Garage doors: more locking points more security!

Garage security has recently been a hot topic in the Viro Security Blog. We have spoken about the importance of replacing the locks supplied as standard with the door with high security locks and how to best protect automated garage doors, both sliding and up-and-over ones, with electric locks and specific accessories. In addition to the fact that it can frequently represent a preferential route for thieves and intruders which leads straight into the house, the garage is also the place where the most bulky items such as cars, mopeds, bikes and other objects are kept which have both an economic and sentimental value.

How to increase the level of security of any cylinder

It doesn’t matter if a cylinder is low, medium or high level. You can greatly increase its resistance by protecting it with a security escutcheon.

How do you open a door if there is a key inside?

The quality of a lock is judged by how easy it is to prevent unwanted access. However, there are situations where the presence of a lock can represent a problem even for those who are authorised to gain access. This is especially the case where you need to quickly gain access to a house or a room to rescue a person closed inside who is unwell and unable to open the door. Indeed, with common double cylinder locks, if the key has been left inserted in the keyhole inside the house one is often unable to open the door from the outside, even having another correct key. To avoid this situation, which can result in the loss of valuable time in the event of an emergency, there are cylinders designed specifically to be opened (with the key!) from the outside even if a key has been left inside.
