Central locking system: Locking/unlocking

Saab 9-3 is standard equipped with central locking system for all markets.

In each door there is a lock unit, which in the driver's door comprises a lock cylinder, microswitch, electric motor and lock. In the other doors, there is only the electric motor and lock. The central locking function is controlled by the TWICE control module. The central locking system can be locked/unlocked using the key, remote control or the button on the center console. Convertibles do not have the button on the center console and the central locking system is instead operated from the lock buttons in the doors. The central locking system cannot be operated with the remote control when the key is sitting in the ignition.

The central locking system can be operated with the key in the driver's door.

The lock has a rotating lock cylinder, which means that it will rotate freely if the wrong key is used or if a forced entry is attempted.

The central locking system cannot be unlocked from the inside with the lock button in the driver's door, but only with the button on the center console. The lock buttons in the doors only lock or unlock each respective door.

The rear doors are provided with child safety catches that are activated with a small handle by the door lock. When the child safety catch is activated, the door can only be opened from the outside, provided the lock button is not pushed down.

The central locking system motors are supplied with power via fuse 25 to pin 47 on the TWICE control module, and when activated, TWICE will check the power flowing through the motors.
