Why does this gesture work?
Because in the half-turned position, the key blocks the lock's internal system. It's then impossible for an external tool to push it back without forcing it. And forcing means more time and more noise ...exactly what burglars are trying to avoid.
A clever trick, but not infallible
Be careful, however: this quarter turn does not transform your door into a safe. Some Internet users rightly point out that burglars often use much more direct methods: a fragile window, a poorly locked door, or even a door left ajar.
That said, making their task a little more complicated can be enough to discourage them. Just like in cooking: if the recipe has too many steps, we often end up giving up. It's the same here: the more obstacles there are, the fewer temptations there are.
Keeping the key in the door: an asset in case of emergency
Beyond security, having a key in the lock can also save lives. In the event of a fire or gas leak, being able to immediately open your door without panicking and searching for keys is a valuable advantage . Some people who have experienced this type of situation say that this reflex has saved them precious seconds.
But here again, the quarter turn remains essential: the key must be well positioned to avoid transforming this reflex into an additional risk.
Our practical advice to strengthen your security
- Turn the key slightly in the lock when you are at home.
- Install a multi-point lock : it's an investment that really strengthens your door.
- Avoid leaving a key visible behind glass or near an entrance.
- Add simple protections like a safety bar or chain.
- Consider modern deterrent devices : connected camera, alarm or simple light motion detector.
