Steps vary by remote, but replacing the battery is usually quick. Use a small flathead screwdriver or plastic pry tool to gently open the fob case, note the old battery's size and orientation (commonly CR2032 or CR2025), and install the correct replacement in the same position. Snap the case back together and test all buttons.
Before you start
Have your replacement battery ready, along with a small flathead screwdriver or plastic pry tool and a clean, flat surface so you don't lose any small parts. Pay close attention to the old battery's orientation as you remove it, installing it backward is one of the most common reasons a fob won't work afterward.
It varies slightly by key style
Smart keys, remote head keys, flip keys, and standard remotes each open a little differently, usually through a small notch or seam somewhere along the edge of the case. If yours doesn't come apart easily, don't force it, look for the seam first.
