Today’s locksmith fun fact:
The “dead” in deadbolt means the bolt isn’t spring-loaded. Unlike a beveled latchbolt, which retracts when pushed against the strike, a deadbolt must be positively moved by a key, thumbturn or other operating mechanism. Once thrown, pressure against the end of the bolt should not retract it.
A deadbolt isn’t called “dead” because it stops burglars dead... although stopping burglars is a pleasant side effect.
