Deadlocks and slam locks add a strong, visible layer of protection to commercial vehicle doors. We recommend the right setup around how often you open the vehicle, where it is parked and what you carry.

Built for working vehicles
Factory locking systems are designed for convenience, but tradespeople, couriers and fleet operators often need a tougher secondary barrier. Professionally fitted security locks operate independently from the original central locking, helping protect rear and side-loading doors even if the vehicle key or factory system is compromised.
We assess door construction, daily access patterns and driver routines before recommending deadlocks, slam locks or a combination of both. Installation is planned to look discreet, work reliably and avoid unnecessary disruption to the vehicle.
An additional mechanical barrier separate from the vehicle’s standard locking system.
Lock positions and hardware are selected around the make, model and door construction.
The right system balances strong protection with the way drivers actually use the vehicle.
Deadlocks
Deadlocks are manually operated with a separate key. They suit vehicles that need strong overnight security or drivers who want full control over when the secondary lock is engaged.
Slam locks
Slam locks are ideal for delivery work and frequent stops. The load door secures as soon as it closes, reducing the chance of it being left unlocked during a busy route.
