Immobilisers, alarms & central locking
A car that won’t recognise its own key, an alarm going off for no reason, or central locking that’s stopped working on one door — all fixable, usually faster than you’d expect.
Signs you need this
- Car won’t start even though the key looks fine
- Alarm triggers randomly, including overnight
- Central locking works on some doors but not others
- Remote key fob has stopped working or has a dead battery
- Aftermarket alarm was fitted badly and causes other electrical issues
What we do
We check whether an immobiliser fault is the key’s transponder, the vehicle’s receiver, or a wiring fault between them, rather than assuming it’s always the key. Central locking faults are traced to the specific door actuator or wiring run causing the issue.
What it costs
Cost depends on what’s actually faulty — a key or fob issue is usually straightforward, a wiring fault takes more diagnosis. We’ll confirm price before doing any work.
