Immobiliser, BSI & Airbag Module Repair in Dorking
A dead immobiliser or a faulty control module can strand a perfectly good car. We diagnose and repair these units at board level across Dorking, mobile, and far cheaper than replacement.
Immobiliser & module repair in Dorking
As a market town, Dorking generates a steady stream of work for us, and the A24 on the doorstep keeps travel times short. Same-day visits are often realistic β just ask when you call.
Modern cars are run by control modules β the immobiliser that lets the engine start, the BSI or body-control unit that manages the electrics, the airbag/SRS module, comfort and convenience units. When one fails, the dealer’s only answer is a new module plus programming to marry it to your car, which gets expensive fast.
Most of these faults are repairable. We work at component level β tracing the failure, replacing the faulty parts and repairing the board β so your original module goes back keeping its coding and immobiliser data intact. No new unit, no reprogramming, no drama.
It’s done mobile or on a collect-and-return basis across Dorking across all RH4 and RH5 addresses, and it’s typically a fraction of the cost of replacement.
BSI and body-control faults throw the weirdest symptoms β random warning lights, flat batteries, electrics with a mind of their own β and they’re often very repairable once properly diagnosed.
Many customers book us for more than one thing at once: we also provide ECU cloning, car diagnostics and instrument cluster repair across Dorking.

Immobiliser & Module Repair in Dorking β your questions answered
Where do you carry out the work in Dorking?
Wherever your car is β your driveway, your street or your workplace car park anywhere in Dorking. All we need is safe access to the vehicle.
Will the repair keep my keys and coding working?
Yes β because we repair your original module rather than fitting a new one, your keys, coding and immobiliser data all stay exactly as they were.
Which makes do you cover?
Most major manufacturers. Give us the make, model and a description of the fault and we’ll tell you straight away whether we can help.
Why repair a module instead of replacing it?
A repair keeps your original unit and its coding, so there’s nothing to reprogram and no immobiliser re-sync β and it’s typically a fraction of the cost of a dealer replacement fitted and coded.
My car won’t start and I’ve been told it’s the immobiliser β can you help?
Very often, yes. A no-start with everything else working is frequently a repairable fault in the immobiliser or its communication with the ECU, rather than a reason to replace expensive parts. We diagnose it properly first, then repair the original unit.
