Unlocking a car with your cellphone
On a radio talk show this morning, one of the DJs had accidentally locked the car with the keys still in the ignition. A listener called in, claiming that he'd gotten out of a similar jam by calling home and having his wife hold the spare "clicker" up to the phone and pressing "unlock" while he held his cell phone a foot from his locked car. A "poor man's onStar." The guy sounded legit, whatever that's worth.
Would this really work?
