We complete our aluminium and PVC joinery production with high quality safety locking systems. We offer various locking systems:

  • general key system (one key unlocks all cylinders)
  • group key system (one key unlocks a certain number of cylinders)
  • individual key system (one key for one cylinder)

The general key system is particularly appropriate for buildings with multiple residential units as well as larger business premises because every user has a single key which opens their flat, office or another room, and all communal areas.

Along with mechanical locking systems, we are also able to offer electronic systems to larger companies, institutions that require special security measures, hotels, and similar, such as the electronic key system which is protected by a modern encryption technique that offers countless possibilities (software based user authorisation) and card based access control, or entry and exit control.
