Description
Product Overview
This delivery contains an immobilizer unit with remote control and one transponder key, together with the matched engine control module. All items were removed as a matched set from a Peugeot 107 (2007), ensuring correct pairing of immobilizer, remote and ECU.
Function And Benefits
The immobilizer prevents engine start unless a programmed transponder key is present. The included remote provides central locking and remote unlock convenience. Supplying the immobilizer together with the matched ECU and key reduces programming complexity and helps restore full vehicle security and convenience.
Installation And Programming
Replacement requires basic mechanical access and a diagnostic/programming step. Typical procedure: disconnect the battery, remove interior trim to access the immobilizer/ECU location, fit the new unit and secure connections. Final step: program the transponder key and sync the immobilizer with the ECU using a compatible PSA diagnostic tool such as DiagBox/Lexia or an aftermarket key programmer that supports PSA vehicles. Professional programming is recommended for reliable synchronization.
Common Failure Causes
Immobilizer systems and remotes can fail due to moisture ingress, corrosion, physical damage to the key or circuit board, wiring faults, battery issues in the remote, or electronic faults following collisions or voltage spikes. Replacing both the immobilizer and related ECU/key as a matched set avoids many diagnostic pitfalls.
