A multi sensor detection and disabling lock system includes detector cases for holding interchangeable detectors that sample for chemical, biological and radiological compounds, agents and elements, with each detector case disposed in or upon the monitored product whereupon light alarm indicators (color coded) on the detector case light up when a specific compound or agent is detected whereupon the detector case transmits detection information to a monitoring computer terminal and transmits a signal to a lock disabler engaged to the product to lock or disable the product's lock thereby preventing untrained, unauthorized and unequipped individual's from gaining access and entry to the product, and also preventing further contamination of the area. An authorized individual resets the detection system, and the system's power source is electrical, battery or computer generated. In addition, the detection system can be interconnected to surveillance towers scanning detector cases disposed at seaport docks, freight depots and rail terminals for monitoring containers being prepared for shipment or sitting on docks for long periods of time.
