Abstract:
A method for upgrading mechanical lock components within a hollow metal doorframe casing of a door by integrating said mechanical locking components with electronic access security components, said method comprising:(a) insertion of a magnetic field generating device between said previously assembled mechanical lock components, said insertion occurring while said magnetic field generating device is positioned exterior to said hollow metal door frame casing and, (b) electrically connecting said magnetic field generating device so it can override said mechanical lock components by activating a physically obstructing electronically controlled lock component, said physically obstructing electronically controlled lock component obstructing by vertical movement within said magnetic field generating device, said method occurring without modification to said hollow metal door frame casing, said magnetic field generating device being a solenoid, said electrically controlled lock component being a cam retaining locking bar with an attached hollow stem and interior small spring, said cam retaining locking bar with attached hollow stem and interior small spring inserted above a rocking lever after said assembled mechanical locking components are removed from said hollow metal door frame casing and placed in an upright position within a vise.
