Have you locked your keys in your car?
If your car has remote keyless entry, this may come in handy someday. 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).
Editors Note: It works fine! We tried it out and it unlocked our car over a mobile phone
