Buick key systems at a glance

Our Buick reference currently covers 12 Buick models and 33 key options held in stock. Because Buick has changed key platforms several times, the chip and frequency are what decide whether a key works — not the badge on the key. Check both below before ordering.

Which frequency do Buick keys use?

The most common frequencies for Buick in our stock are 315 MHz, 433 MHz. A key with the wrong frequency will not lock, unlock or start the car, and frequency cannot be changed in software. Where a model was sold in more than one market, confirm the market version before ordering.

Key types we supply for Buick

Key types in this range: Smart Key, Remote Key. Smart keys need programming with a compatible tool, while flip keys, remote head keys and transponder blades are usually supplied as blanks for cutting and programming in your own workshop.

Programming Buick keys

Most Buick smart and flip keys in this range can be programmed with commonly available equipment such as Xhorse VVDI, KeyDIY KD-X or Autel IM508/IM608, depending on the model year. Some late-model vehicles still require online dealer access, and a small number cannot be added without an existing working key. Tell us which programmer you run and we will tell you which of these keys are realistic jobs for you.

Model years covered

This Buick range covers 1996-1999, 1997-1998, 2001-2005, 2005-2007, 2005-2009, 2006-2012, 2007-2017, 2017-2019 and other model years. Where a generation split exists (for example Golf 6 versus Golf 7, or Astra J versus Astra K), the model name changes the key — always confirm the generation before ordering.
