Simple. Smart. Scalable. Upgrading your traditional key locks or mechanical push-button locks is easier than ever with the E-Plex 5200 Series. This lock combines the strength, simplicity, and reliability of the distinguished dormakaba Simplex, with the enhanced security and convenience of programmable electronic access control. You and your staff can now use secure codes for access. And since this is auto-locking, you can be assured that doors will always be locked. This adds another layer of security to protect confidential and/or private information in the spaces behind those doors. Does this lock require AC/DC current? Nope. It's fully battery powered, saving you on the overall costs of implementation and installation. You can be up and running in less than hour time. "I've never heard of Kaba, who are they?" Glad you asked! Kaba has been around since the 1800's making first-class locking technologies. They are the largest provider of access control products in the world. Note: This lock is programmable through dormakaba E-Plex software only.
