A Deadlock is a mechanical device fitted to a vehicle door. It operates by throwing a bolt into a receiver fitted to the opposing body section when operated by an external key.

Working independently from the manufacturer’s locking system, the Deadlock fires a bolt that hooks over either a bracket or into the door post, bracing the doors together. It offers the operator the flexibility to use the extra security when required, and when fitted higher in the door, it also protects against the door from being bent down.

As Deadlocks are under the control of the driver, they are generally only appropriate for owner drivers or applications where the driver can be relied upon to operate the lock.

We fit locks supplied by Locks 4 Vans who are a specialist in leading locking solutions for all vans and are the UK’s largest automotive deadlock and slamlock supplier.  All L4V cylinders, housings and plugs are plated in highly durable satin nickel to maintain a consistent and long lasting appearance. External trims are available as either UV stabilised black Nylon, or satin nickel-plated brass to maintain the aesthetic appearance of the vehicle. Both versions are suitable for fitment to vehicle bodywork without causing damage to paintwork. Note Black external trims supplied as standard.

  • What is the difference between a deadlock and a slamlock?

    A Deadlock requires the key to lock and unlock, and is completely separate from the existing locking mechanism. A Slamlock however, automatically engages when the door is closed and integrates with the existing locking mechanism.

  • Can all locks work with the same key?

    Each lock comes with 2 identical keys that operate all locks within that kit.

  • How long does a lock installation take?

    Depending on the type of lock fitted, it can take up to 1 1/2 hours per lock.
