Immobiliser Installation in Portsmouth and Hampshire
Car immobilisers are one of the most effective ways to prevent someone from driving off with your vehicle. These clever security devices see to it that your car will only start if someone has inserted the correct key into the ignition. That means a would-be thief cannot make off with your car by hot-wiring it. Here at TCM Automotive, we have a range of car immobilisers to suit any make or model, all fitted by our team of expert technicians.

Frequently Asked Questions
Older factory immobilisers can be vulnerable to key-cloning and relay attacks, but a modern aftermarket immobiliser closes that gap. The systems we fit require a unique sequence to be entered before the engine will start, which can't be defeated by cloning a key or hacking keyless entry. This makes the car extremely difficult to drive away even if a thief gets inside.
Yes, that's exactly what it's built to do. An immobiliser blocks the engine, fuel or ignition circuits so the car won't start until the correct code or key is recognised. Without that authorisation the vehicle simply won't move, which is what makes it such a strong deterrent.
Most cars built from the late 1990s onwards left the factory with a basic immobiliser, but these standard systems vary a lot in how much protection they actually offer. Many modern keyless models are now targeted through relay theft that a factory system can't prevent. Fitting an additional aftermarket immobiliser is a reliable way to protect these vehicles.
The right system depends on your vehicle, how you use it and the level of protection you want. We fit CAN bus immobilisers that integrate with the car's own electronics and need a personal PIN-style sequence to start, giving strong protection against relay and key theft. Our Portsmouth team can recommend the best option once we know your make and model.
If an immobiliser develops a fault, the car may refuse to start or show a warning even when you're using the correct key. This is usually down to a wiring issue, a faulty sensor or a flat key fob battery rather than the whole unit failing. Our technicians diagnose the actual cause and get you moving again rather than replacing parts unnecessarily.
For anyone with a keyless car or a commonly targeted model, an immobiliser is one of the most effective security upgrades available. It stops the car being driven away even if a thief gets inside, and many insurers look favourably on a professionally fitted system. Drivers across Portsmouth and Hampshire fit one for exactly that reason.
