When the system for keyless entry is installed, the Keyless vehicle module (KVM) checks the identity of the remote key when unlocking and locking. The Keyless vehicle module (KVM) then transmits a command to the opening motor in the door where the handle was pulled out.

The opening motor affects the catch in the lock unit mechanically, when the opening motor is activated the catch releases from the striker plate in the body and the door opens.

If the lock is locked when the opening motor is activated, the lock unlocks automatically.

The Keyless vehicle module (KVM) checks the identity of the remote key using the antenna in the external handle on the rear side doors and in the tailgate.

The remote key is checked when one of the handles on the side doors or the handle on the tailgate is activated. The Keyless vehicle module (KVM) activates one of the external antennas to check the identity of the remote key.

The vehicle is locked using the lock buttons on the door handles. During locking, the antenna is also activated to check that there is an authorized remote key in the vicinity of the vehicle. If the remote key is approved, the keyless vehicle module (KVM) transmits a signal to the central electronic module (CEM) to lock the vehicle.
