Abstract: A door lock secures a door when closed within a doorframe. The lock includes a bolt guide, a bolt, a bolt actuator, and a bolt receiver. The bolt includes a first portion that is adjacent to a proximal end and a second portion that is adjacent a distal end of the bolt. The actuator moves the bolt along the bolt guide between a locked position and an unlocked position. The second portion extends beyond the guide when in the locked position and is received by the receiver. The bolt deforms within the receiver and thereby predominantly absorbs energy from an intrusion load. A maximum deformation of the bolt prior to failure of the lock from the intrusion load is at least 4%, 25%, or 120% of a thickness of the bolt. A maximum deformation of the bolt prior to failure of the lock may be at least 40%, 55%, or 72% of a maximum overall deflection of the lock. The receiver may include a deformation guide that guides deformation of the bolt.
