Diagnostics & Security
Keys, Immobilisers & Alarms
Car won't recognise the key? Immobiliser faults, remote and key programming, alarms and gear locks.

When the immobiliser won't let the engine start, you need someone who understands both the electronics and the car. We diagnose immobiliser and keyless-entry faults, program replacement remotes and transponder keys for many makes, and repair or fit alarm systems.
We ask for proof of ownership before any key or immobiliser work – for your security and ours.
What’s included
- Immobiliser fault diagnosis
- Remote & transponder key programming
- Remote battery & casing replacement
- Alarm repairs & installation
- Central locking integration
Signs you need this
Key not detected / immobiliser

Try the spare key first – if it works, the problem is the key. Keep both keys with you for our technician.
