The 2013 Nissan Sentra uses a CR2032 3-volt coin cell battery in the key fob. To remove the old battery, take something like a gift card or something similar that is thin but sturdy. Wedge it in between the two halves of the key fob and working way around prying it apart. You want to use something plastic that way You do not damage the outside of the fob. Once You get the two parts apart, use either Your fingernail or a flat blade MINI screwdriver to pop the old battery out. When You put the new battery in make sure the positive side is facing down, and that the battery is fully seated. Now align the two halves together and squeeze all around the outside edge to clip it back into place.
