Check this out. It is very interesting! i tested it and it works, ps also works on automatic gaurge doors
1. Emergency Number : The Emergency Number worldwide for Mobile is 112.
If you find yourself out of coverage area of your mobile network and there is an emergency, dial 112 and the mobile will search any existing network to establish the emergency number for you and interestingly this number 112 can be dialed even while the keypad is locked. Try it out.
2. Keys Locked in the Car? This may come in handy someday. Good reason to own a Mobile Phone: If you lock your keys in the car and the spare keys are at home, call someone on your mobile phone. Hold your mobile phone about a foot from your car door and have the other person at your home press the Unlock button, holding it near the phone on their end. Your car will unlock. Saves time for someone to drive your keys to you. Distance is not a problem. 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 boot).
Editor's Note: *It works fine! We tried it out and it unlocked our car over a mobile phone!"
Some of us who don't have fancy cars are just going to have to do it the old fashioned way!!!
