Frequently Asked Questions

My car alarm keeps going off for no reason — can you stop it?

Yes. False alarms are usually a faulty sensor, a failing bonnet or door switch, or a low battery. We trace the trigger and repair it so you get some peace and quiet.

The immobiliser won't let my car start — can you help?

We diagnose immobiliser faults regularly. It may be a worn key transponder or a fault in the reader. We'll identify the cause and the most cost-effective fix.

Can you install an alarm on an older car?

Absolutely. We fit quality aftermarket alarms and immobilisers to older vehicles to bring their security up to modern standards.
