To replace the key battery of a Volkswagen Atlas, start by obtaining a replacement battery of the correct type, a CR2032. Locate the slot for opening the key, located on the back. Use a flat screwdriver or a thin object to gently open the slot and separate the two halves of the key. Once opened, locate the old battery inside the battery compartment and carefully remove it using a small screwdriver or a similar object.

Be sure to note the orientation of the battery. Insert the new battery in place of the old one, paying attention to the correct orientation.

Close the key shell, ensuring that the two pieces snap together properly. Perform a test to verify that the key functions correctly, ensuring that the buttons respond as expected and that the key can still open and close the doors and start the vehicle.

Once the key's proper functioning is confirmed, keep the old battery for safe and appropriate disposal.
