Most cars are equipped with an immobilizer system that stops car theft. If your vehicle won't start after inserting the key fob there could be an issue with the transponder chip not sending an authorization code to the immobilizer system.

The immobiliser is powered by a transponder that is located in the key, fob or instrument cluster. The chip transmits a passcode from the key or fob to the immobilizer module of the car, which can be integrated into the PCM (power control module), BCM (brake control module for brake control) instrument cluster, smart junction boxes, or standalone modules. The system then validates the code to ensure that it is correct. If it is not then the system will disable components crucial to starting the vehicle, like the starter motor or ignition. This makes the car almost impossible to start if you don't have the right key.

However, even vehicles that were factory-fitted with an immobiliser could face problems with it. Fortunately, these issues are usually simple and inexpensive to repair.

Transponder Chip

In cars manufactured after 1995, a small electronic chip referred to a transponder is built into the head of your car key. It is also referred to a "chip key" or a "transmitter-responder" key. Its goal is to prevent the engine from starting when you have an identical key. It works by transmitting an audio frequency signal from the key fob repairs to the immobiliser system of your car. If the code in the car's computer is in line with the signal transmitted by the key, it will disable the immobiliser and allow the engine to start.

The key that has the transponder chip is often referred to as a 'fob' or a "smart" key because it is much more difficult to clone than a traditional mechanical key. It is possible to duplicate a traditional key but not a transponder key. Transponder chips are powered by an infrared signal and not battery power.

To activate the transponder, the ignition cylinder needs to be in the ON position. The ring emits a burst IR energy that is received by a microchip inside the key. The chip responds with an unique code to the immobiliser in your car. The car's computer compares the code in its memory to the one from the transponder chip, and if they match the engine will be able to start.

If the immobiliser detects that an unauthorised transponder or key is in use, it will disable the engine and prevent the essential components from working.

If the system is not able to recognize a digital serial number from the chip in your key, it will disable the engine immobiliser, which will stop the car starting.

The car immobiliser is an excellent method to deter thieves, however it can occasionally be out of in sync. This can be due to interference or the system being too sensitive. If this is the situation, it could be necessary to reset. To do this, just disconnect the battery. Leave it disconnected for about 15 minutes then reinsert it and start the Car key immobiliser repair (b.cari.com.my). This will reset the system and make it ready to accept the key again.

The security light is an immobiliser's way of alerting you to a problem. If you try to start your car and the light stays on it means that the chip inside your key isn't compatible with the code stored in the ECU. This can happen if you have recently replaced the car key with one that isn't programmed to the vehicle or in the event that you've had a defective swapped ECU.

If this is the case, it's best to take your transponder or key chip to a professional to get them properly programmed for your vehicle. It is possible that the system won't accept the key because of a software update or bug.

This should cause the security light to turn on and to turn off. If it doesn't then you must repeat the procedure and wait for another 10 minutes. Do this three times and the issue is likely to be solved.

Programming

A car immobiliser stops the engine of a car from running without a properly programmed key or fob. It uses a special RFID chip that is unable to be duplicated and has a unique digital serial number. The immobiliser will stop working if it doesn't recognise the code. That's why it's difficult to defeat.

Modern cars come with this security system in the standard configuration. This makes it extremely difficult to hot-wire a car or utilize a different key for starter. The system works by sending a passcode from the key fob to the ECU. The ECU will then verify that it's the correct key and that the code hasn't been compromised. The system won't allow the car to begin in the event that it does not receive the correct code. Certain models will even notify the owner if they attempt to use an incorrect fob or key.

The system isn't completely 100% secure, however. Some thieves have been able to bypass the immobiliser using methods such as 'hot-wiring'. This involves crossing the wrong wires within the wiring of a vehicle, which fools the ECU into thinking that the appropriate fob or key is being used. But, this technique is extremely dangerous and requires a lot of experience to accomplish it without damaging yourself. Modern car thieves are employing more sophisticated methods, such as Bluetooth or other specialized apps to steal a car's information and remotely control it.

Car owners will often get warning lights that signal that the immobiliser is malfunctioning. This can occur for a variety of reasons but the most frequent one is a malfunctioning battery in the keyfob. The issue can be solved by an easy replacement.

If this does not work it could be because the transponder chip may be defective or the ECU is mismatched. This is more difficult to determine and fix, broken car key repair as it can involve a specialist car locksmith or dealership. However, a car's immobiliser may also be damaged by water intrusion, or even being removed from the fob or key.
