Compatibility and Application
The unit fits perfectly on Citroën C1 and Peugeot 107 models, making it an ideal replacement part for automechanics and DIY car repair enthusiasts alike. Engine control unit programming can be synchronized with your vehicle’s existing system to ensure proper function after installation.
Replacing the immobilizer unit usually requires disconnecting the battery and removing panels to access the central locking and engine control modules. Once installed, the system must be relearned or programmed using specialized diagnostic equipment or via a compatible vehicle-specific procedure to ensure correct operation.
Over time, immobilizer units may fail due to electronic faults or physical damage which cause communication issues with the engine control system, leading to immobilization problems or failure to start the vehicle. Replacing the unit restores secure engine start functionality.
