Keyless glovebox security for your on-road vehicle. The latch unlocks when the vehicle wakes (start button) and a valid DESS key is detected"no need to start the engine or use reverse throttle. It relocks when the vehicle is turned off. If the DESS key is pulled while running, the engine keeps running and the latch stays unlocked; once the engine is off, it locks when the key is removed or after ~30 seconds.
