When the key is in the half-turned position, it blocks the lock mechanism and prevents an external tool from easily intervening. This makes it considerably more difficult for burglars, who must first push the key outwards before being able to manipulate the lock.
An effective tip, but not infallible
Although this simple gesture increases the security of your door, some Internet users have pointed out limitations to this method:
“What if the thief breaks a window to get the key?” asks one user. This scenario is plausible, but breaking a window makes noise, which most burglars prefer to avoid.
“Burglars almost never pick locks,” others say. Indeed, many prefer more direct methods, such as forcing a poorly secured window or door. However, this trick remains useful for slowing down an intrusion and deterring opportunistic thieves.
A key in the door: an advantage in case of emergency
Beyond protection against theft, keeping a key inserted in the lock can also save lives in times of danger.
