A slamlock is a device that automatically locks the vehicle door immediately it is shut, without requiring any operation by the driver.

• The Slamlock is primarily designed for couriers, multi-drop delivery drivers and any operations where a driver may be regularly in and out of a loading area throughout the day. The L4V Slamlock safeguards against the driver forgetting to lock the doors. Once the door is shut it locks automatically and can only be opened using the L4V Slamlock key, reducing the chances of theft.
