Abstract
A lock-and-alarm assembly includes an escutcheon formed with a through-hole. A lock core is formed with a keyway that can be accessed through the through-hole. A blind is detachably mounted in the through-hole for blocking access to the keyway through the through-hole. A switch is connected to the blind and is actuated upon removal of the blind, which, in turn, results in actuation of an alarm.
