To replace a car key battery, you can try these steps:

1. Open the key fob
Most key fobs open like a clamshell, with a seam that separates the front and back halves. You can use a small, flat-bladed screwdriver or butter knife to gently pry the fob open in a few places around the edges.

2. Find the battery
The battery is usually located underneath a circuit board. You may need to lift or remove the circuit board to access the battery.

3. Remove and replace the battery
Note the orientation of the old battery so you can put the new one in correctly.

4. Snap the fob back together
Test the new battery by locking and unlocking the vehicle and starting it.
