BMW X3 2017 — All Keys Lost | CAS4 Key Programming

BMW X3 2017 All Keys Lost Service

We were contacted by the owner of a 2017 BMW X3 after all vehicle keys had been lost. This vehicle is equipped with a CAS4 immobilizer system and a DME MEVD17.2 engine control unit, requiring specialized procedures to restore key functionality.

When all BMW keys are lost, replacing the mechanical key alone is not enough. The replacement key must be properly programmed and recognized by the vehicle’s immobilizer system to restore authorized engine starting.

BMW CAS4 and DME MEVD17.2 Programming Procedure

The work involved several important steps:
• CAS4 data reading — retrieving the necessary information from the vehicle’s access and immobilizer system.
• DME ISN reading — obtaining the ISN from the MEVD17.2 engine control unit for the required immobilizer authorization procedures.
• Data preparation — preparing the required information for the key programming process.
• New key programming — performing the key-learning procedure for the BMW immobilizer system.

After programming, the keys and vehicle starting functionality are checked to confirm proper operation.
