KEYDIY has released a major enhancement for KD-X4 Key Programmer, introducing support for adding spare keys to BMW G Chassis vehicles equipped with BDC3 systems and BMW U Chassis vehicles using BCP immobilizers—an important advancement for professional locksmiths and automotive technicians.
Key Highlights of the Update:
1. New Platform Support: Add spare keys for BMW G Series (BDC3) and U Series (BCP) quickly and efficiently.
2. License Requirement: Uses the existing BMW G Chassis Programming Function license. If you previously activated
FEM/BDC2, you already have it—no extra purchase needed.
3. Low Per-Key Cost: Just 200 points (approx. 4 USD) per added key, deducted via the KEYDIY App.
4. Remote Compatibility: Only supports KEYDIY KD FGB Remotes (recommended models: FGB23 or FGB57).
5. Add-Key Only: This feature does NOT support all-keys-lost situations.
6. Original Key Data Needed: You must open the original key and read its data before generating a new one.
Which KEYDIY Remotes to Use:
FGB23 Remote: Suitable for BMW FEM, BDC, CAS4, CAS4+, and G Chassis key generation; also usable as a ZB key.
FGB57 Remote: Newest BMW-compatible remote; works with FEM, BDC, CAS4, CAS4+, and G Chassis; also functions as a ZB key.
