Have you ever heard about how you can unlock your car by having someone transmit a signal from a spare remote key via your cell phone? Pretty cool, huh? Well, it doesn't work. Keyless remotes and cell phones operate on completely different frequencies, so don't plan on this trick ever saving the day the next time you lock your keys in the trunk. Regardless, I've heard this urban myth so many times over the past few months that I even started to believe it might work. That is, until I saw it busted with my own eyes on perhaps the greatest show known to mankind—Mythbusters. Seriously, I can't get enough of the Discovery Channel.
