While getting through locked doors is generally considered the vocation of thieves it can also be a handy skill in a lot of other scenarios, the most common being when a key for a door around the house or office has become locked. The first and perhaps best known is to pick the lock. Most locks around the house these days use a cylinder locking mechanism, which works by using tiny metal pins that fit inside the cylinder to prevent it from turning. In the case of an emergency then (or if you‘ve just given up with the fiddly lock picking), you may want to break the door down. Instead you’re much better off kicking the door with the heel of your shoe and aiming for the weakest point on the door. Depending on what you’re locked out of you may also want to consider breaking in through a window, or climbing in through a window if its been left open.
