Immobiliser & Module Repair in Sunbury-on-Thames — Repaired, Not Replaced
When a control module fails, the dealer fits a new one and charges for programming on top. We repair the original at component level in Sunbury-on-Thames — immobilisers, BSI units, airbag modules and more — so your car keeps its identity and you keep your money.
Why replacement isn’t your only option
As a riverside town, Sunbury-on-Thames generates a steady stream of work for us, and M3 junction 1 on the doorstep keeps travel times short. Same-day visits are often realistic — just ask when you call.
Modern cars are run by control modules — 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 — tracing the failure, replacing the faulty parts and repairing the board — 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 Sunbury-on-Thames anywhere from the centre to the TW16 outskirts, and it’s typically a fraction of the cost of replacement.
Because we repair the original unit, there’s no recoding and no immobiliser re-sync — the car keeps its identity and just works again.

Immobiliser & Module Repair in Sunbury-on-Thames — your questions answered
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 — far cheaper than a new unit, and done without main-dealer programming.
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 — 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 — 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.
How quickly can you get to Sunbury-on-Thames?
Usually very quickly — Sunbury-on-Thames sits close to M3 junction 1, and we’re in the area regularly. Same-day appointments are often available; call and we’ll give you an honest arrival window.
Will the repair keep my keys and coding working?
Yes — because we repair your original module rather than fitting a new one, your keys, coding and immobiliser data all stay exactly as they were.
