Deadlocks

Deadlocks are the most popular and widely recommended type of van security lock. They operate completely independently of your van's factory central locking system — meaning even if a thief gains access to your cab or bypasses the electronic locking, the deadlock remains firmly engaged.

A deadlock uses a high-strength bolt that throws into a reinforced strike plate mounted on the door frame. It's operated manually with a separate key. Deadlocks provide excellent all-round protection and are suitable for virtually every commercial van door — side doors, rear barn doors, and tailgates.

Slamlocks

Slamlocks automatically lock the van door as soon as it's closed — no key needed to lock. This makes them ideal for couriers, multi-drop delivery drivers, and anyone who makes frequent stops throughout the day. You never have to remember to lock the van behind you.

Inside a slamlock, a spring-loaded mechanism engages when the door shuts. To open the door from the outside, you must use the key — every single time. This eliminates the risk of walking away from an unlocked van between deliveries.

Hook Locks

Hook locks are heavy-duty security locks featuring a hook-shaped bolt that engages with a reinforced keep (strike plate). The hook design creates a claw-like grip that provides exceptional resistance against 'peeling' attacks — where thieves attempt to pry the door away from the bodywork.

Peeling attacks are one of the most common methods used to break into vans, particularly targeting side doors and rear barn doors. Hook locks are specifically designed to counter this threat, making them an excellent choice for doors that are particularly vulnerable.

Side Door Locks

Side doors are the most frequently used entry point for van owners — and often the most targeted by thieves. We supply and fit specialist side door locks designed to protect sliding doors and side-hinged doors.

Options include deadlocks, slamlocks, and hook locks depending on your van model and access patterns. The right side door lock balances security with the convenience you need during the working day.

Rear Door Locks

Rear barn doors and tailgates are a major target for thieves — they offer access to the entire load area. We fit heavy-duty locks to both rear doors, providing maximum protection for your tools and equipment.

Deadlocks and hook locks are the most popular choices for rear doors, offering strong protection when the van is parked overnight or at the depot.
