ABSTRACT:
A conversion kit allows a user to convert a deadbolt lock mechanism into a pick proof deadbolt lock mechanism by providing all the necessary parts allowing a user to easily and effectively prevent the turnpiece latch of the deadbolt lock mechanism from rotating. Once installed, a locking shaft pin of the kit can be placed into a first orifice drilled through the turnpiece latch and a second orifice, coaxially aligned with the first orifice, drilled through the backplate to immobilize the turnpiece latch in its locked position. It would also allow a deadbolt manufacturer to use the same, in which case collars could be an O-ring style.
