CAS4 Cloning, Programming and Preparation
The BMW CAS4 5WK50920BBR should not be treated as a component that can simply be connected to every vehicle without further preparation. The required procedure depends on the condition of the original module and the vehicle configuration.
- cloning or transferring data from the original CAS may be possible if its data can still be read correctly,
- depending on the vehicle, programming and module synchronisation may be required,
- before preparation, compatibility with the vehicle and the other components of the starting system should be verified,
- the set includes the CAS module and the keys shown in the photos.
If you still have the original CAS module, we recommend sending us a photo showing its label clearly. This allows us to determine the most suitable preparation method before installation.
