KESO Ultra

The most secure cylinder in the world

Nothing is more secure than Ultra: Even in continuous use, it offers the highest burglary protection, the highest reliability and maximum copying protection. The cylinder can only be opened with original keys.

The KESO Ultra is the best choice for anyone who doesn’t want to worry about their security: the cylinder contains special carbide inserts, which make drilling or milling virtually impossible. The web of the cylinder is also optimally protected against pulling through the use of chrome-nickel steel. This means that the valuable things in life are simply Ultra-protected.

Other benefits:

  • Patent valid until 2034 means more security for you: no unauthorised key copies can be made – duplicate keys can only be produced legally with the security card.
  • As part of the KESO 8000Ω2 family, KESO Ultra can be integrated in already existing KESO 8000Ω2 locking systems within your building.
  • Tailored solutions for your building by combining them with mechatronics: KESO Ultra can be combined with mechatronic elements at any time. Whether you want to equip outside or inside doors, KESO Ultra fits everywhere. Simply choose the solution that best suits you and your needs from our comprehensive range.
  • Easy management of your locking system in combination with mechatronic elements through one single software (k-entry)

For your home and for vaults, jewellers, law firms, medical practices and pharmacies, the KESO Ultra is the most secure cylinder in the world and offers the best protection!
