About Your 2026 GMC Yukon
GMC is a USA brand owned by General Motors. Their key system uses GM Passlock / PK3 / PK3+ with Transponder, Smart Key. GMC uses the same GM platform as Chevrolet. The Sierra and Yukon share key systems with their Chevrolet counterparts.
The 2026 GMC Yukon is a sedan. Most Yukon keys of this generation use the Megamos 48 / Hitag2 transponder chip, remotes under FCC ID M3N-32337200 / HYQ1EA, the B111 / HU100 key blade — exactly the hardware we cut and program on-site. GMC programming is fully aftermarket-supported, so one mobile visit covers key cutting, chip programming, and remote pairing in a single stop.
Your 2026 GMC Yukon is a modern-era vehicle and uses the latest revision of GMC's key security platform. Programming requires advanced equipment but is fully aftermarket-supported on-site — no dealer trip needed in most cases.
Immobilizer (GM PK3+): GM's PK3+ has been refined since 2007 and is one of the easier mainstream platforms to program. Aftermarket coverage spans every Chevy, GMC, Buick, and Cadillac of the era.
