Car Immobiliser Service: Keeping Your Vehicle Secure
A car immobiliser is an electronic security device that prevents your engine from starting unless the correct key or fob is present. It’s a crucial part of your vehicle’s anti-theft system, making it much harder for thieves to steal your car. Like any other system in your car, the immobiliser can experience issues and require servicing.

Understanding Your Car Immobiliser
Car immobilisers work by using a transponder chip embedded in your car key. This chip transmits a unique code to the vehicle’s immobiliser control unit when you try to start the engine. If the code is recognised, the immobiliser system disengages, allowing the engine to start. If the code is incorrect or missing, the immobiliser system will remain engaged, effectively preventing the engine from starting.
Common Car Immobiliser Problems
While immobilisers are generally reliable, they can encounter issues just like any other electronic component in your vehicle. Here are some common problems you might face:
- Key Fob Battery Issues: A dead battery in your key fob can prevent the immobiliser from disengaging, even with the correct key.
- Faulty Transponder Chip: The transponder chip in your key can become damaged or malfunction, preventing it from transmitting the correct code.
- Immobiliser Control Unit Problems: The control unit itself can malfunction due to electrical issues or software glitches, leading to immobiliser system failure.
- Wiring Problems: Damaged or corroded wiring can disrupt communication between the key, the control unit, and the engine, causing the immobiliser to malfunction.
