Have you locked your keys in the car?

Does your car have remote keyless entry? This may come in handy someday. Good reason to own a cell phone: If you lock your keys in the car and the spare keys are at home, call someone at home on their mobile phone from your cell phone. Hold your cell phone about a foot from your car door and have the person at your home press the unlock button, holding it near the mobile phone on their end. Your car will unlock. Saves someone from having to drive your keys to you. Distance is no object. You could be hundreds of miles away, and if you can reach someone who has the other 'remote' for your car, you can unlock the doors (or the trunk).

P/S : OMG, this is so cool. I haven't tried it out yet. Might actually kick off an experiment to verify the hypothesis. Okay, now I shall just wait for my mobile battery to run really low. It's currently on 12%.
