About PT Cruiser Keys
The table below is our verified key reference for the Chrysler PT Cruiser — 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 |
|---|---|---|---|---|
| PT Cruiser | 2001–2005 | Transponder | Texas Crypto 4D / 4D64 | Y160 (CY24) |
| PT Cruiser | 2006–2010 | Transponder | Philips ID46 / NXP PCF7941 | Y160 (CY24) |
Security System & Immobilizer
Chrysler’s Sentry Key immobilizer (SKIM) started with 4D64 chips, moved to Philips ID46, then to the WIN-module fobik key, and finally to Keyless Enter-N-Go proximity fobs on Hitag AES (4A) encryption.
On the PT Cruiser specifically, the immobilizer families we see are: Texas Crypto 4D / 4D64, Philips ID46 / NXP PCF7941. 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?

Chrysler PT Cruiser Key FAQ
I lost the only key to my PT Cruiser. 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 PT Cruiser call.
Will a hardware-store copy start my PT Cruiser?
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.
