So my wife's new car uses the new key-less entry and start system that is so popular these days. (key in your pocket, walk close to car and it unlocks, push button start, key never leaves pocket) Unfortunately I already lost the second key on the beach this past summer, and replacing the key will cost me an arm and a leg. I know the RKE systems use low frequency radio signals to preform these actions, and that cell phones operate on higher frequencies. What i am curious about is the possibility of using the new NFC technology, or something similar to duplicate the signal typically put off by the fancy key. I am pretty sure nothing does this today, because i have searched quite extensively, and all i find are the silly stories about sending the signal through cell phone calls, which is bunk. Has anyone heard any talk of such an idea. Seems smart since i could almost never loose my cell phone, and it will always be with me, thus killing two birds with one stone. Thoughts?
