Whichever yours is, DFW Keys 4 Cars cuts and programs it at your location, 24/7: spare keys, lost-everything replacements, fob programming, and lockouts. Call (214) 717-6398.


About X1 Keys

The table below is our verified key reference for the BMW X1 — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, so we always confirm the exact part by VIN before dispatching.

Security System & Immobilizer

BMW security marched from EWS through CAS2/CAS3/CAS4 to the FEM/BDC modules on current cars. Each module generation changes the key-programming approach — including bench work on some — which is exactly what our BMW tooling is for.

On the X1 specifically, the immobilizer families we see are: CAS3+, FEM-BDC. A key that is cut correctly but not programmed to this system will turn the locks and never start the engine — programming is the half of the job that matters.

Which key does your year have?

  • 2010–2015: Slot key / Comfort Access — CAS3+ (HU92)
  • 2016–2022: Comfort Access — FEM-BDC (HU100R)

BMW X1 Key FAQ

I lost the only key to my X1. What now?

We come to the vehicle, verify ownership, cut a new key from the VIN, and program it on-site. No tow, no dealer wait — this is our most common X1 call.

Will a hardware-store copy start my X1?

It will open the doors and nothing else on transponder-era cars — the chip inside the key must be programmed to the immobilizer, which is the part we do curbside.

How fast can you reach my X1 in DFW?

We dispatch the nearest mobile unit across the whole metroplex, 24/7. Call (214) 717-6398 with your location and we’ll give you an honest ETA.
