GMC Acadia Key Replacement
GMC Acadias have been on Dallas–Fort Worth roads since the 2007 era, and across 5 key generations this model has used 5 different key systems — transponder; transponder philips crypto 2 / hitag 2 / id46 ⇆ pcf7936 / xt27a / t14 / jma tp12gm; smart-proximity (peps); transponder hitag 2 ext / ~id46, id46e / nxp pcf7937e, pcf7961e. 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 Acadia Keys
The table below is our verified key reference for the GMC Acadia — 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 |
|---|---|---|---|---|
| Acadia | 2007–2016 | Transponder | Philips Crypto 2 / Hitag2 / ID46 (PCF7936) | B111 (HU100) |
| GMC ACADIA | 2007-2016 | Transponder Philips Crypto 2 / Hitag 2 / ID46 ⇆ PCF7936 / XT27A / T14 / JMA TP12GM | ||
| Acadia | 2017–2020 | Smart-proximity (PEPS) | Hitag2 Ext / ID46E (emergency-blade chip) | emergency blade — FCC HYQ1EA |
| GMC ACADIA | 2017+ | Transponder Hitag 2 Ext / ~ID46, ID46E / NXP PCF7937E, PCF7961E | ||
| Acadia | 2021–2023 | Smart-proximity (PEPS), Global B | NXP HITAG-Pro / ID49 (NCF29A1) | emergency blade — FCC HYQ1ES |
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 Acadia specifically, the immobilizer families we see are: Philips Crypto 2 / Hitag2 / ID46 (PCF7936), Hitag2 Ext / ID46E (emergency-blade chip), 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 Acadia Key FAQ
I lost the only key to my Acadia. 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 Acadia call.
My Acadia is push-to-start. Can you really program that outside the dealer?
Yes. Late-model Acadias (2021–2023) 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 Acadia is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 2007–2016 generation (transponder), 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 Acadia 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.
