Abstract
An electronic device for impressioning a lock comprises a housing having a key decoder secured to the housing and a connector for connection to electronic circuitry. A key decoder portion extends from the housing for insertion into a keyway. A groove extends along a surface of the key decoder. An insulated conductor is positioned in the groove. An exposed portion serves as a reader of wafers positions in the keyway as the key decoder slides through the keyway. An electrical measuring device is secured to the housing and includes a slidable member including the reader, both of which are connected through a sensor interface included in the housing. When the reader engages and disengages with a wafer, the measuring device transmits electrical signals to the electronic circuitry which mathematically calculates a cut in a key blank for each wafer using stored programs for fitting a key to the lock.
