Audi A1 Controls Doors and windows Central locking system
If the central locking system should fail to work at any time, the passenger's door will have to be locked separately.
A mechanical locking device (only visible when the door is open) is provided on the front passenger's door.
Pull the cap out of the opening.
Insert the key in the slot inside and turn it as far as the stop to the right (if the door is on the right side) or to the left (if the door is on the left side).
Once the door has been closed it can no longer be opened from the outside. Pull the interior door handle once to unlock and open the door.
