ProTool 1 X Magnetic Hide-A-Key Holder - Extra-Strong Magnet (28037)

A service call from a professional locksmith can cost well over $100 - Plus the inconvenience (and embarrassment) of locking yourself out of home or car. Simple to install - just find a hidden area of metal that attracts the magnet (hint: if the metal has rust, that means it contains iron and is 'ferrous'). clean/brush the surface slightly so the magnet makes strong contact. If you're attaching to a vehicle, pick a spot that isn't directly exposed to water or Sand sprayed from the wheels. Also, a handy way to 'exchange' keys if someone ELSE needs to pick-up a vehicle at the airport, etc.
