Professional Vehicle Diagnostics London | Engine, Immobiliser & ABS Faults
Keylux carries out thorough diagnostic assessments for drivers dealing with warning lights, starting problems, or unusual vehicle behaviour. From immobiliser lockouts to ABS sensor faults and engine management errors, our mobile technicians read the fault codes and advise on the most effective next step.
Engine Management Diagnostics
A flashing or steady engine warning light doesn't always mean major repair work. We connect diagnostic equipment to read stored fault codes and identify what's triggering the alert.
Immobiliser Fault Diagnosis
If your vehicle won't start or the immobiliser light stays on, we investigate whether the issue lies with the key, the transponder chip, or the vehicle's security module, and advise on the correct fix.
ABS & Brake System Scanning
An illuminated ABS light can point to sensor, wiring, or module faults. We scan the system to locate the source and let you know whether it's a minor fix or needs specialist attention.
Dashboard Warning Light Checks
Cracked confidence in your dashboard alerts? We interpret warning symbols and stored codes so you understand exactly what's happening under the bonnet.
General Fault Code Reading
Sometimes a quick scan is all it takes to clear up confusion. Our technicians assess the codes carefully before recommending repair, reset, or further garage investigation, helping you avoid guesswork.
