To replace the battery in an AUDI A3 remote control, you will need to obtain a Duracell model 2032 battery. First, extract the emergency key to gain access to the hole covered by it, then insert a screwdriver inside to release the shell of the key. Lift the shell to access the battery, then remove it. It is advisable to remove any dust accumulated inside the remote control; a great method is to use WD-40 spray and a cleaner, then dry with a microfiber cloth.

Insert the new battery into the designated space and close the remote control.
