About Liberty Keys
The table below is our verified key reference for the Jeep Liberty — 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 |
|---|---|---|---|---|
| Liberty | 2001-2004 | Texas Crypto 4D / 4D64 | TP21, TPX2 | |
| Liberty (KJ) | 2002–2004 | Transponder key | Texas Crypto 4D64 | Y160 / Y159 keyway |
| Liberty (KK) | 2005–2012 | Transponder key | Philips Crypto 2 ID46 (PCF7941) | Y160 / Y159 keyway |
| Liberty | 2005-2012 | Philips Crypto 2 / ID46 / PCF7936 / PCF7941AT | OHT692713AA |
Security System & Immobilizer
Jeep security follows the Chrysler ladder: Sentry Key 4D64 and ID46 transponders, fobik keys, and today’s Keyless Enter-N-Go proximity fobs with Hitag AES encryption.
On the Liberty specifically, the immobilizer families we see are: TP21, TPX2, Texas Crypto 4D64, Philips Crypto 2 ID46 (PCF7941), OHT692713AA. 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.

Jeep Liberty Key FAQ
I lost the only key to my Liberty. 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 Liberty call.
Will a hardware-store copy start my Liberty?
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.
My Liberty is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 2001-2004 generation (texas crypto 4d / 4d64), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
