Back To Basics: Effective Forcible Entry


      c. If hinges exposed, pull hinge pins or drive tool between hinge and door facing

      d. Doors may be secured with a steel bar or fox lock (Steel bars may be conventional bars that are

          laid in slots or holders on each side of the door to prevent forced entry. They may also be a

          two-piece construction with a handle in the middle to allow the parts to slide to either side to

          secure the door similar to the securing mechanism for a residential garage door. The fox lock is a

          diagonal bar this is secured in a plate in the floor on one end and the middle of the door on the

          other. When a key is inserted or the door unlocked, the end of bar against the door is allowed to

          slide upward so that the door can be opened. For the two-piece bar and the fox lock, the

          locking mechanism on the face of the door is usually in the center of the door and appears as a

          rim lock. They may be forced if the lock cylinder can be pulled.)

      e. Doors with neither lock nor hinges exposed cannot be forced with standard tools (may have a

          bar holding the door from behind)

       f. Door that cannot be forced can be cut open with power saw

       g. Heavy steel door can be opened with a battering ram

       h. May have multiple locks

       i. Hydraulic spreaders may be used to separate double doors

  3. Lighted doors

      a. In many older buildings, rear doors made of wood or light metal, reinforced with bars or fitted

          with several locks

      b. Main lock should be forced first

      c. Additional bolts or locks can usually be forced with hand tools

      d. If door has glass pane without bars, best to remove glass and attempt to open lock from inside

      e. Some lighted glass doors may be equipped with wire glass which will require the use of a cutting

          tool such as an axe for glass removal

      f. Door outer edge made of wood or metal

  4. Tempered-glass doors

      a. For all practical purposes tempered glass cannot be broken

      b. Attack at the lock or find some other means of entry

      c. Locks usually Adams-Rite type located at middle or both of door

      d. Double tempered door locks located in middle

      e. Use lock puller (K Tool or A Tool) to remove lock

      f. If lock puller not available, drive chisel end of pry bar between lock and frame or between two

         sections to force open

      g. Alternative method is to drive bar into space above lock and then dive down to destroy locking


     h. For bottom locks, drive tool under door to displace keeper

     i. Hydraulic tools can be used to force apart double doors or raise lock at bottom

     j. Quickest way may be to force plate glass window near tempered glass door

     k. If tempered glass door must be broken, strike at lower corner of door with pick end of axe

  5. Heavy plate-glass doors

      a. Treat same as tempered-glass doors

      b. Usually has bar across center or lower center of door

      c. Better to remove or force lock or enter nearby plate glass window

  6. Sliding doors

      a. Sliding glass with cylinder locks or some bolting arrangement at the edge, top, or bottom

      b. Locks or bolts should be forced with available tools

      c. If door particularly tough to force, drive pry tool between door and framing

      d. Sliding doors may be lifted at the bottom to dislodge the lock

      e. Two doors locked to each other can also be opened by driving pry tool between doors

      f. Break glass for entry only for immediate rescue or when glass already stained or damaged by

         heat or smoke

      g. When bar or rod holds sliding section, glass will have to be broken

  7. Roll-up doors

      a. Doors opening upward might be locked in several ways
