What key does a GMC Acadia use?

It depends on generation. 2007–2016 (first gen) uses a remote key fob, FCC# OUC60221, 315 MHz, no push-to-start. 2017–2021 (second gen) uses a smart proximity key, FCC# HYQ1EA, 433 MHz. 2022–2023 uses HYQ1ES (same system, updated blank). 2024+ (third gen) uses YG0G21TB2.

My 2017 Acadia looks nothing like my neighbor's 2015 Acadia — why?

GMC significantly downsized the Acadia for 2017. The first-gen (2007–2016) was a large, three-row Lambda-platform SUV. The second-gen (2017+) is a compact crossover on the C1 platform — substantially smaller. They use different keys and have nothing in common mechanically.

Can I use a first-gen Acadia key on my second-gen?

No. OUC60221 and HYQ1EA are completely different key systems. They are not interchangeable in hardware or programming.

The Acadia has three distinct generations — and each generation uses a completely different key system. If the blank we're quoting doesn't match what you expect, year and generation matter more on the Acadia than almost any other GMC model.

First-gen Acadia (2007–2016) was a large Lambda-platform SUV — substantial vehicle, remote fob entry (OUC60221), no push-to-start. Second-gen (2017–2023) shrank significantly onto the C1 platform and gained push-to-start with HYQ1EA (2017–2021), then HYQ1ES for the mid-cycle update (2022–2023). Third-gen (2024+) is a full redesign and uses YG0G21TB2 — the same platform as the current Sierra and Yukon.

2017–2021: Second gen is significantly smaller than first gen — completely different vehicle. All trims use HYQ1EA.
2022–2023: HYQ1ES is not interchangeable with HYQ1EA blanks despite same push-to-start system.
2024–2025: GMT1 third-gen redesign — same key platform as 2022+ Sierra and 2021+ Yukon.

Common issues we see with GMC Acadia in Charlotte

First-gen (2007–2016): dead CR2032 battery is the #1 call. Mechanical key still opens the door — no lockout, just no remote entry or start.
Generation confusion is common. First-gen Acadia (2007–2016) is a large full-size SUV; second-gen (2017+) is a compact crossover. Year matters more on the Acadia than on most GMC models.
Second-gen all-keys-lost (2017–2023) requires professional programming. No DIY recovery once all paired fobs are gone.
Third-gen (2024+) key is not compatible with second-gen blanks — different platform, different FCC ID. Verify year before booking.

Why not the GMC dealer?

Randy Marion Buick GMC (Huntersville) handles all three Acadia generations but first-gen blanks (OUC60221) can require a 3–5 day parts order. We stock OUC60221 and HYQ1EA year-round.
