Vehicle Coverage (BDC3)
Heads-up: coverage applies to some BDC3 models only, with emphasis on keys produced in Hungary. Actual support depends on the BDC3 hardware version present in the vehicle. Always confirm the module is BDC3 and the chip is 2951/2953B before purchase or use.
| Model (example) | Chassis | Approx. Years | Notes |
|---|---|---|---|
| 3 Series (some variants) | G20 / G21 | 2020-2024 | Depends on BDC3 hardware |
| 4 Series (some variants) | G22 / G23 / G26 | 2020-2024 | Priority on Hungary-built BDC3 |
| 5 Series LCI (some variants) | G30 / G31 | 2020-2023 | Verify BDC3 on module label/PN |
| X3 / X4 (some variants) | G01 / G02 | 2020-2024 | Hardware-dependent |
The table above is guidance only. Always verify BDC3 by module label and hardware in the target vehicle.
