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.

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.

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.
