malfunction during its operation. And the severity of the problem does not depend on the car, but on the complexity of the anti-theft complex.

Signs of blocking:

• The engine won't start.
• The power plant stalls immediately after starting.
• There is no response to starting from the key fob.
• Does not respond to the ignition system.

Troubleshooting steps:

1. Study the pictograms on the electronic system control panel. Additional functions are often activated.
2. Check the LED light, if present. If it flashes, it means the anti-theft system is activated in the menu.

If there is an “immo” inscription on the control panel, then the following actions should be taken:

1. Remove the key from the ignition. Open the central lock using the key fob.
2. Get out of the car, turn on the security system, turn it off and try to start the engine.

If there are no signs of intentional blocking, you should use the service mode. To do this, you should perform an operation with the Valet button. Please note that you need to hold the emergency button to turn off the alarm for 10 to 20 seconds. In this case, the signal LED should light up and then go out. After the light goes out, you can try to start the engine. After the problem is resolved, you need to enable the security function again.

How to turn off the alarm on a car without a key fob

If the problem cannot be resolved using a new battery in the key fob, use the methods suggested below.

Disabling using the Valet button

If your remote control does not work even with new batteries, use the coded or emergency power-off method. First of all, you need to find out the location of the service button in the car. “Valet” allows you to activate the setup mode and turn off the device if necessary.

You can find out the location of the device in the technical documentation, or ask the employees who installed the security system on your car.

When you press the “Valet” button, the alarm is turned off and the driver is given the opportunity to drive to the service center

Basically, the button is hidden in the dashboard area, in the glove compartment, or near the pedals.

Emergency shutdown

To implement this method, certain actions must be followed in a given sequence. The main steps vary depending on the manufacturer of the alarm; basically, you need to turn the ignition key to the “ON/OFF” position several times and quickly press the service button a certain number of times.

If there is no technical documentation for the signaling, you will have to look for the button yourself. We advise you to muffle the sound of the alarm by removing the terminals: this will make it more comfortable for you to carry out all other manipulations, and you will not attract the attention of passers-by.

How to disconnect from power

The method of turning off the alarm without a service button involves working with wires. The action includes the following steps:

• We find the signaling unit, which is located under the torpedo;
• Pull out all the wires;
• We are trying to start the car.

The alarm unit is located under the front panel of the car

If the above actions turn off the signal, but the car still does not start, most likely, your security system additionally blocks the starter, fuel pump and other components. Next we proceed according to the following scheme:

• We inspect the main vehicle wiring to which the wires from the security system are connected;
• The presence of a blockage is indicated by a cut standard wire, to the ends of which devices for remote control from the key fob are connected;
• Disconnect the alarm wires and connect the cut parts of the wire;
• If this does not affect the operation of the engine in any way, and it still does not start, we look for other cuts that may indicate the presence of additional blockages.

Before performing all manipulations, be sure to disconnect the terminals from the car battery.

Disabling in a coded way

This method is implemented using a password that the owner comes up with independently. It can include from 2 to 4 digits. To deactivate the security system using this method, you must follow the following sequence of actions:

• We get inside the car by opening it with the key;
• Turn the key in the ignition;
• Quickly click on the service button the number of times that corresponds to the first digit in your code;
• Turn the key in the ignition to the reverse position;
• These steps must be repeated with other numbers of your personal code.

To prevent annoying squeaking from confusing you, it is advisable to remove the terminals from the battery before performing any work.

How to turn off a car alarm

There are few things more embarrassing (or more annoying if it's your neighbor's car) than a car alarm that won't turn off. There are a number of reasons why a car alarm won't turn off, and a few different methods you can use to silence the squealing noise—and put an end to the embarrassment.

Part 1 of 1: Turning off the car alarm

Necessary materials

Step 1: Familiarize yourself with the alarm . Although it may not seem like an ideal time to read the owner's manual, many times the problem is user error. Make sure you follow the correct procedure to turn off the alarm.

Step 2: Start the car . Insert the key into the ignition and try to start the car. Almost all alarms, both factory installed and aftermarket systems, are disabled and reset when the vehicle is started.

Step 3: Use your key to unlock the driver's door . This will usually turn off and reset the alarm. If the driver's side door is already unlocked, lock the door and then open it again.

Step 4: Pull out the fuse . A factory installed alarm will have a fuse in the fuse box; Pull the fuse to turn off the circuit and turn off the alarm.

Locate the fuse box on the left side of the steering column. Fuse boxes usually have a fuse diagram on the fuse box cover.

Most fuses have a warning label. If the fuse is not labeled, refer to your owner's manual to determine the location of the fuse.

• Tip : Some vehicles have multiple fuse boxes - refer to your owner's manual for the location of the different fuse boxes.

Remove the fuse. If the alarm goes off, you have pulled out the correct fuse. If the alarm does not go off, reset the fuse and try another until you find the right fuse.

After the alarm goes off, reset the fuse and see if that resets the system. If the alarm goes off again, it's time to get a professional to repair it.

If the alarm system is an aftermarket item, locate the fuse in the engine compartment. Consult your owner's manual if you cannot find the fuse.

Step 5: Disconnect the battery . This is a last resort as it resets all electrical systems in the car and your car will not start until the battery is reconnected.

Disconnect the negative terminal (black) from the battery. The alarm should turn off immediately.

Wait a minute or two and reconnect the battery. Hopefully the alarm is cleared and won't start again. If so, try disconnecting the battery cable again.

• Tip : If this does not help, leave the battery cable disconnected and have the system repaired by a mechanic or alarm installer.

Step 6: Support your keychain . Most modern cars use a key fob to lock and unlock your doors and disable your alarm. Unfortunately, the key fob will not work if the batteries are low or simply not working.

Hopefully, if you tried the steps above, the alarm has stopped and all the dirty looks from your neighbors have stopped. If it was necessary to disconnect the battery to disable the alarm, a professional mechanic, such as one from YourMechanic, should inspect the entire system to ensure everything is working properly.
