ABSTRACT:
A pick for tubular cylindrical locks which includes a central substantially cylindrical member which has a plurality of grooves thereon, each groove to accommodate an elongated pin. The pins are capable of axial movement with respect to the cylindrical member against the action of a frictional brake in the form of rubber O-ring assembly. The very tip of the pins connect with a head which is adapted to be placed about the rotatable cylinder portion of a tubular lock. The head includes a series of axial slots and upon being moved axially into the cylindrical member, the head slightly deflects and frictionally secures to the cylinder portion of the lock. The head is moved axially by a fastener which connects between the rearwardmost end of the first member and the head.
