Photos show the OEM part for each number listed. Aftermarket replacements sold online are often slightly different in appearance — the FCC ID, not the shape, is what determines whether a fob will work with your car.
2003 Honda Odyssey key fob battery
Your 2003 Honda Odyssey key fob uses a CR2016 3V lithium coin cell. A fresh one typically lasts 3–5 years.
Find CR2016 batteries on AmazonHow to replace the battery
- 1 Find the seam or small slot on the edge of the remote.
- 2 Twist a coin or small flathead in the slot to split the case open.
- 3 Remove the old coin cell and note the + side.
- 4 Fit the new battery with the + side matching, then close the case.
- 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.
