Bluetooth Traffic Cabinet Locks & Traffic Enclosure Locks

The BlueKey™ Encrypted Traffic Cabinet Lock is an exact lock replacement. A simple retrofit design requiring no hardware changes, door modifications or hard-wiring, is the quickest, most cost-effective way to add the accountability necessary to help eliminate tampering, and to help secure the advanced equipment contained within these cabinets.


Majority of traffic signal cabinets are currently locked with outdated and unsecure mechanical locks (#2 Keys) that have a common and easy-to-duplicate key, making these critical points of traffic control vulnerable to vandalism or attack. The days of the #2 – uncontrolled key are over.


With BlueKey, all access to the cabinet is controlled, scheduled and tracked. Always know who has opened or attempted to pen which cabinets and when.
