Solution

1. Preparation

Gather tools: small flathead screwdriver, multimeter, and OBD-II scanner.
Ensure you are working in a clean, dry environment.

2. Open the Key Fob

Using a small flathead screwdriver, carefully pry apart the key fob casing.
Take care not to damage any internal components during the opening process.

3. Inspect and Test Battery

Remove the new battery and test it with a multimeter to ensure it has the correct voltage (typically 3V for most key fobs).
If the battery does not show the correct voltage, replace it with a new, verified battery.

4. Reassemble the Key Fob

Ensure all internal components are seated properly before reassembling.
Snap the key fob casing back together securely.

5. Reprogram Key Fob (if necessary)

Insert the key into the ignition and turn it to the "On" position without starting the engine.
Press the lock button on the key fob for a few seconds; this may reset the fob.
If the fob does not respond, consult the owner’s manual for specific reprogramming instructions for the XC60.
