A method for improving the security of doors and doorways that are mounted in a structure frame wherein a doorway includes a threshold, a header, and a doorjamb, said doorjamb defining a finished surface and that also defining a rough surface that is oppositely disposed from said finished surface, said doorjamb also having a bolt hole between the finished surface and the rough surface, said method comprising the steps of:

• locating a first reinforcement plate between the rough surface of the doorjamb and the structure frame, said first reinforcement plate having a bolt hole and also having a top end and a bottom end;
• vertically positioning the first reinforcement plate such that the top end of the first reinforcement plate is vertically between the top end of the doorjamb and the doorjamb bolt hole, and such that the bottom end of the first reinforcement plate is vertically between the bottom end of the doorjamb and the bolt hole of the doorjamb, and such that the bolt hole of the first reinforcement plate is in registry with the bolt hole of the doorjamb;
• locating a second reinforcement plate between the rough surface of the doorjamb and the structure frame, said second reinforcement plate having a bolt hole, a bottom end, and a top end;
• and
• vertically positioning the second reinforcement plate such that the bottom end of the second reinforcement plate is vertically between the bottom end of the doorjamb and the doorjamb bolt hole, and such that the top end of the reinforcement plate is vertically between the top end of the doorjamb and the bolt hole of the doorjamb, and such that the bolt hole of the second reinforcement plate is in registry with the bolt hole of the first reinforcement plate and in registry with the bolt hole of the doorjamb.
