Diagnose before replacing
Intermittent key recognition, immobiliser warnings and module communication faults need evidence, not guesswork. We test the system and explain the next useful step.
Key and remote
We assess key output and vehicle response so a healthy key is not replaced to mask a receiver, voltage or synchronisation problem.
Vehicle modules
Diagnostic equipment checks relevant module communication and fault information before coding, synchronisation or referral is recommended.
Our process
Pricing
Vehicle platform, fault complexity, required equipment, location and any follow-on coding affect the quote. We agree diagnostic attendance first and explain additional work separately.
Security and guarantee
Ownership checks apply before security programming. Completed coding and workmanship are covered by our 12-month guarantee within the confirmed scope.
Useful answers
No. Low voltage, receivers, wiring or module communication can create similar symptoms, which is why diagnosis comes first.
No. We explain what can be completed safely at the vehicle and when specialist bench repair or another trade is more appropriate.
If safe to do so, it is useful basic evidence—but changing a remote battery will not resolve every transponder or immobiliser fault.
Note the conditions, messages and timing. Videos and details about recent work can make an intermittent fault easier to isolate.
