The process is straightforward and requires minimal tools. Here’s a step-by-step guide:

Locate the release button: This is usually a small button or slot on the back or side of the key fob.
Separate the key fob halves: Use a small flathead screwdriver or a key to gently pry open the key fob at the seam. Be careful not to damage the plastic.
Identify the battery: It’s usually a small, round, flat battery, often a CR2032.
Remove the old battery: Gently pry out the old battery with your screwdriver or fingernail. Avoid puncturing or damaging the battery.
Install the new battery: Make sure the positive (+) side of the new battery is facing upwards, just like the old one. Press it firmly into place.
Reassemble the key fob: Snap the two halves of the key fob back together. You should hear a click when it’s secure.
