Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Lock Unit With Quick Lock Functionality
The lock unit is installed in the relevant door's rear end. The lock unit has a quick lock function which is used to reduce the reaction time of the system. The lock unit has an integrated switch which is closed when the outer door handles are pulled out to their limit positions. The switch is mechanically connected to the exterior door handle by a control arm. This allows the keyless vehicle module (KVM) to activate the quick lock motors and open the door on which the handles was pulled out. The quick lock motor is activated after a remote key has been validated by the keyless vehicle module (KVM). The quick lock is mechanically connected to the catch in the ordinary lock mechanism. On activation, the quick lock turns the catch so that it releases the striker plate in the body. This means that when the handle is pulled out on a door, the door opens as soon as the keyless vehicle module (KVM) has validated the remote key. This reduces the reaction time of the system considerably.
The key unit is powered by the keyless vehicle module (KVM).
