Low-cost door key with switch sensor indicator to detect dead bolt lock status
A low-cost switch sensor remote dead bolt status indicator includes a switch sensor within a key body of a door key which starts a sensor at a door lock location upon sensing of a dead bolt entering into a locked position. The sensor is provided with a self shut-off feature operating after a fixed duration of minutes length has elapsed. The indicator also includes a receiver in the hand held key, which is capable of receiving signals from the sensor after the user presses an inquiry button on its surface. The hand held key has two indicators for alternately displaying the lock's dead bolt status as being locked or unlocked.
