The Smart Key Finder helps you track down lost keys in no time. By pushing a button, this intelligent tracking device helps locate one's keys. To use, attach a colored receiver to your key chain. The next time they are misplaced, press the appropriately colored corresponding button and your keys will begin beeping. The wireless transmitter works up to fifty feet away. The battery-powered key finder comes with two receivers and one transmitter.

This device works similarly to the strategy whereby a lost phone is found by calling it with another phone. The sound helps guide you to the correct location. However, if the keys are outside the limit, you won't have a better idea of where they are.
