  • Publication number: 20090013740
    Abstract: My invention is to provide a new and useful apparatus for preventing the rotation of a key to open a deadbolt lock or the lock to be picked. By manufacturing the faceplate on the inside of the door out of solid metal. This would allow a slot to be machined in the face plate where I could put in a lever with a pivot screw, allowing the lever to be pulled out keeping the knob from turning and the dead bolt lock from unlocking. This may also be used on a side garage door or any entrance door to a home.
