About Z4 Keys
Verified key reference for the BMW Z4 — model years, key types, and the transponder/immobilizer each generation uses. Boundary years can overlap; we confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| Z4 (E85/E86) | 2002–2008 | Metal/slot key | EWS / CAS | HU58 / HU92 (confirm by VIN) |
| Z4 (E89) | 2009–2016 | Slot key / Comfort Access | CAS3+ | HU92 |
| Z4 (G29) | 2019–present | Comfort Access | BDC2 | HU100R |
Security System & Immobilizer
BMW security marched from EWS through CAS2/3/4 to FEM/BDC modules — each generation changes the programming approach.
On the Z4 specifically we see: EWS / CAS, CAS3+, BDC2. 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?
- 2002–2008: Metal/slot key — EWS / CAS (HU58 / HU92 (confirm by VIN))
- 2009–2016: Slot key / Comfort Access — CAS3+ (HU92)
- 2019–present: Comfort Access — BDC2 (HU100R)

BMW Z4 Key FAQ
I lost the only key to my Z4. 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 Z4?
On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
Do you still stock keys for older Z4s?
Yes — back to the 2002–2008 generation (metal/slot key), and a fresh code-cut key beats any copy of a worn original.
