Actually, just a regular magnet can screw up a few devices, for instance the tire pressure monitor system in my Jeep. The driver information center says, "please remove magnet from spare" //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif. Usually you should be alright.
