Audi Q5   Controls   Doors and windows  Central locking system
If the central locking system should fail to work, you can still lock and unlock the driver's door by turning the emergency key or spare key in the lock.
Unlocking
Turn the key to position -A- Fig. 1 to unlock the vehicle.
Locking
Move the selector lever to position P (automatic gearbox).
Turn the key once to position -B- WARNING! to lock the vehicle.
If you turn the key to position -B- a second time within 2 seconds, this will lock the vehicle without activating the deadlock mechanism.
In order to switch off the anti-theft alarm*, you must switch on the ignition within 15 seconds after opening the driver's door. Otherwise the alarm will be triggered.
WARNING!
Do not leave anyone (especially children) in the car if it is locked from the outside and the deadlock mechanism is activated: the doors and windows cannot then be opened from the inside. Locked doors could delay assistance in an emergency, potentially putting lives at risk.
