To change the battery on your Nissan key fab I actually need a quarter. There's a slot here on the end of the key. Put your quarter in there, turn it, and pop it open. There's a battery in here. You can try to get it out with your fingernails. If you can't, take a small flat bladed screw driver nad pop it out. They’ve got a little bit of spring to them.

It is a 2025 battery. Take your new battery. It'll go positive side down nad snap in. Put the two pieces back together, and the battery's replaced.
