How to replace the battery in an Audi A6 key?
1 Answers
Use a screwdriver to open the back cover and unscrew the three screws. You will see the remote control split into two halves—one with the circuit board and the other with the casing. Take the half with the circuit board and pry it open. You will find a gray component in the upper right corner. Lift it to reveal the encryption chip. Behind the button rubber, there are screws. Open it to see the battery inside. Remove the old battery and replace it with a new one.
