When choosing an additional locking system for your van it’s worth while making sure you choose the right choice. Many people get confused over which type does what and how exactly they lock. It is very simple to understand to be honest. Deadlocks are a simple catch with a euro cylinder mounted in the door, these locks are only locked when you manually throw the key within the lock and to unlock you simply turn the key round in the euro cylinder. These locks are very similar to a deadbolt which is fitted on some front doors in your home. Busy tradesman only deadlock there vehicle at night when they need the additional security to protect there tools in most cases.
Slam locks are a very good idea and are mostly used by parcel delivery companies where they unload each parcel and slam the door each time and each and every time the door locks behind them meaning they will never forget to lock the door. The only risk to these products is leaving the keys in the vehicle and slamming the door behind you. This is why I would always suggest carrying a spare key on you. The slam locks can be bypassed from inside the vehicle if you get locked in meaning your safety is never at risk.
