Immobiliser Repair: Restoring Start Authorisation
When the car no longer starts and the immobiliser blocks it, fast help is needed. We restore the original state: program keys, transfer immobiliser data and re-establish start authorisation at the control unit in Bench/Boot mode via pinning — often on the same day.
Keys & immo
Key learning, immobiliser matching and restoring start authorisation.
A safe process
Professional equipment for stable, traceable results.
Typical situations
Control unit replaced
After swapping the engine or immobiliser ECU the start authorisation is missing. We transfer the immobiliser data onto the new component.
Key not recognised
Defective transponder, antenna or reader unit? We check the full chain and program the key again.
Component protection active
A used control unit refuses to work because the vehicle network does not match. We restore the matching correctly.
Data lost after failure
Water damage or a memory fault in the immobiliser module: we recover the data and write it to a donor unit.
Scope of service
We restore:
- • Start authorisation after a control unit swap
- • Key and transponder matching
- • Immobiliser and EEPROM data on replacement parts
- • Component protection matching in the vehicle network
Not offered:
- • Disabling immobiliser functions
- • Odometer manipulation
- • Work on vehicles without proof of ownership
Proof of ownership required
We work on immobilisers and keys only for the registered vehicle owner. Please have the vehicle registration document and a photo ID ready. This protects both you and us and is standard practice for reputable key services.
