Commercial buildings

There comes a moment in practically every company when we are faced with the situation, where we lost track of who has access to the premises, where the keys are, and most often, that we have to take a large set of keys with us to visit the company’s premises.

We have a range of successful applications for security of commercial and industrial buildings within the Securidev group.

DOM, DOM-TITAN, DOM-RONIS, DOM-METALUX, Euro-Elzett, Metalplast, Deny-Fontaine, DOM-CR and Picard-Serrures offer solutions to your problem.

The solution is the Master Key system – MKS

There are several possibilities: from simple to safer options, with patented keys or even electronic cylinders, which can be connected on or offline.

We offer locking systems in basic cylinder versions with 5 pins and a special profile, in safety version with 6 pins and a special profile, or in T100 system, as well as in systems with DOM-TITAN and DOM patented keys.

The process of choice and making of the locking system is as follows:

Firstly, we select a desired system in the locking system plan. You can make the plan yourself, however, we prefer you make one together with our experts.

In the locking system plan we determine the number of doors and the size of the cylinder on one part of the table and the number of users on the other. By name based authorization (we can determine by name which person opens which room) we get a table, which is the basis for our calculation.

The system is given a code number and thus equipped goes into our production, and all acquired information is treated as business secret.


The client also receives the owner’s card with the locking system, which is the basis for all further orders of keys or upgrades to the system.

The simplest locking system is the key alike system – KAS 

Poslovne zgradbe 9

This is a locking system suitable for more doors, which lead into one room, or more rooms that are used by the same users – we use different cylinders or sometimes padlocks, which open to one key only. This system can also be used if we have premises on different locations.

Central key system – CKS

This system is designed for main entrances into commercial buildings and other common premises, such as toilettes or similar. Each individual can unlock the rooms determined in the locking system plan with a key to their office, however, they cannot unlock other rooms, which are not a part of this locking system plan.


Upgrade to the previous system is a simple master key system – SMKS.

This system enablePoslovne zgradbe 11s unlocking of more rooms, which are otherwise unlocked individually with separate keys, also with one special, s.c. MASTER key. This is often used within a department, where every office has its own key, and the head of department has one key, which unlocks all the offices


More systems can be linked into one, bigger locking system, which is the grand master key system – GMKS.

Poslovne zgradbe 12

We recommend this system for larger facilities, which are divided into smaller units, as well as for the companies, that have their production organized in separate locations. Each individu

al has its own key and the access to the premises according to their authorization. All of the above stated locking systems are possible within this particular one, and in the end all the cylinders are unlocked by one key, the so called master key.

A similar solution is also offered by DOM Protector cylinder with an electronic knob for the control of access and locking systems.

Simple installation:

  • no cabling
  • no drilling into walls

Anti – panic locks

Poslovne zgradbe 17Some premises, where a large number of people are gathered, especially meeting and conference rooms, cafeterias and similar, need special locks for emergency exits.

The Afora lock is made especially for these cases. Entering the room is possible as usual, that is with an authorized key. The exit, however, is possible with a push on the bar, which spreads along the whole width of the door. The push releases the lock and the door opens automatically.

In the case of fire or similar emergency, when the crowd gathers at the door, the door opens automatically when pushed against. 

Locks for all your doors
