ABSTRACT:
A device for removing a damaged locking cylinder, which eliminates the need for removing the escutcheon plates, which employs an internal locking bolt acting in concert with locking arms mounted on a locking plate, to selectively tighten or loosen the locking cylinder, as required, by use of an external adjusting mechanism which mates and co-acts with the locking bolt. Also provided is a cylinder protector which is affixed over the locking cylinder to deter vandalism of the cylinder by use of a tool.
