A collar coacts with a chassis, sleeve and lever of a lockset to provide a retention and reinforcement system for lock assemblies. The collar has a flanged portion and a sleeve-engaging portion and is sandwiched between a lever and the cylinder. The sleeve-engaging portion includes at least one tab

A collar coacts with a chassis, sleeve and lever of a lockset to provide a retention and reinforcement system for lock assemblies. The collar has a flanged portion and a sleeve-engaging portion and is sandwiched between a lever and the cylinder. The sleeve-engaging portion includes at least one tab that engages the sleeve to retain the collar on the sleeve. Alternatively, the collar can be staked to the sleeve. A spring washer can be mounted between the collar and the chassis to take up variation in manufacturing tolerances. The result is a retention and reinforcement system that provides a protection against attack in the zone of attack around the handle-chassis interface.

A door locking system for a door having one or more bolts, comprising an opening opposite to each of the bolts in the door, each said opening having a receiver, an opening in each receiver adapted to receive a respective bolt, a strike moving horizontally within each said receiver between a first position in which a bolt cannot swing out of said receiver through said receiver opening and a second position in which a bolt can swing out of said receiver through said receiver opening, means to move the strike in a horizontal motion, electronic means comprising a controller, and means to activate the door locking system by moving each said strike between its first and second position, the system further comprising electronic means adapted to determine which of the receivers and strikes are associated with dead bolts and which of the receivers and strikes are associated with latch bolts. 5. A door locking system for a door having one or more bolts, comprising an opening opposite to each of the bolts in the door, each said opening having a receiver, an opening in each receiver adapted to receive a respective bolt, a strike moving horizontally within each said receiver between a first position in which a bolt cannot swing out of said receiver through said receiver opening and a second position in which a bolt can swing out of said receiver through said receiver opening, means to move the strike in a horizontal motion, electronic means comprising a controller, and means to activate the door locking system by moving each said strike between its first and second position, the system further comprising calibration control means adapted to enable a user to set the position of the strike within its receiver for the first position and the position of the strike within its receiver for the second position and store that information in the memory of said controller for remembering said first position and said second position. 6. A door locking system for a door having one or more bolts, comprising an opening opposite to each of the bolts in the door, each said opening having a receiver, an opening in each receiver adapted to receive a respective bolt, a strike moving horizontally within each said receiver between a first position in which a bolt cannot swing out of said receiver through said receiver opening and a second position in which a bolt can swing out of said receiver through said receiver opening, means to move the strike in a horizontal motion, electronic means comprising a controller, and means to activate the door locking system by moving each said strike between its first and second position, wherein the means to move each said strike within its receiver is an electromechanical actuator, which moves each said strike between its first and second positions in both directions, the system further comprising fault tolerance control means adapted to always return the strike to its preset first or second positions if forces other than that of the actuator shift the position of the strike within the receiver. 7. A door locking system for a door having one or more bolts, comprising an opening opposite to each of the bolts in the door, each said opening having a receiver, an opening in each receiver adapted to receive a respective bolt, a strike moving horizontally within each said receiver between a first position in which a bolt cannot swing out of said receiver through said receiver opening and a second position in which a bolt can swing out of said receiver through said receiver opening, means to move the strike in a horizontal motion, electronic means comprising a controller, and means to activate the door locking system by moving each said strike between its first and second position, the system further comprising sensor means to sense the presence of each dead bolt in a receiver, means to automatically move each said strike associated with a respective dead bolt from its second
