Transponder Chip

A small electronic chip, also known as transponder, is incorporated inside the head portion of your car keys. This technology was first introduced in vehicles manufactured after 1995. Also known as a chip key' or a 'transmitter and responder' key, it is created to stop the engine from starting if someone else has a copy of your car key. It works by sending an audio signal from the key to your immobiliser system. If the code on the car's computer matches that signal sent from the key, it will disarm the immobiliser and allow the engine to begin.

The key with a transponder is also called a "fob" or a "smart" key due to the fact that it is more difficult to duplicate than a mechanical key. It is possible to duplicate a conventional key, but not a transponder one. Transponder chips are powered by an infrared signal not battery power.

To activate the transponder chip the ignition cylinder needs to be turned to the ON position. The ring emits a burst IR energy which is picked up by a microchip within the key. The chip responds by sending a unique code the immobiliser of your car. The car's computer checks the code stored in its memory with the one from the transponder chip and when they match the engine will be able to start.

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

If the system is unable to identify a digital serial number from the chip in your key it will disengage the engine immobiliser and prevent the car from starting.

The car immobiliser system is an effective in stopping thieves, however it can be out of sync with the key or transponder chip. This could be due interference or the system is too sensitive. If this is the situation, it might need to be reset. To do this, simply disconnect the battery. It should be left disconnected for around 15 minutes before reinstalling it and start the car. This will reset the system and allow it to accept the key again.

The security light is the car immobiliser's method of letting you know that there is a problem with the system. If you attempt to start the car but the light stays on, it indicates that the chip inside your key isn't compatible with the code stored in the ECU. This can happen if your car key was replaced with a new one that is not programmed for the vehicle, or when an ECU was not swapped correctly.

This should solve the issue if you repeat it three times.

Programming

Modern cars come with this system as standard. This makes it extremely difficult to connect the car to a hot wire or use a different key as a starter. The system works by checking the chip in a key fob or key, and transmitting a passcode to the ECU (electronic control unit). The ECU knows it's the correct key and that it doesn't have to be compromised code. The system won't allow the vehicle to start if it does not receive the correct code. Some models will even report back to the owner if someone tries to use an incorrect fob or key.

The system isn't completely 100% secure, however. Some thieves have managed to bypass the immobiliser using techniques like 'hot-wiring'. This involves crossing the wrong wiring in a vehicle to trick the ECU. But, this technique is quite dangerous and requires a lot of experience in order to carry out the procedure without electrocuting yourself. Plus, a lot of modern car thieves have shifted to more sophisticated methods, such as using specialized apps or Bluetooth to hijack a car's data and remotely control it via their mobile.

Car owners are often faced with warning lights that indicate the immobiliser is malfunctioning. This can occur for a variety of reasons however the most common one is a faulty battery in the keyfob. The issue can be solved by replacing the battery.
