Standard locking function means that all doors and hatches are locked or unlocked simultaneously. The exception is the fuel tank filler cover which is unlocked with unlocking but locked after 10 minutes or when the vehicle reaches a speed of 16 km/h (10 mph). With locking or unlocking a confirmation is normally given via the direction indicators that the central locking has successfully performed the operation. If locking or unlocking did not succeed no confirmation is given. This confirmation also applies to the alarm functions if an alarm is installed in the vehicle. For more information on the alarm system, see ALARM, IMMOBILIZER, AND VOLVO ON-CALL - DESIGN AND FUNCTION .

Locking/unlocking of the vehicle can be performed with: 

When using the key: 

When locking with the key in the door lock, a hatch or a door can still be open. Doors and locks will be locked and remain locked after being closed. However, the alarm will not be activated if the vehicle has this setting (key set). This setting is made in the vehicle's configuration file which is stored in the central electronic module (CEM).

The switches on the inside of the front side doors are deactivated if the vehicle is locked with a key. To be able to lock the vehicle with the switches all doors must be closed.

When locking with the remote control: 

For remote control locking to be possible there must no key belonging to the vehicle in the ignition switch.

When locking, one or more doors or hatches can still be open. The alarm functions will be activated and confirmation given when the last door or hatch is closed. If the function for deadlocking is installed then this will be activated 25 seconds after the last side door is closed. The fuel tank filler cover is locked automatically after 10 minutes.

When locking with central locking switches: 

Locking with central locking switches can only take place if all doors are closed. If a door is open when a switch is pressed then the doors will be locked and then immediately unlocked again. The central locking switches are disconnected when the vehicle is locked from the outside, with a key or the remote control.

Normally the vehicle is unlocked by activating the remote control unlocking button. Depending on settings, this can also deactivate the alarm if installed. If the setting for alarm deactivation on key unlocking is not made then the alarm will be triggered if the vehicle is unlocked with a key. The alarm can then be reset by inserting the ignition key into the ignition switch.
