Mechanical pushbutton lock provides fully mechanical access control, while allowing free egress at all times by interior thumbturn. Deadbolt models must be manually relocked. Deadlocking spring latch models automatically relock each time the door closes. This fully mechanical lock eliminates the material and labor expense of battery replacements, has a single access-code and is programmed via the keypad without removing the lock from the door.
