CyberLock offers a powerful and affordable solution to help law enforcement agencies control and audit access to their evidence and property storage rooms. A department can quickly convert door lock hardware to a full-featured access control system simply by replacing the mechanical cylinders in existing locks with CyberLock electronic cylinders. These cylinders cannot be picked and the electronic keys cannot be duplicated. Each key contains permissions on what locks the key can open, with a schedule of days and times it will open those locks. Each time the key opens a lock, a record is stored in both the key and the lock, creating an audit trail of openings and unauthorized attempts to open a lock. The CyberLock system eliminates worries about lost keys because a missing key can be quickly inactivated.
