About S40 Keys
Verified key reference for the Volvo S40 — 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 |
|---|---|---|---|---|
| S40 (1st gen) | 1996–2004 | Transponder key | Philips ID44 (Crypto) / earlier ID73 | HU56 |
| S40 (2nd gen, P1) | 2004–2012 | Remote-head / fobik key | Megamos Crypto ID48 | HU101 |
Security System & Immobilizer
Volvo used Megamos ID48 and Philips ID46 chips through the 2000s before SPA-platform DST-AES smart keys.
On the S40 specifically we see: Philips ID44 (Crypto) / earlier ID73, Megamos Crypto ID48. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Volvo S40 Key FAQ
I lost the only key to my S40. 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 S40?
On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
