Remote / key fob programming

On the Buick Century and Regal you can program remotes yourself by holding the door's Unlock switch while cycling the key. Reprogram every remote, including working ones.

Full steps: Buick Century and Regal Remote Programming

Key programming

This key fob can't be programmed with a do-it-yourself procedure. The vehicle needs a diagnostic tool connected to its OBD port to pair a new fob, so a replacement has to be set up by an automotive locksmith or a dealer.

Order the correct replacement fob below — match the FCC ID on your current fob first — then have a local automotive locksmith or the dealer program it to your vehicle.

Buick Regal key fob battery

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

Buy Energizer CR2032 Lithium Coin Batteries (4-pack) on Amazon

How to replace the battery

  1. 1 Find the seam or small slot on the edge of the remote.
  2. 2 Twist a coin or small flathead in the slot to split the case open.
  3. 3 Remove the old coin cell and note the + side.
  4. 4 Fit the new battery with the + side matching, then close the case.
  5. 5 Press a button to confirm the LED lights, then test at the car.

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 remote still doesn't work after a new battery, it may need re-syncing or programming.
