Take that ID number to your dealer and request your seven-digit SKC, along with the workshop code and importer number (all this information can be found in the upper-right corner of the Administration screen of the dealer's VAS 5051). Additional information about how to find the WSC and Importer Number can be found here.

Measure the car's battery voltage, it must be 12.5 V or higher.

Blocks - 08] Group 022 [Go!] The value in field 3 must be 1. If value is not 1, the key is not capable of being adapted to Immobilizer. You can check each key in this manner.

[Select] [17 - Instruments] [Meas. Blocks - 08] Group 024 [Go!] Any numbers displayed in fields 1-4 represent the time in minutes that must be counted down before the Immobilizer is unlocked.
