Howdy! I'm a big battery nerd so I put together a quick guide to the Accord (and other Honda vehicles) key fobs, and what battery powers each one. It's a fun project for me to make sure everyone can quickly figure out how to change their key batteries. I hope this is helpful for visitors in the forum.

If your key is this one:
Battery needed: CR1616
If you have this older fob:

If you have this really old fob:

If you need videos of changing the above fob batteries, check out my full Accord page: Honda Accord Key Battery Replacement Guides
