Don't pay a car dealer $250 for a key FOB replacement. ACE hardware can do it for $20.

My wife's Lexus Key FOB broke. The dealer wanted $250 for the replacement which to me was ridiculous. I went to ACE hardware and they have KEY Fobs for each make and model. As long as the "guts" of your key FOB are working, they can be dropped into the replacement key FOB. Then they just grind the key part to match your spare. End result cost $24 bucks with tax, and it works like a charm. Don't make the dealer richer than he is.
