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.

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.

my 2012 remote doesn't look like this, nor does it have the same battery. it takes CR1616, and once you open the casiing, it has a second casing that needs to be opened.

I had to replace CAR battery and now, while the key works, the 5-button fob from HONDA doesn’t. Does anyone know the code of key presses for it?

Perfect job, good steps and photos.  However some 2013 Accords  do not have a Phillips screw,  instead you move the tiny spring loaded button on the side to release the metal key,  pull it out,  then look for a fortified slot inside and turn a butter knife to open-split the case, go carefully.  NOTE- some of the 2032 batteries have a safety sticker on one face, “do not swallow”  you must remove it for the battery to work at all..  Happy Honda!
