Por qué es necesario evitar dejar las llaves en la cerradura de la puerta?

¿Por qué ya no dejar la llave dentro de la cerradura?

Many people are convinced that leaving the key in the door, especially at night, will deter potential intruders. This is just a dangerous and unfounded popular belief! You may not realize it, but leaving the key in the lock inside the house is a great opportunity for thieves. And for good reason, they can easily use a small hook to make a simple maneuver and enter your home discreetly. Most burglars can quickly bypass the mechanism of locks: there is no need for a special tool to release the internal protection of the lock. When burglars target your home, they can use any sharp object such as a wire or a hanger hook to try to turn the key left inside and open the lock effortlessly. They can thus enter your home discreetly. Therefore, leaving the key in the lock significantly increases the risk of burglary. It is better to keep your keys in a safe place (out of the reach of thieves). Obviously, a reinforced door remains the most secure option to prevent any possible break-in. It resists most attacks and its locking system is stronger. However, do not skimp on the means and especially avoid cheap offers: a quality reinforced door is rather expensive, but it guarantees you more security.

¿Se puede abrir una puerta incluso si hay una llave al otro lado?

Yes, as long as your door is equipped with a friction cylinder lock or a lock with an emergency function. These two types are designed to be unlocked with a key, even when there is another key on the other side of the door.

Even keys can attract dust and lint particles that come from pockets or bags. Therefore, all this dirt can then be transferred to the lock. Over time, the accumulation causes a blockage: that’s why the key can get stuck inside the lock hole. The solution? You need to lubricate this area to unlock your key. You can easily find suitable lubricants for this problem at any hardware store. The procedure is simple: use the nozzle to spray directly into the top of the lock hole. Then gently move the key up and down to release it. Be careful not to swing it from side to side, as you could break your key.
