CyberLock brings effective access and key control to narcotics safes on rescue vehicles and in firehouses. Simply replace the mechanical cylinder in the existing narcotics safe lock with a CyberLock electronic cylinder. The CyberLock electronic locks and keys store an audit trail of openings and unauthorized attempts to enter. This audit reporting can be very valuable to management. Each key can be programmed with the access permissions of the person responsible for dispensing and inventorying drugs. Keys cannot be duplicated and the locks have no keyway to pick. A missing key can quickly be deactivated and blocked from the system. CyberLock electronic padlocks with the same access and auditing capabilities are also available for securing expensive firehouse equipment.
