Lost key and key fob in house

My wife lost a key(with chip) and a key fob in our house for a 2004 Camry. Is there any way to send a signal to the key fob or key in order for us to track down its location? I understand that the key fob does emit a low signal of some kind.

I don’t know of anything like that on the fob. You will either have to find the key or get another one. Ebay is a good source for fobs at lower costs than the dealer would charge. The dealer should be able get you a key code to make another key.
