The two key systems useful for anyone who has a shop

A shop may have a rather complex management of the keys. Typically, there are various locks: shutters, entrance door, doors to offices and storerooms, secondary entrances or gates, security grilles and gates. If each lock is managed independently the bunch of keys soon becomes very bulky, and inconvenient to carry and use.

It can therefore be very convenient to open all the locks with the same key, thereby reducing a large bunch of keys to a single one.

And, as if that wasn’t enough, all these locks must often be operated by different people: owner, shop assistants, administrative staff, suppliers… which adds a further layer of complexity and possible confusion. In this case it may be useful to be able to give each person or group of people a key which only opens certain doors and not others.

Open all locks with the same key

This is probably the useful solution in the majority of situations. A typical case is that of the various roller shutters of a shop, where it is very convenient to be able to open the locks, padlocks or fastening units which close them with a single key, rather than having a bunch of keys which are all different from each other, as they are more cumbersome to carry and more fiddly to use, since it is necessary to find the right key for each lock.

But you need not limit yourself to the locks or padlocks of the roller shutters, as it can also include the locks of entrance doors  and interior doors giving access to offices, storerooms or other areas. You can also manage drive-through gates , pedestrian gates, grilles and security gates. If the system is well designed (for example, using all locks that work with a profile cylinder), you can open all the doors of the shop with a single key. This is very handy, and it is used every morning when the locks are opened and every night when they are closed.

In order to open all the locks with the same key they merely need to be selected so that they can be included in a keyed alike system (KA).

Of course, the various locks must be compatible with each other. Many Viro products (cylinders for mortise locks, padlocks, locks for garage/gates etc.) lend themselves to the creation of a keyed alike system. For example, all the locks designed to work with any type of profile cylinder can be part of the same keyed alike system (KA), simply by choosing and installing cylinders with the same key in the various locks. This possibility is clearly indicated in the pages of the various products shown on the website www.viro.it by the wording “standard KA executions are possible” or “all special executions are possible”. A keyed alike system can be requested directly from the Viro retailers for a small surcharge, which pays for itself alone when you need copies of keys, since each product comes with its own set of keys which are equal to each other and duplicated at source.

Ensure that everyone can only open locks for which they have authorisation

Often it is not necessary that everyone can open all the locks, but, on the contrary it is necessary that some people can only access certain areas. For example, the sales staff must be able to open the shutters and doors to the shop, but maybe they should not have access to the offices. The regular suppliers must have access to loading/unloading areas but not to other areas. The owner or the manager must, on the other hand, have the ability to open all the locks.

In these cases it is possible to use a master key system(MK ), where there are 2 levels of access. The master key, which opens all the locks, and individual keys which open a single lock.

A master key system can, if necessary, be integrated with keyed alike systems, so that individual keys can open more than one lock.

In this way, the owner, the manager or whoever is in possession of the master key can open all the locks with this key, whilst the persons in possession of individual keys for locks that form part of KA groups may only open locks for that group.

Also in this case there are many Viro products which can be included in a master key system. This possibility is indicated in the product pages of the website by the term “all special executions are possible”. As for the keyed alike systems, the master key systems can also be requested directly from Viro retailers.

Conceiving and creating a keyed alike or master key system may seem more complicated than buying and installing individual locks, but one must merely rely on a good locksmith or qualified retailer in order to resolve the issue smoothly and set up a system which greatly simplifies the everyday life and improves security by implementing several access authorisations.
