Door, key and locks are the three magic words when it comes to home security. Everything you need to know to guard against the risk of burglary.

The door

A resistant door It is the privileged access of burglars. Whatever the material, it is important to check its resistance to burglary. This resistance depends on the quality of the frame (the door frame), the opening (or vent, that is to say the door itself), and the hinges, themselves fixed on small metal parts called hinges. The three-dimensional hinges offer better resistance to forcing, lifting and sinking. But an ultra-resistant door is of little use if its locking system is of poor quality. Reinforced door You can armor your door by fixing a steel shielding sheet on the inside. But pay attention to the weight of the whole so as not to damage the hinges. Or install a sealed metal frame in the masonry. This will delay the crowbar break-in. You can also change your door for an armored door block. The leaf then has a metal structure on its four sides and an armor sheet in its center. Today there are very aesthetic, even designer door blocks. In addition, door units can benefit from A3P certification.

The key

It is also an actor in our home security. There are unprotected keys (infinitely reproducible by anyone to whom you have entrusted your keys) and protected keys. For the latter, its reproduction requires showing your property card, given at the time of purchase. It is reproduced by the manufacturer. Its warranty is generally valid for 20 years. Beyond that, its reproduction falls into the public domain. There are a few rare key brands for which the manufacturers have obtained a three-dimensional trademark deposit. The protection is then unlimited in time.

The lock

It is the main security equipment in our home. Its degree of safety depends on the complexity and robustness of the system used. There are two types: the mortice lock and the overlay lock. The first is embedded in the thickness of the door. Invisible, it keeps the aesthetics of the door. The second is better suited to thin doors. There is also a distinction between single-point locks and multi-point locks (or security lock). A multipoint lock has several bolts (moving parts of the lock). It thus distributes the closing points over the entire door, preventing burglaries at the crowbar, in particular. Three-point locks are commonly found (with a single control point, that is, they open with a single key), but some can go up to ten. Insurers often require their customers to equip their front door with a multi-point lock with at least three locking points. The cylinder, which receives the key, must also be safe. The more pins it has (from 5 to 36), the higher its level of security.

Standards and labels

There are three: - The NF standard, issued by AFNOR, which guarantees a constant level of quality in a manufacturer's products. - The CE label, which guarantees that the manufacturer has placed on the market a product which complies with all the provisions of the European directives which concern it. - The A3P label, issued by the National Center for Prevention and Protection (CNPP), an official body recognized by insurance professionals. It is classified into three categories (1, 2 or 3 stars) depending on the level of resistance. Please note: to guarantee the resistance to burglary of an A2P labeled product, the lock, cylinder and accessories (in particular the strikes) must be of the same brand and of the same A2P level.

Did you know ?

Most of the time, burglars will give up trying to break in if the system resists for more than 5 minutes. Hence the value of good protective equipment.
