Buick Key Fob and Car Key Programming

How Buick car keys and key fobs are programmed, by model year, what you can sometimes do yourself, and when a mobile automotive locksmith is the faster, safer choice. Dealerkeys programs Buick keys on site across East Tennessee.

Buick key programming by model year

Buick uses a different key system for older and newer vehicles. Find your vehicle below.

Buick 1998–2005

May be self-programmed (older system) Models: LeSabre, Regal, Century, Rendezvous

Method: On-Board Key Fob Programming

  1. Close all doors.
  2. Press and hold driver's door UNLOCK switch.
  3. Turn ignition switch ON/OFF twice (ON, OFF, ON, OFF).
  4. Release door UNLOCK switch (door locks will cycle).
  5. Press and hold LOCK and UNLOCK on remote for 15 seconds until locks cycle.

Note: Standard GM onboard programming procedure for older remotes.

Buick 2006 and newer

Locksmith required Models: Enclave, LaCrosse, Regal, Encore

Method: OBD2 / 10-Minute Learn Procedure

Many transponder keys use a 10-minute onboard key learn (turn ignition ON with new key for 10 mins until security light goes off, repeat 3 times), but push-to-start smart keys require OBD2 programming tool.

Note: Check specific model year; newer models require internet access or GM SPS2 programming.

This guide is general information. Procedures vary by model, trim and equipment, and a wrong attempt can leave a vehicle unable to accept new keys. Call or text with the year, make and model, and we will tell you what yours needs.

Can you program a Buick key fob yourself?

Some older Buick models (LeSabre, Regal, Century, Rendezvous, 1998–2005) list an on-board method above. Even where one exists, it usually needs a working key or remote to start it, it differs by model and trim, and it often programs the remote only, not a chip key. Newer Buick vehicles, and any key whose chip the car must recognize, need a diagnostic programming tool.

What to have ready when you call

The year, make and model of the vehicle, the VIN if you can read it through the windshield, and where the vehicle is parked. Tell us how many keys you have left, if any, and what kind of key you want. Plan to be with the vehicle, with your ID and registration, title or other proof of ownership.

What if I lost all my Buick keys?

We come to you, open the vehicle if it is locked, make a new key for your Buick and program it on site, so there is no tow to a dealer. You need to be with the vehicle, with ID and proof of ownership.

How much does a Buick key replacement cost?

It depends on the model, the year and the type of key. Call or text with the year, make and model, and we quote the price before any work begins.
