About i3 Keys
Verified key reference for the BMW i3 — 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 |
|---|---|---|---|---|
| i3 | 2013–2018 | Comfort Access | BDC | 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 i3 specifically we see: BDC. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

BMW i3 Key FAQ
I lost the only key to my i3. 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 i3?
On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
