This Pin has lots of great ideas. Using nail polish to distinguish your keys is one of those "why didn't I think of that" ideas. I started painting the extra keys to our house that we've given to others so that they'll know that they're ours. I've had friends/family do one of two things that drive me batty: 1. they forget whether we've given them a key - and they certainly don't know which is ours! 2. they put our name or address on the key - hello, burglar, here's where to go! The nail polish has been a simple solution to avoid these problems!
