Abstract
A lockset is provided with a sensor assembly for detecting tampering with the cylinder. A lock cylinder with a cylinder body and a cylinder plug disposed in the cylinder body is provided. The cylinder plug is configured to deform and/or separate from the cylinder body when a sufficient force is applied. A sensor assembly is provided that detects when the cylinder plug deforms and/or separates from the cylinder body. In some embodiments, the sensor assembly could detect when the cylinder plug deforms and/or separates from the cylinder body with a strain gauge, a continuity circuit, a micro-switch, an optical sensor, an accelerometer and/or a contact microphone.
