Forcible Entry (7th Edition)
Chapter 6-Forcing Locks
Test Review

  • The process of retracting the latch from the strike with a thin, flexible object is called loiding.
  • Loiding is not effective on deadlocking latches due to the deadlatch preventing the latch from clearing the strike.
  • Once the cylinder of has been removed from a deadlocking latch, the internal mechanism can be operated to release the latch from the strike.
  • When the locking mechanism on a rim lock has been exposed and cannot be retracted with a key tool, the inside portion of the lock should be punched out, allowing the latch to clear.
  • Multibolt locks are found in the center of a door.
  • Rim cylinders are located higher on a door than a mortise cylinder.
  • Mortise cylinders are set at the center-edge of a door near the knob.
  • There are many other methods that cause less damage than through-the-lock entry.
  • Classroom training and practical applications are the most effective training for forcible entry.
  • K-tools are designed to pull rim and mortise lock cylinders.
  • High-quality, high-security tubular deadbolt locks are the most resistant to forcible entry.
  • Cylinder guards on mortise locked can be forced by shearing the cylinder guard bolts with a cutting tool.
  • If the cylinder of a rim lock becomes damaged, the locking mechanism will still be intact.
  • Cutting torches are useful on all types of padlocks.
  • A Halligan tool can be used to force a padlock by twisting, prying, or striking.
  • Training, method used, and the type and quality of lock determines the amount of damage that results from through-the-lock entry.
  • Before retracting the latch on a bored key-in-knob lock using the internal latching mechanism, the cylinder must be pried from the door.
  • The best method for forcing a mortise lock with a flush-mounted cylinder is by pulling the cylinder.
  • Mortise locks have threaded cylinders.
  • A night latch is a feature of a rim lock that can prevent a key tool from retracting the latching mechanism.
  • The steps in forcing an interlocking deadbolt with a security plate on the outside of the door is to first, shear the bolts from the plate to expose the lock cylinder, second, pull the cylinder with a K- or A-tool.
  • The most common type of exit device is the rim type.
  • A padlock attached to a door hasp is best forced by twisting.
