  1. BMW Key Fob Replacement

    A replacement BMW key must match the vehicle’s security module and frequency before it can be programmed. We identify the system your BMW uses, confirm the right key and program it so the remote and start functions work.

  2. CAS, FEM & BDC Modules

    Depending on the generation, the key is managed by the CAS, FEM or BDC module. Lost keys, module replacement or certain faults can require coding of that module. We assess the module and explain the work involved before proceeding.

  3. FRM Footwell Module

    On many BMW and MINI models, the footwell module (FRM) controls exterior lighting, power windows and related functions. A failed or corrupted FRM can cause lights or windows to stop working. We diagnose it and explain whether it can be reprogrammed or needs to be replaced and coded.

  4. Dealer-Level Diagnostics

    Key and module problems on BMW vehicles often show up together with other warnings. We read the vehicle’s modules to find the actual fault instead of replacing parts by guesswork.

Proof of ownership and identification are required for key and security services. Availability depends on the vehicle and its equipment.

Common Questions

Can you program a BMW key if all keys are lost?

In many cases, yes. The process depends on the model and its security module (CAS, FEM or BDC). Contact us with your vehicle details and proof of ownership.

Do you program MINI keys too?

Yes. MINI uses BMW security systems, and we program and replace MINI keys and key fobs as well.

Can I use a used BMW key from another car?

Some BMW keys can be prepared for reuse and others cannot. Send us the key details and we will check compatibility before you book.
