The chip transmits a passcode to the immobilizer unit of the car, which may be built into the PCM, BCM, the instrument cluster, smart junction box or standalone module. The system checks the code to ensure that it is correct. If it’s not then the system will disable elements that are crucial to the start of the vehicle, such as the ignition or starter motor.

Transponder Chip

A tiny electronic chip, also known as a transponder, is built in the head of your car keys. This technology was introduced in cars manufactured after 1995. It is also referred to a “chip key” or a “transmitter-responder” key. Its function is to prevent your engine from starting when someone else has the same key. It works by sending radio signals from the key to your immobiliser. If the code stored in the car’s computer matches the signal transmitted by the key the immobiliser will be disarmed and the engine will start.

The key that is equipped with a transponder chip is often referred to as a ‘fob’ or a ‘smart’ key because it is more difficult to clone than a conventional mechanical key. It is possible to duplicate a standard key but not a transponder one. Contrary to the central locking element remote of a conventional key which uses battery power, a transponder chip is powered by an infrared (IR) signal transmitted by the antenna ring on the ignition cylinder.

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

The immobiliser will shut down the engine if it detects an unauthorised key or transponder. It also blocks any vital parts of the car from functioning. The car won’t move when the engine isn’t functioning. It would be easy for a criminal to hot-wire it and then drive off. This is a powerful way to deter crime, and is one of the main reasons why it is essential to get your car key immobiliser repaired immediately you discover any issue with it. If you don’t do this, the security light on your car will keep flashing and it will be inaccessible for you to start your engine.

Security Light

The immobiliser is powered by a tiny battery that sends an electric signal to the transponder chip inside your key. This device is designed to prevent anyone from starting their car without the correct keys. If the system can’t identify a digital serial number from the chip inside your key it will disengage the engine immobiliser and stop the car from starting.

This system for car immobilisation is an an effective way to stop thieves but sometimes it can get out of in sync with the key or the transponder chip. This could be due to interference or a system that is too sensitive. If this is the case, it might need to be reset. To do this, just disconnect the battery. After 15 minutes, reinstall the battery and then restart the car. This will reset the key system, so that it is ready to accept keys once more.

The security light is the car immobiliser’s method of letting you know that there’s an issue with the system. If you try to start the car but the light is solid on it means that the chip inside your key doesn’t match the code that is stored in the ECU. This could happen if your car key has been replaced by a new key that’s not programmed to work with the vehicle, or if the ECU was not swapped correctly.

If this is the situation, then it’s time to go to a professional for assistance and get the key or the transponder chip properly programmed to your vehicle. There is also the possibility that the system is not accepting the key due to an issue with the software or an update. To test this, put your key in the ignition and turn it to ON but don’t try to start the engine. Let the key stay in this position for ten minutes. The security light should come on, then go off. If it doesn’t then you must repeat the procedure and wait for another 10 minutes. This should resolve the issue If you repeat the procedure three times.

Programming

The car immobiliser stops the engine from running if the fob or key are not programmed correctly. It is based on a specific RFID microchip that isn’t able to be copied and has its own digital serial number. The immobiliser will be disconnected when it doesn’t recognize the code. That’s why it’s so difficult to defeat.

Modern cars come with this security system as standard. This makes it extremely difficult to wire the car hot or use another 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 right key and that the passcode isn’t compromised. The system won’t allow the car to start if 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 using methods such as ‘hot wiring.’ This involves crossing the wrong wire in an automobile to trick the ECU. This is a risky method and requires extensive experience to avoid electrocuting oneself. Modern car thieves are also employing more sophisticated methods, for instance, Bluetooth or other apps that obtain information about a vehicle and remotely control it remotely.

Car owners are often faced with warning lights that signal that the immobiliser is malfunctioning. This could be due to a variety of reasons, but the most common is a dead or defective battery on the key fob. This problem can be fixed by replacing the battery.

If this doesn’t work it could be because the transponder chip is faulty or the ECU is not matched. This is more complicated to fix and diagnose because it requires an expert car locksmith or dealership. The car immobiliser could also be damaged if water is able to get into the system or if it is physically removed from its fob or key. If any of these issues occur it’s a good idea to visit the nearest garage or dealer to seek assistance.
