GMC Yukon Key Replacement
GMC Yukons have been on Dallas–Fort Worth roads since the 1998 era, and across 7 key generations this model has used 7 different key systems — passlock anti theft system; mechanical / non-transponder; transponder / remote-head; transponder philips crypto 2 / hitag 2 / id46 ⇆ pcf7936 / xt27a / t14 / jma tp12gm. 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 Yukon Keys
The table below is our verified key reference for the GMC Yukon — 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 |
|---|---|---|---|---|
| GMC YUKON | 1998-2006 | PassLock Anti Theft System | ||
| Yukon | 1999–2006 | Mechanical / non-transponder | PassLock (no chip) | B102 / B106 |
| Yukon | 2007–2014 | Transponder / remote-head | Philips Crypto 2 / Hitag2 / ID46 (PCF7936) | B111 (HU100) |
| GMC YUKON | 2007-2014 | Transponder Philips Crypto 2 / Hitag 2 / ID46 ⇆ PCF7936 / XT27A / T14 / JMA TP12GM | ||
| Yukon | 2015–2020 | Smart-proximity (PEPS), 6-button | Hitag2 Extended / ID46E | emergency blade — FCC HYQ1AA |
| GMC YUKON | 2015-2020 | Transponder Hitag 2 Ext / ~ID46, ID46E / NXP PCF7952E, PCF7937E | ||

Security System & Immobilizer
GMC trucks follow GM’s security ladder — VATS, PassLock, PK3/PK3+ transponders, ID46 Circle+ keys, and modern proximity fobs — each with its own programming path our equipment covers.
On the Yukon specifically, the immobilizer families we see are: PassLock (no chip), Philips Crypto 2 / Hitag2 / ID46 (PCF7936), Hitag2 Extended / ID46E, NXP HITAG-Pro / ID49 (NCF29A1). 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.

GMC Yukon Key FAQ
I lost the only key to my Yukon. 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 Yukon call.
My Yukon is push-to-start. Can you really program that outside the dealer?
Yes. Late-model Yukons (2021–2024) use a proximity smart key on the NXP HITAG-Pro / ID49 (NCF29A1) system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
My Yukon is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 1998-2006 generation (passlock anti theft system), 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 Yukon in DFW?
