Is this true? 1. If you lock your car keys in your car and have remote locking and you have another set with someone else, use your mobile to ring the person with the spare keys. Hold the mobile close to the car and have the other person press the unlock button on the spare set close to their phone. Open voila. 2. 112 is the International Emergency Number for mobiles. Even if your mobile doesn't have a signal or the keypad is locked then dialling 112 will cause the mobile to hunt any network to establish an emergency connection. Urban myths or the truth?
