Jeep Grand Cherokee Key Replacement
Jeep Grand Cherokees have been on Dallas–Fort Worth roads since the 1998 era, and across 10 key generations this model has used 7 different key systems — texas crypto 4d / 4d64; transponder key; philips crypto 2 / id46 / pcf7936 / pcf7941at; fobik (integrated). Whichever yours is, DFW Keys 4 Cars cuts and programs it at your location, 24/7: spare keys, lost-everything replacements, fob programming, and lockouts. Call (214) 717-6398.
About Grand Cherokee Keys
The table below is our verified key reference for the Jeep Grand Cherokee — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, and trim levels (keyed vs. push-to-start) can differ within the same year, so we always confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| Grand Cherokee | 1998-2004 | Texas Crypto 4D / 4D64 | TP21, TPX2 | |

| Grand Cherokee | 2004-2007 | Philips Crypto 2 / ID46 / PCF7936 / PCF7941AT | KOBDT04A, OHT692427AA | |
| Grand Cherokee (WK) | 2005–2007 | Transponder key | Philips Crypto 2 ID46 (PCF7936/7941) | Y160 / Y159 keyway |
| Grand Cherokee (WK) | 2008–2010 | FOBIK (integrated) | Philips ID46 (PCF7941) | Y160 emergency insert |
| Grand Cherokee | 2008-2013 | Philips Crypto 2 / ID46 / Hitag 2 / PCF7961 | IYZ-C01C, M3N5W783X, 56046733AA | |

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 Grand Cherokee specifically, the immobilizer families we see are: TP21, TPX2, Texas Crypto 4D64, KOBDT04A, OHT692427AA, Philips Crypto 2 ID46 (PCF7936/7941), Philips ID46 (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.

Jeep Grand Cherokee Key FAQ
I lost the only key to my Grand Cherokee. 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 Grand Cherokee call.
My Grand Cherokee is push-to-start. Can you really program that outside the dealer?
Yes. Late-model Grand Cherokees (2021–2023) use a proximity smart key on the Hitag AES / ID47 (NCF29A) system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
My Grand Cherokee is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 1998-2004 generation (texas crypto 4d / 4d64), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
How fast can you reach my Grand Cherokee in DFW?
We dispatch the nearest mobile unit across the whole metroplex, 24/7. Call (214) 717-6398 with your location and we’ll give you an honest ETA.
