Replacing the battery is a simple and quick operation. Take the key and press the button to release the metal blade.

Look for a small gap on the back of the key: insert a flathead screwdriver or a thin object and gently pry open the shell. Inside you will find the battery, usually a CR2032. Remove it carefully, avoiding touching the contacts too much, and insert the new one with the positive side (+) facing upwards.

Close everything, pressing firmly until you hear a click. Now your key is ready, try using it to make sure it works.

If you don't feel comfortable doing it yourself, contact an expert.
