1999-2002 Cabrio with Immobilizer 2 – Key Adaptation and
Part Number
March 21, 2014: Update to Information.
If new keys cannot be adapted, they may possibly be the incorrect part number. Cabrio is equipped with
two generations (Gen2 and Gen3) of Immobilizer 2. Use the Immobilizer Control Module Part Number to
distinguish between Gen2 and Gen3. When looking up the transponder key part number for a Cabrio;
Please note that in ETKA under remarks, WFS-2 equals generation 2 and WFS-3 equals generation 3 (see
illustration).
– Immobilizers where the part number starts with 6H0 are Gen2 and should only use key part numbers
before and up to the VIN range in ETKA.
– Immobilizers where the part number starts with 6X0 are Gen3 and should only use key part numbers
from the VIN range and up as shown in ETKA. Currently, the correct part number for an immobilizer 2
generation 3 key is 7M3 837 219H. Always check ETKA for the latest part information.
