Key Retainer Devices (KRDs) are in the industry forefront as a proven way to prevent crime by providing visual authorized accountability. This means that as a Top Master Key is issued for legitimate purposes, the employee's  key is temporarily "retained" in the KRD. When they return and replace the Master Key, the employee's key is released and the Master Key is again locked into place. This procedure accentuates safety since accountability is required and Master Keys stay "on premises." Thus, potential crime and security vulnerability is lessened.
