About Your 2026 Cadillac XTS
Cadillac is a USA brand owned by General Motors. Their key system uses GM PK3+ / Smart Key with UWB with Transponder, Smart Key with Digital Key. Cadillac combines GM's PK3+ immobilizer with premium smart key features. Newer models include Ultra-Wideband (UWB) technology for enhanced security.
The 2026 Cadillac XTS is a sedan. Most XTS keys of this generation use the Megamos AES / UWB transponder chip, remotes under FCC ID YG0G20TB1, the HU100 key blade — exactly the hardware we cut and program on-site. For this sedan we handle spare keys, all-keys-lost recoveries, and remote replacement curbside — at your home, office, or roadside in Jacksonville.
Your 2026 Cadillac XTS is a modern-era vehicle and uses the latest revision of Cadillac's key security platform. Programming requires advanced equipment but is fully aftermarket-supported on-site — no dealer trip needed in most cases.
Immobilizer (GM UWB): 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.
