Look at your key fob. See that tiny notch or slot on the side? That’s the secret entrance. Pop the mechanical key out first if your fob has one. Just slide it out like you’re drawing a tiny sword.

Now, take your screwdriver (or dime) and gently wedge it into that notch. Twist just a little. You’ll hear a satisfying pop as the two plastic halves separate. Don’t panic—it’s meant to do that.
Inside, you’ll see the battery sitting in its little plastic cradle. It might be held in by a metal clip. Gently pry it out with your tool or fingertip. Say goodbye to the old, dead disc. It served its purpose.
The Moment of Truth
Slide your new CR2032 battery into the spot. Make sure the plus side (+) is facing up. Most fobs want the plus side up, but check the old battery’s position before you yank it out. Snap a mental photo first.
Press it down firmly until it clicks into place. Then take the two plastic halves of the fob. Line them up carefully and squeeze until you hear another snap. Not too hard—you’re not crushing a can.
Now, put your mechanical key back in if you removed it. Give your fob a little shake. If it doesn’t rattle, you won. Take a victory lap around your living room.
