A single key for everything! You can secure your doors & gates with just one key. The »little master key system« from IKON makes life much easier. The thick bunch of keys people usually carry around is replaced with a single key. It can be used to open and close all doors and gates, from the garden gate, the letter box, the house or apartment door, right through to the garage, cellar, appliance room etc. If you like, a holiday home or other buildings can also be covered with the universal locking system. This practical setup can be achieved with all locking cylinders from IKON. You can therefore combine maximum security with convenient handling of your security measures in all parts of the home and outside area.
