Outclasses. Outlasts. Outperforms. E-Plex® 5000 Series makes upgrading your traditional keyed-in locks or mechanical push-button locks easy. This lock combines the strength, simplicity, and reliablity of the distinguished Kaba Simplex®, with the enhanced security and convenience of stand-alone electronic access control. You and your staff can now use secure codes for access. And since the E-Plex 5000 auto-locks, you gain assurance your doors always stay locked. This adds another layer of security to protect the people, and confidential and/or private information in the spaces behind those doors. Does this lock require AC/DC current? Nope. It saves you on the ownership costs of implementation and installation with its fully battery powered design. You can get up and running in less than hour time. "I've never heard of Kaba, who are they?" Glad you asked! Kaba's track record for making first-class locking technologies goes back to the 1800's. They rank as the largest provider of access control products in the world.
