What technique is used for forcible entry with mortise locks?

The technique known as "through the lock" is specifically designed for forcible entry with mortise locks. This method allows firefighters to bypass the locking mechanism without causing extensive damage to the door itself, which is particularly beneficial in situations where preserving property is important. The technique typically involves drilling a small hole or using a specially designed tool to manipulate the internal components of the mortise lock, effectively unlocking it from the inside.

Employing this technique can significantly reduce the time it takes to gain entry while also minimizing the risk of creating additional hazards, such as debris from a damaged door or frame. Understanding this method is crucial for firefighters, especially when responding to emergency situations where quick and efficient entry is essential.

While other methods like using an axe, breaking the door knob, or utilizing hydraulic tools can also be effective in various situations, they may not be as precise or may result in greater property damage. The "through the lock" technique is tailored to address the specific challenges presented by mortise locks, making it the preferred and most efficient choice in this scenario.
