The original battery in my 2012 Honda Civic Key is a Panasonic CR1616, not a CR1620. I bought an Energizer CR1620, and it was too thick.

Thanks, Harry!

This isn't the same key remote that I have for my 2015 Civic Si (Sedan). Mine is more square shaped and the key is removable from the inside of the device. It also has no apparent opening-point anywhere around it. The only spot I would consider a possible entry point would be where the key is removed.

Robert;

Yes, once the key is removed it is just a matter prying it apart from between the two ears that stick up from the center. A fairly thick flat-bladed screw driver will do it (i used the handle end of a tweezer that was handy). This takes a CR2032 battery, (3) volt, very commonly found. There are two little tabs holding it in, plus (+) side up. Just snap it all back together. Voila.
