What to expect
Buick key jobs vary by year and trim — older models often use a basic transponder chip while newer ones run proximity or push-to-start keyless systems.
When you submit a request, we route it only to a partner equipped for your specific Buick make — not to whichever locksmith answers first.

Buick key replacement at a glance
Buick is GM's premium-mainstream brand now focused entirely on crossovers — Enclave, Encore GX, Envision, Envista. Buick has settled into a tight crossover-only lineup positioned between Chevrolet and Cadillac per Cox Automotive sales data. The Buick fleet uses GM immobilizer family: PassKey III/PK3+ (2004-2013), HITAG-2 (2014-2017), HITAG-AES proximity (2018+).
Typical pricing runs $175-$425 all-in. A 2017 Enclave HITAG-2 spare runs $165-$235; a 2024 Enclave Avenir HITAG-AES all-keys-lost runs $315-$425.
Buick is a routine GM-family job — no NASTF VSP, no per-VIN PIN, no display-key complications.
Why Buick keys are different
Buick shares GM architecture documented across Chevrolet/GMC/Cadillac. The Enclave shares Chevrolet Traverse platform; Envision built in China and exported but shares GM global-A architecture.
Docs via GM TechInfo. No Buick-specific quirks beyond broader GM lineup. The 2024+ Envista and refreshed Encore GX use refined HITAG-AES.
