Replacing a CR2032 battery in your key fob is usually a straightforward process, and you can often do it yourself at home. Here’s a general guide, but remember to consult your car’s owner’s manual for specific instructions, as procedures may vary between car makes and models.

1. Gather your tools: You’ll typically need a small flat-head screwdriver or a similar tool to pry open the key fob casing. Sometimes, you might need a small Phillips head screwdriver. Have your new CR2032 battery ready.
