GMC Key & Ignition Pricing in Dallas
Ranges current as of July 2026. Final price depends on model year, key type, and whether a working key still exists — confirmed on the phone before dispatch.
| Service | Typical range | What drives it |
|---|---|---|
| PK3 / PK3+ transponder key — cut and programmed | $120–$200 | Turn-key models; includes cutting to code from the VIN and the theft-deterrent programming pass. |
| Folding flip key with integrated remote | $180–$320 | 2014–2018 Sierra and same-era SUVs; rehousing existing electronics lands at the low end. |
| Smart proximity fob | $250–$350 | Push-button models — newer Sierra, Yukon, Acadia; includes cutting the concealed emergency blade. |
| All keys lost (add-on) | +$75–$250 | Added when no working key exists and GM's theft-deterrent system must complete a full relearn. |
| Theft-deterrent / immobilizer relearn | $120–$280 | The timed GM relearn after battery, BCM or ECM work — done to procedure so the security light clears. |
| GMC lockout entry | $85–$200 day / $125–$275 after-hours | Non-destructive entry — keys locked in a running work truck are a common Sierra call. |
GMC Models We Service in Dallas
GMC Sierra 1500
2007–2013PK3+ transponder and remote-head keys verified by the BCM — identical architecture to the same-year Silverado, and the same 'Service Theft Deterrent System' failure pattern.
GMC Sierra 1500
2014–2018Folding flip key standard; a broken hinge is a rehousing job, not a new key, when the truck still starts.
GMC Sierra 1500
2019–presentProximity fob with push-button start on most trims; the newest VINs sit on GM's tightened-access architecture, confirmed by VIN before dispatch.
GMC Yukon / Yukon XL
2015–2020Proximity fob standard — fob-not-detected complaints after a battery change usually resolve at the fob, not the BCM.
GMC Terrain
2010–2017Flip-key era Terrain; the BCM hosts the theft-deterrent logic and a cranks-no-start with the security light lit is the classic relearn call.
GMC Acadia
2017–presentPush-button start on most trims — key work is fob programming plus the concealed emergency blade cut to code.

About GMC Key & Module Systems
GMC vehicles use the identical GM theft deterrent system as Chevrolet. The BCM manages key recognition and engine start authorization. We service all GMC models on-site using GDS. GMC's lineup shares GM's security platforms with Chevrolet, which is good news for coverage: the same PASS-Key, Passlock, transponder, and proximity generations appear across Sierra, Yukon, Canyon, Terrain, and Acadia, and the same BCM-centered relearn procedures apply. The trucks bring their own patterns - work-truck Sierras often live their whole lives on basic transponder keys that wear alongside heavily used ignitions, while Denali trims carry full proximity systems from the same year the equivalent Cadillac did. A security light with a crank-no-start is most often the theft-deterrent system doing its job against a worn key or a failing passlock sensor rather than a dead module, and the timed relearn procedure resolves it without parts. On Global B-era trucks the gateway changes what tooling is required, so the year and VIN drive the plan. For fleet operators running multiple Sierras, duplicating spares while keys still exist is dramatically cheaper than serial all-keys-lost calls.
Where the honest limit is
Because GMC shares Chevrolet's theft-deterrent platform outright, nearly the whole lineup is on-site work, all-keys-lost included. The honest ceiling is the newest model years on GM's latest electrical architecture, where programming access has been tightened, and trucks whose BCM or engine controller was replaced with mismatched security data — those can need module-side work with its own price. Send us the VIN and model year and we confirm exactly what your GMC needs before we dispatch a truck.
