Abstract

A tool is disclosed for opening tubular locks in which a tubular key is receivable. The tool includes a plurality of probes that are releasably retained and secured in a given position to align the shear points in the lock in an opening position. The probes can be ergonomically and individually manipulated and have a course and a fine adjustment, such that the shear point of each tumbler can be easily and efficiently determined. Once the shear point is determined, the probe may be fixed in the position to maintain each tumbler driver.
