What is a deadlock?

My insurer says I need a deadlock, what is that?

A deadlock requires either a digital codepad (mechanical or electronic) or key locking mechanism on both sides of the door. Deadlocks come in two types, Deadbolts & Deadlatches, in both cases when the door is closed the bolt/latch cannot be thrown without operating the locking mechanism.

Why does my insurer want me to have one?

If a burglar has successfully entered your home, perhaps through a window or skylight, being unable to open any of the external access doors prevents them from easily making off with your TV or other bulky valuables.

To satisfy insurance stipulations, all doors with external access must be fitted with a deadlock.

Common examples of a deadlock include this Carbine Double Cylinder, the very tough Lockwood 355, or this Austral SD7 for sliding doors. Other examples include mortice deadlocks, and combination deadlocks such as the Lockey 3210DCMG.
