Your 2016 Honda Accord key fob uses a CR1620 3V lithium coin cell. A fresh one typically lasts 3–5 years.

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