GMC Yukon Key Replacement
The Yukon is the family full-size SUV of choice in Weddington, Waxhaw, and Ballantyne. We see them as daily drivers and three-row haulers regularly. Yukon and Yukon XL use identical keys — if you searched for Yukon XL key replacement, this page applies to your vehicle too.
The Yukon changed key systems at the 2021 full T1XX redesign. K2XX (2015–2020) split between a standard remote fob on SLE/SLT and a 6-button smart proximity key on Denali — these are different FCC IDs and not interchangeable within the same year. T1XX (2021+) unified the lineup on HUFGM2718/YG0G21TB2 across all trims. Denali owners with a $90k+ MSRP vehicle should budget accordingly — a lost T1XX Yukon key is a $350+ event at the dealer.
Key types by year — GMC Yukon
| Years | Key type | FCC ID | Starting price |
|---|---|---|---|
| 2015–2020 (SLE / SLT trim) | Remote key fob (push-button keyless entry, no push-to-start) | M3N32337100 | $175 |
| 2015–2020 (Denali trim) | Smart proximity key (push-to-start, 6-button illuminated) | HYQ1AA | $220 |
| 2021–2024 | Smart proximity key (push-to-start, all trims including Denali) | HUFGM2718 | $220 |
- 2015–2020 (SLE / SLT trim): K2XX base trims. Same year range uses HYQ1AA on Denali — confirm trim before ordering.
- 2015–2020 (Denali trim): K2XX Denali smart key — not compatible with M3N32337100 base-trim remote blanks.
- 2021–2024: T1XX full redesign — all trims unified on same key. Also listed as YG0G21TB2 by some suppliers (same device, alternate FCC designation).

Common issues we see with GMC Yukon in Charlotte
- T1XX (2021+): mechanical key is stored inside the fob. Hidden door-handle slot allows entry on dead battery. Many owners discover this for the first time roadside.
- Yukon Denali AKL (all-keys-lost) on K2XX requires a locksmith or dealer to re-seed the BCM — the standard remote-fob self-programming trick does not apply to HYQ1AA.
- T1XX Denali and base SLE use the same FCC ID. The physical blank is the same. Any dealer premium for Denali key replacement on T1XX is a trim surcharge, not a different key.
Why not the GMC dealer?
Randy Marion Buick GMC (Huntersville) prices T1XX smart key replacement at $350–$450 with programming. Multi-day parts wait is typical for Denali-spec keys.
