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.

For thePoslovne zgradbe 9 apartment, basement, garage, maybe a weekend house or business space you can use the key alike system. According to your needs we can make several cylinders of different sizes, a padlock, a lock for a metal locker or a postbox for the same key, and with that you can order the necessary number of keys. You can always extend this type of system. It is suitable for all the premises that you and your family use.


Central key system – CKS

This system is designed for main entrances into residential buildings and other common premises, such as bicycle room, attic and other. Each resident can unlock the rooms determined in the locking system plan with a key to their apartment; however, they cannot unlock other apartments.

It can be combined with the key alike system, so that your key unlocks common premises in addition to all of your rooms, whereas other residents can unlock their rooms and common premises, and not yours.

Do you have business space, which you wish to open with the same key as your apartment, whereas, you do not wish your employees to have access to your private premises? In this case your key is the master key, and you have a separate key, that opens only the business premises.

You can do similarly in a case, when you wish someone to have access to a part of your property, not to all of it, for example the key to a weekend house, garage and similar.
