Entrance Door Security
Entrance door security depends on the lock, the profile cylinder as well as the door frame and panel quality/ strength. It is necessary to use profile cylinders with security properties, such as key indentations (lateral drill holes) or self-locking mechanisms within the cylinder. Standard cylinders, that are still commonly used today, cannot prevent burglars from entering your property. Equipped with Electropicks and bump keys, the modern burglar will intrude your property in no time and might not even leave evidential traces of the burglary for your insurance.

The other element of entrance door security is the locking mechanism. A triple (or three-point) locking mechanism consists of latch bolts (also called lock bolts or locking pins) and two claw bolts (or hook bolts) combined with a strike plate within the door frame. This mechanism is usually sufficient to prevent even professional burglars to enter your property. Options to further increase the security are automatic locks, quintuple locks or even strong room locking systems. Alternatively, hinge-side security provided with interlocking teeth will prevent any intruder from entering on the hinged side of the door.
Restrictor/ Security Catch
If your entrance door does not allow you a clear view to the outside without opened, a restrictor is a good choice to ensure security. Similar to commonly used chains, you can prevent intrusion, even if a bolt cutter would be used. Especially in combination with spy holes, increased security is being provided.
