key finder
Lost item locator
A key finder is a small electronic device that helps locate lost keys.
Most attach to a keyring and emit a beep or flash when triggered by a remote, smartphone app, or clapping.
Some use Bluetooth to show the keys' last known location on a map: I finally got a key finder after locking myself out twice.
