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.

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!

Doesn’t it have to be a Panasonic brand battery for it to work? I have the exact battery shown in picture mine takes a CR1620, I bought one from walmart but key pad still doesn’t work, help please!!! Honda wants to charge me $125 just to look at it to see what’s going on!!

If you have the right type of battery, brand should not matter at all. Make sure the metal battery contacts are all clean and making good contact with the battery. Try a second replacement battery if available, in case the first one was a dud. If none of that helps, you likely have some other issue that can’t be fixed with a battery.
