About Your 2026 Buick Terraza
Buick is a USA brand owned by General Motors. Their key system uses GM Passlock / PK3 / PK3+ with Transponder, Smart Key. Buick uses GM's mainstream immobilizer technology. Most modern Buick models support aftermarket key programming through OBDII.
The 2026 Buick Terraza is a sedan. Most Terraza keys of this generation use the Hitag2 / Megamos AES transponder chip, remotes under FCC ID HYQ4EA, the HU100 key blade — exactly the hardware we cut and program on-site. Key blanks for the Terraza are stocked on the truck, so a typical spare-key visit anywhere in Duval County wraps up the same day, without a tow.
Your 2026 Buick Terraza is a modern-era vehicle and uses the latest revision of Buick'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.
