| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| ForTwo (451) | 2008–2015 | Remote-head/flip key (3+1 btn) | PCF7941 (ID46 family) | FCC KR55WK45144, 315 MHz, VA2 blade, PN A4518203797 |

Security System & Immobilizer
Smart 451 keys are Mercedes-family (KR55WK45144, PCF7941) and programming is a total write — every key must be present or it stops working.
On the ForTwo specifically we see: PCF7941 (ID46 family). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

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