Abstract
Pin tumbler locks are provided that include features for detecting tampering. Tampering may be detected in a number of different ways. As an example, abnormal movement of one or more of the driver pins in a pin tumbler lock can be an indication of tampering. In addition, one or more sensors can be included at the end of a keyway that detect picking or bumping beyond the length of normal key insertion. A mechanical actuator can be used for detection.
Claims20
A pin tumbler lock, comprising:
- a body;
- a plug rotatingly mounted in the body and comprising a keyway for receiving a key;
- a key end defined in the keyway that corresponds to the end of a key inserted into the keyway when said key is positioned in a proper position to rotate the plug relative to the body;
- an actuator in the keyway positioned distal of the key end from an opening in the keyway, and configured and positioned to actuate in response to engagement with a foreign body inserted in the keyway when the foreign body extends beyond the key end;
- and
- a lockout mechanism, connected to the actuator, and configured to lock rotation of the plug in response to the actuator actuating.

- a key end defined in the keyway that corresponds to the end of a key inserted into the keyway when said key is positioned in a proper position to rotate the plug relative to the body;
- and
- an actuator in the keyway positioned distal of the key end from an opening in the keyway, and configured to engage one of an improper key and a picking device when the one of the improper key or picking device is inserted in the keyway and extends beyond the key end, without engaging an authorized key when the authorized key is inserted in the keyway.
