Hello all,

This is my first post to this forum, and I'm ashamed of the topic. Recently one of the "intelligent keys" for our 05 sedan went missing. I've checked all over the place, and can't find it. Then I was thinking....the fobs transmit a signal....is there a way I could use something to detect that signal? I still have my key, but I have no idea what kind of signal, or what frequency range may be coming out.

I'm also guessing that *if* was able to create something to detect the key, it would only work in a 2-4' radius from the lost key. But it could be a huge help.

Any thoughts?
