ENCRYPTED iButton Electronic Keys – Solution to the problem of uncontrolled copying of electronic keys!!! These contactless iButton keys have a specialized LESI cryptographic protocol and CANNOT be copied by locksmits! The encrypted RFID key has a 128-bit code and combines two keys into one. The chip has two parts – a standard part and an encrypted part. This makes it extremely versatile – it can work as an encrypted key in encrypted systems and as a regular key to regular systems. So you’ll only carry one key. The plain part of the chip can be copied and it will work with the regular system, but the encrypted part of the chip can NOT be copied and the duplicates will not work with the secure encrypted systems!

For example, if you have an encrypted control system in your elevator (with BKU519) and a standard system on your common entrance door (with BKU419), the encrypted iButton key can work with both. The standard key can only work with the standard front door system. If someone tries to make a duplicate of the encrypted iButton key, the duplicate will only unlock the standard system, but not the encrypted system in your elevator.

The systems working with this type of iButton electronic keys use a built-in reader, which is metal and is extremely vandal-resistant – it withstands mechanical and electronic impacts, shocks, sticks and glues; is not affected by external climatic conditions. Due to the shape (patented by the Lessi company), the principle of operation and the chrome coating, the iButton reader is best suited for use on external doors that everyone has access to – residential, common entrances, elevators, garages, shops and others. The reader does not consume energy during its operation, this allows the plant to work for a very long time on emergency power.

Another advantage of the reader is that it can be installed directly in the door or cash register, regardless of its material. The strong grip of the reader prevents it from being stolen.
