Car Won’t Start in Addlestone? Immobiliser & Module Specialists
Mobile immobiliser and module repair across Addlestone. From cars that won’t start to comfort and airbag modules playing up, we fix the electronics rather than throwing expensive dealer parts at them.
Immobiliser & module repair in Addlestone
Ask us where we work most and Addlestone is always near the top of the list. Access via M25 junction 11 and the A317 makes it a quick trip, and with Weybridge and Chertsey on the same run, same-day slots come up regularly.
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 Addlestone across all KT15 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.

Immobiliser & Module Repair in Addlestone β your questions answered
Where do you carry out the work in Addlestone?
Wherever your car is β your driveway, your street or your workplace car park anywhere in Addlestone. All we need is safe access to the vehicle.
Can you reset an airbag module after an accident?
Yes. After a crash the airbag/SRS module usually stores crash data and lights the airbag warning. We can reset the module so the light clears β far cheaper than a new unit, and done without main-dealer programming.
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.
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.
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.
