2019 Buick Regal Key Fob Programming

Updated 2026 Programming, battery & replacement fob

You can program a 2019 Buick Regal key fob yourself in a few minutes using a working key or remote, no dealer visit needed. Follow the steps below, then check the battery and the correct replacement fob (with FCC ID and part number) if you need a new one.

If your GM vehicle (Cadillac, Chevrolet, Buick) has push-button start, you can program smart keys yourself. Use Method A if you have two working smart keys; use Method B if you have one or none. Up to 8 smart keys — read the steps through first.

Before you start

  • All smart keys — working and new — with you
  • Engine off

Method A — with two working smart keys

  1. 1Remove the emergency key blade from one of the working smart keys.
  2. 2Place both working smart keys in the cupholder.
  3. 3Insert the emergency key blade into the driver's-door lock cylinder and turn it counterclockwise to unlock five times within 10 seconds. (On some vehicles you'll first pop off the lock-cylinder cap on the door handle.) The Driver Information Center shows READY FOR REMOTE #2.
  4. 4Place the new smart key in the transmitter pocket — center-console storage for Cadillac, front cupholder for Chevrolet and Buick.
  5. 5Press ENGINE START/STOP. When the key is recognized, the display is ready for the next key.
  6. 6Take the key out of the pocket and press Lock or Unlock on it.
  7. 7To add another key, repeat the last three steps. When done, press and hold ENGINE START/STOP about 12 seconds to exit.

Method B — with one or no working smart key

Takes about 30 minutes and isn't available in Canada. With no working key, have the new key's emergency blade cut by a locksmith first.

  1. 1Remove the key blade from your existing or new smart key.
  2. 2Insert it into the driver's-door lock cylinder and turn counterclockwise to unlock five times within 10 seconds. The display shows READY FOR REMOTE.
  3. 3Wait about 10 minutes until the display reads PRESS ENGINE START BUTTON TO LEARN, then press ENGINE START/STOP. The display shows REMOTE LEARN PENDING, PLEASE WAIT.
  4. 4Repeat that door-cylinder, wait, and Start/Stop sequence two more times. After the third, all previously known keys stop working and the display shows READY FOR REMOTE #1.
  5. 5Place the new smart key in the transmitter pocket — center console for Cadillac, front cupholder for Chevrolet and Buick.
  6. 6Press ENGINE START/STOP. When recognized, the display is ready for the next key.
  7. 7Take the key out and press Lock or Unlock on it.
  8. 8To add another key, repeat the last three steps. When done, press and hold ENGINE START/STOP about 12 seconds to exit.

2019 Buick Regal key fob battery

Your 2019 Buick Regal key fob uses a CR2032 3V lithium coin cell. A fresh one typically lasts 3–5 years.

How to replace the battery

  1. 1 Look for a small notch or screw on the side of the fob where the key blade meets the buttons.
  2. 2 Pry the housing apart with a coin or small flathead (or remove the screw).
  3. 3 Pop out the old coin cell, noting its orientation.
  4. 4 Insert the new battery the same way up, then snap the case shut.
  5. 5 Test the buttons — if they work, you're done.

Battery tips

  • Use a fresh, name-brand 3V lithium cell — bargain cells drain quickly.
  • Try not to touch both faces of the new battery; skin oils shorten its life.
  • If the buttons still don't respond after a new battery, the remote may need re-syncing or programming.
