Peugeot/Citroen Immobilizer System

This description does not apply to Fiat-derived PSA vehicles. On the other hand it applies to Fiat Scudo (which is based on Peugeot Expert).

PSA-COM allows you to code keys in BSI control unit. PIN is required to code keys.

According to our knowledge PIN code is stored in BSI and Injection control unit. In order to re-use older ECU it is necessary to re-program pin code to match both ECUs.
