The immobiliser is powered by a transponder in the key, fob or instrument cluster. This chip sends a passcode to the immobilizer unit of the car which can be integrated into the PCM, BCM, the instrument cluster smart junction box or standalone module. The system then verifies the code to ensure that it is correct. If it is not then the system will disable elements that are crucial to the start of the vehicle, like the starter motor or ignition. The car will be impossible to start if you do not have the right key.

The immobiliser system has proven extremely effective in reducing car theft since its first introduction. Despite this, thieves are always looking for new ways to get around these security measures.

However, even cars equipped by the manufacturer with an immobiliser may experience problems with it. Fortunately, these problems are usually easy and cheap to repair. A dying or dead keyfob battery can be the reason for a malfunctioning ignition immobiliser.  car remote key repair  could uncover the problem. If the issue continues, it could be due to electrical issues or wiring issues. If this is the case, it's recommended to have a professional diagnose and repair the problem.

Transponder Chip

In cars manufactured after 1995, a small electronic chip called transponder is integrated into the head of your car key. Also known as a chip key or a 'transmitter & responder' key, it is created to stop the engine from starting if someone else has a copy of your car key. It works by transmitting a radio frequency signal from the key to the immobiliser system in your car. If the code stored in the car's computer matches the signal sent by the key the immobiliser will then be disarmed and the engine will start.

The key that has a transponder is also referred to as a "fob" or a "smart" key, because it is more difficult to duplicate than mechanical keys. It is possible to duplicate a traditional key, but not a transponder one. Transponder chips are powered by an infrared signal, not battery power.

To activate the transponder, the ignition cylinder needs to be in the ON position. The ring emits a flash of IR energy which is detected by the microchip inside the key. The chip responds by sending a unique code the immobiliser in your car. The computer in the car analyzes the code stored in its memory to the transponder's and if the two codes match it will begin the engine.

If the immobiliser detects an unauthorised transponder, key or other device is being used, it will disable the engine and stop the essential components from functioning. The car won't move when the engine isn't working. It's easy for criminals to wire it to drive away. This is a powerful way to deter criminals and is one of the main reasons why it's important to have your car's key immobiliser repaired when you spot a fault with it. If you don't fix it, the security light on your car will continue to flash and it will be difficult to start your engine.

Security Light

The immobiliser makes use of a tiny battery to send an electrical signal to the chip inside your key. It is an anti-theft device that stops anyone from opening your car without the correct key. If the system is unable to identify a digital serial number from the chip in your key it will disengage the engine immobiliser, preventing the car from getting started.

The car immobiliser is a great method to deter thieves, however it can occasionally be out of sync. This could be due to interference or the system being too sensitive. If this is the situation, it could be necessary to reset. To do this, simply disconnect the battery. After 15 minutes, reinstall the battery and then restart the vehicle. This will reset the key system to ensure that it is ready to accept your keys once again.

The security light is the vehicle immobiliser's method of letting you know that there's an issue with the system. If you try to start the car and the light is solid on it indicates that the chip inside your key doesn't match the code stored in the ECU. This could happen if you have recently replaced the car key with another that has not been programmed to your vehicle or if you've had a bad swapped ECU.

If this is the case, then it's time to talk to a professional to have the key or the transponder chip properly programmed to your vehicle. It's possible that the system isn't able to accept the key because of a software update or glitch. To test, put your key into the ignition and turn the ON position. Don't try to start the car. The key should remain in this position for 10 minutes. The security light should come on, and then go off. If it doesn't then you'll need to repeat the procedure and wait another 10 minutes. This should solve the issue If you repeat the procedure three times.

Programming

An immobiliser for cars prevents a car's engine from running without a correctly programmed key or fob. It makes use of a unique RFID micro-chip that can't be duplicated and comes with its own serial number. The immobiliser will stop working when it is unable to recognize the code. That's why it's difficult to beat.

Modern cars come with this system as standard. This makes it very difficult to hot-wire a car or use a different key for starter. The system works by checking the chip in the key fob or key and sending a passcode back to the ECU (electronic control unit). The ECU will then verify that it's the right key and that the code hasn't been compromised. The system will not allow the car to begin in the event that it does not receive the correct code. Some models even notify the owner when they attempt to use a wrong fob or key.

However it isn't impervious to theft. Some thieves have bypassed the immobiliser by using techniques such as 'hot-wiring.' This involves using the wrong wiring in an automobile to fool the ECU. But, this technique is extremely risky and requires a lot of experience to do it without damaging yourself. Modern car thieves are employing more sophisticated methods, for instance, Bluetooth or other specialized apps to obtain information about a vehicle and remotely control it.

Car owners are often faced with warning lights that indicate the immobiliser has gone off the rails. This could be due to a variety of reasons, but the most common one is a malfunctioning battery in the keyfob. The issue can be solved by a simple replacement.

If this doesn't work the transponder chip could be defective or not compatible with the ECU. This is harder to fix and diagnose as it may require a professional locksmith or dealership. However, a car immobiliser may be damaged by water ingress or even physically being removed from the fob or key. If you experience any of these issues, it is a good idea that you visit the local car dealer or garage to seek help.
