Abstract: A cylinder lock removal tool comprises a generally cup-shaped casing having an annular side wall and an end wall with the annular side wall defining a generally cylindrical bore. A cylindrical collet sized to be received within the casing bore has a set of radially spaced resilient fingers extending from a collet base. A sleeve has an interior cylindrical surface sized to be slid over and in sliding engagement with the collet fingers and base, and an exterior cylindrical surface sized to be received within the casing annular wall. The tool also includes a threaded bolt for drawing the collet and sleeve into the casing bore.
