Deadlocks – Deadlocks are mechanical devices that are fitted to a vehicles door once it’s already come off of the production line. When the key is turned in its lock, a bolt is thrown into a receiver that’s fitted to the opposing body section of the vehicle. Once locked, they are near impossible to break, hence the Thatcham approval.
Slamlocks – Slamlocks are simpler than deadlocks but just as effective. Unlike deadlocks where you have to actually lock the device, Slamlocks make sure the door automatically locks as soon as the door is shut.
High Security Replacement Door Cylinders - Most commonly installed on Ford vans, which are known for being lock picked or the door cylinder being twisted by mole grips in order to gain entry.
