About 5 Series Keys

The table below is our verified key reference for the BMW 5 Series — 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 5 Series specifically, the immobilizer families we see are: CAS2 / CAS3 / CAS3+, CAS4 / CAS4+, BDC2. 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?

  • 2004–2010: Slot key / Comfort Access — CAS2 / CAS3 / CAS3+ (HU92)
  • 2010–2017: Slot key / Comfort Access — CAS4 / CAS4+ (HU92 / HU100R (confirm by VIN))
  • 2017–present: Comfort Access / Display Key — BDC2 (HU100R)

BMW 5 Series Key FAQ

I lost the only key to my 5 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 — this is our most common 5 Series call.

Will a hardware-store copy start my 5 Series?

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.

My 5 Series is older — do you still stock keys for it?

Yes. We carry blanks and chips going back to the 2004–2010 generation (slot key / comfort access), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.

How fast can you reach my 5 Series in DFW?
