BMW 5 Series Key Replacement
BMW 5 Seriess have been on Dallas–Fort Worth roads since the 2004 era, and across 3 key generations this model has used 2 different key systems — slot key / comfort access; comfort access / display key. 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 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.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| 5 Series (E60/E61) | 2004–2010 | Slot key / Comfort Access | CAS2 / CAS3 / CAS3+ | HU92 |
| 5 Series (F10/F11/F18) | 2010–2017 | Slot key / Comfort Access | CAS4 / CAS4+ | HU92 / HU100R (confirm by VIN) |
| 5 Series (G30/G31/G38) | 2017–present | Comfort Access / Display Key | BDC2 | HU100R |
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.
