What is a deadbolt?

A deadbolt is a door lock that is typically operated with a key. Deadbolts are not spring loaded and can only be opened by rotating the interior cylinder with a key or the attached thumb knob. Deadbolts can have two cylinders (AKA Double Deadbolt) which require keys from both sides of the lock. Check with your county’s fire code to see if you can install this on your property. Other types of deadbolts include keyless entry deadbolts like keypads, fingerprint scanners, and mobile access locks. The picture provided shows an example of a double deadbolt (left) and a regular deadbolt (right).
