CyberLock
Electronic Locks and Smart Keys
The CyberLock access control system of electronic locks and smart keys provides users with a flexible, affordable, and comprehensive security solution. CyberLock cylinders install without power or wiring, allowing for access control even during network and power outages. Both the lock and key record openings and unauthorized attempts to enter, providing a detailed audit report of all access activity. Keys are programmed for each user, detailing what locks it can open and when, and can be quickly deactivated if lost or stolen.
