Which BMW keys do we make?
Older BMWs (roughly the mid-1990s to mid-2000s) used the EWS immobilizer. Later models moved to the CAS module, then FEM/BDC on newer platforms, with Comfort Access proximity keys on many.

A key the car stops recognizing, a damaged fob, Comfort Access not unlocking the doors, and all keys lost.
Newer BMW models
Many EWS, CAS, and FEM/BDC keys can be programmed on-site with BMW-capable equipment. For newer models, we have dealer authorization and dealer-level software, so the newest keys are usually programmed on site too. Have the VIN ready; we confirm the exact key for your car on the phone.

BMW key questions.
Can you make a BMW key without the original?
For many models, yes. Depending on the module (EWS, CAS, or FEM/BDC), we program a new key at the car. We confirm the model and year on the phone first.
What is the difference between CAS and FEM on a BMW?
They are generations of the module that stores which keys the car accepts. The generation decides how a new key is programmed.
Does a MINI key work the same way as a BMW key?
Yes. MINI uses the same BMW module families, so the process is similar.
Do you come to where my BMW is parked?
Yes. We are fully mobile. Wherever your BMW is in Baltimore City or Anne Arundel, Baltimore, Carroll, Harford, or Howard county, a technician comes to you.
Is a BMW key from a locksmith as good as one from the dealer?
Yes. We program BMW keys to the same immobilizer system, using dealer-level software, and test the key on your car before we leave. We don't publish prices; we quote your exact year and model on the phone.
