This chip sends a passcode to the car's immobilizer unit which can be integrated into the PCM, BCM, the instrument cluster, smart junction box or standalone module.

However, even vehicles equipped by the manufacturer with an immobiliser can experience issues with it. Fortunately, these problems are usually simple and inexpensive to solve. A dead or dying keyfob battery can be the cause of a faulty ignition immobiliser. This can be identified with an instant diagnostic test.

Transponder Chip

A tiny electronic chip, referred to as a transponder, is built in the head of your car keys. The technology was introduced in cars made after 1995. Also referred to as a 'chip key or a 'transmitter and responder key, it is designed to stop the engine from starting if a third party has a copy of your car key. It works by transmitting radio signals from the key to your immobiliser system. If the code on the car's computer matches that signal sent from the key, it will deactivate the immobiliser and allow the engine to start.

The key with the transponder chip is often referred to as a 'fob' or a "smart" key due to the fact that it is more difficult to duplicate than a conventional mechanical key. It is possible to duplicate a standard key but not a transponder one. In contrast to the central locking element remote of a conventional key, which is powered by batteries, a transponder chip powered by the infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.

To turn on the transponder, the ignition cylinder needs to be in the ON position. The ring emits a burst IR energy which is received by a microchip within the key. The chip then sends a unique code to the immobiliser inside your car. The car's computer analyzes the code stored in its memory to the one on the transponder and when the two codes match it will begin the engine.

The immobiliser will disable the engine when it detects an unauthorised transponder or key. It also stops all vital parts of the car from functioning.

If the system can't detect a serial number digital from the chip inside your key it will disengage the engine immobiliser and prevent the car from getting started.

This car immobiliser system is an effective way to stop thieves, but it is also possible for it to become out of in sync with the key or transponder chip. This could be due interference or a system that is too sensitive. If this is the case it might need to be reset. To do this, disconnect the battery. Then leave it off for around 15 minutes then reinsert it and start the car. This will reset the key system so that it is ready to accept your keys again.

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

If this is the case you should bring your transponder key or chip to a professional for them correctly programmed for the vehicle you are driving.

Programming


The car immobiliser prevents the engine from running if the fob or key is not properly programmed. It is based on a specific RFID microchip that cannot be duplicated and has its own digital serial number. The immobiliser will be disengaged in the event that it doesn't recognize the code. That's why it's difficult to defeat.

Modern cars have this system as standard. This makes it extremely difficult to wire the car hot or use a different key for starter. The system operates by sending a passcode from the key fob to the ECU. The ECU then knows that it's the correct key and that the code hasn't been compromised. The system will not allow the car to start if the doesn't have the correct code, and some models will even report back to the owner if a person tries to use an unapproved fob or key.

However, the system is not foolproof. Some thieves have managed to bypass the immobiliser by using techniques such as 'hot-wiring.' This involves crossing the wrong wire in a vehicle to fool the ECU. This is a risky method and requires a lot of experience to avoid electrocuting oneself. Modern car thieves are employing more sophisticated methods for instance, Bluetooth or other specialized apps to obtain information about a vehicle and remotely manage it.

Car owners often see warning lights that indicate the immobiliser has gone haywire. It can happen for various reasons, but the most common one is a faulty battery in the keyfob. A simple replacement can fix this problem.
