How to Replace the Battery
To replace the battery, you’ll need a CR2032 3V lithium coin cell and a small tool or coin to pry the shell apart. The following steps describe a typical replacement process for most Accord remotes.
- If your fob has a removable mechanical key blade, release and remove it first according to the fob’s design.
- Use a small coin or flat tool to gently pry open the back cover at the seam. Do not force it; apply even pressure until the cover pops loose.
- Remove the old battery, noting which side was facing up (the orientation helps ensure correct installation).
- Insert the new CR2032 with the positive (+) side facing up, ensuring it sits flat and contacts the terminals evenly.
- Snap the back cover back into place and reinsert the mechanical key blade if you removed it. Test the fob by pressing a button to confirm it works.
After replacement, dispose of the old battery according to local regulations and test the fob to confirm reliable operation. If the fob still doesn’t work, check the battery contacts and consider a dealer or locksmith inspection for potential internal issues.
Summary
