Etymology
Origin of deadbolt
Explanation
A deadbolt is a type of lock that you need a key to open. It's very common to have a deadbolt on an apartment door or the front door of a house. When you turn a key in the lock of a deadbolt, the bolt slides in or out of an opening in the door jamb. Deadbolts are considered to be secure locks that are difficult to open without a key, especially when compared to a spring-loaded lock, the kind you see in the center of a doorknob. While spring latches can be pushed back manually, deadbolts can't — which is why they're called deadbolts. They're dead, or unmovable.
