About 6 Series Keys

Verified key reference for the BMW 6 Series — model years, key types, and the transponder/immobilizer each generation uses. Boundary years can overlap; we confirm the exact part by VIN before dispatching.

Security System & Immobilizer

BMW security marched from EWS through CAS2/3/4 to FEM/BDC modules — each generation changes the programming approach.

On the 6 Series specifically we see: CAS2 / CAS3 / CAS3+, CAS4 / CAS4+. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Which key does your year have?

  • 2004–2010: Slot key / Comfort Access — CAS2 / CAS3 / CAS3+ (HU92)
  • 2011–2018: Slot key / Comfort Access — CAS4 / CAS4+ (HU100R)

BMW 6 Series Key FAQ

I lost the only key to my 6 Series. 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.

Will a hardware-store copy start my 6 Series?

On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
