I have a 2013 Honda Accord with a keyless entry system and can't figure out how to charge the keyless entry fob. I've looked in the manual and can't find anything about it. I asked the dealer and they don't know either.

Any ideas?

All the fobs I have had contain a small watch battery. They seem to last longer than I keep the car. I have had them last 7 or 8 years.

Older Honda keyfobs have a US quarter sized circle on the back with a groove in it. Stick a quarter (or your equivalently sized currency) in the groove and use it like a screwdriver. It will probably have an arrow on it, but if not anti-clockwise is the correct way to turn it. It will turn about ΒΌ of the way around and then you can pop it out (slap it against your palm if it's a bit stuck). The newer ones that are integrated with the key itself have a small screw on the back instead of a coin-sized slot (probably what you have if you've got a 2013 Accord).

Either way it probably contains a CR2025 (in US markets, at least) battery which you can then replace.
