Description
Overview
Complete immobilizer and remote set designed for Citroën C1 and Peugeot 107. This kit combines the immobilizer unit, central locking control and one transponder key fob that were synchronized together on a donor vehicle. Ideal for professional garages and experienced DIY mechanics who need a matched set with known part numbers for straightforward replacement and programming.
What The Kit Contains
The package includes an immobilizer unit, central locking module and 1x key fob with an integrated transponder chip. The components are pre-paired from one vehicle to ensure internal compatibility; however, vehicle-specific ECU and immobilizer data must be programmed to your car before the engine will start.
Fitment & Compatibility
Intended for Citroën C1 and Peugeot 107 models. Commonly referenced by the original part numbers listed below, this assembly is often searched for by part code when sourcing replacement electronics for PSA small city cars.
Installation & Programming
Mechanical installation is typically a direct swap of connectors and mounting points, but correct function requires electronic programming. Recommended steps for installation:
- Disconnect the vehicle battery before starting work to avoid short circuits.
- Access the existing immobilizer/cental locking unit (location varies by model; often under dash or steering column).
- Replace the unit and connect all harnesses securely.
- Use a diagnostic or key programming tool to transfer or program immobilizer data and to pair the supplied key fob with the vehicle ECU and immobilizer system. Dealer-level or professional locksmith equipment (e.g., DiagBox/PP2000, Lexia or equivalent) may be required.
Note: Without proper programming the engine control unit will not recognize the transponder and the vehicle will not start. If you are not experienced with ECU/immobilizer coding, seek assistance from a qualified technician or locksmith.
Common Failure Modes & Maintenance
Typical reasons for replacing an immobilizer or remote set include worn or damaged key fob buttons, internal electronic failure due to moisture or corrosion, water ingress into the unit, impact damage, or loss of key programming after an ECU replacement. Remote fob operation can also be affected by a weak internal battery; replace the battery if only range or button response is poor.
