Don't remember where is the car key or door key you put it on? Wasting much time for finding keys or other objects? 
This anti-lost finder can help you to locate objects. Just attaching the receiver with your key or other objects, then you will not be upset anymore for finding the key or anything precious. If your key or baggage, or other object is hiding at somewhere, you only need to press a button to trigger the alarm sound from the receiver side, making it to be easy 
found for you. This wireless key finder uses the latest electronic wave search technology to locate your keys and will work up to 20 meters.
