In this video tutorial, we will see how to disassemble and replace the battery of the key remote on an Audi A3 Sportback. First, take the remote in hand and lever off the rear cover with something sharp, like a flat screwdriver, to remove it; this will give you access to the battery located on the back of the remote.

At this point, remove the old battery and replace it with a new one of the correct type (in this case, a CR 2032 3V); insert it the right way round and reassemble the rear cover of the remote!
