Knox Box

HCESD48 has officially implemented the Knox Rapid Entry System as the standard for emergency access to commercial properties.

This high-security key system is designed to provide firefighters with immediate entry to locked buildings or secured areas during after-hours emergencies when the premises are unoccupied. Rapid access during emergencies is crucial for safeguarding lives and property.

The devices you order will be shipped directly to you from the Knox Company. Depending on the specific device, it may arrive either locked or unlocked. These devices are uniquely keyed to the Department, and only designated units within the Department will receive the necessary keys.

Please follow the installation instructions provided with the device. When you are ready to activate the device, you must contact us for assistance in securing it. This process ensures strict key control and informs emergency crews of new devices in their vicinity.

Knox Boxes installed within the HCESD48 boundaries must be keyed to the appropriate lock. If your lock does not match our key, you will need to submit a Knox re-key form signed by our agency. For assistance, please reach out to us at: (832) 739-6515.
