2014 GMC Sierra-2500-HD key fob battery

Your 2014 GMC Sierra-2500-HD key fob uses a CR2032 3V lithium coin cell. A fresh one typically lasts 3–5 years.

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.
