The Lord of the Keys

Much like Bilbo's little sword that glows when orcs are near, i'd like it if keys would glow when near their lock.

That way, you'd be able to quickly pick out the right key on the bulky key ring. Even in the dark. When drunk.

The other problem with keys is that they frequently misplace themselves. What if you could dial a number on your mobile phone and the keys would start rattlin. Perhaps the keys could SMS you back and say "I'm under the sofa!" or "I'm in a strange dark place i've never been before. I can hear a chuirch bell ringing."

Better still: why not dial a number on your mobile phone to unlock the door. Who needs extra hardware like keys? Would open up a tinful of worms around the security issues though.
