Well no, not exactly but instead of using fax to email you can actually open your car by using your mobile phone.
iPhone
The iPhone is already able to do a lot of things from telling you where the closest gas station is to helping you find your way when you are lost. There is already at least one car rental company that have used the iPhone within their business.This company based in London offer their car keys slightly differently, you can use your own iPhone for the kety. Basically instead of using the keys you use your iPhone to unlock the car as there is a special sensor on the inside to pick up the signal from a unique iPhone. They program your phone into that car and you are set knowing that no-one else’s iPhone can get into it.
Normal Cars
If you are lucky enough to have an electronic key fob then you could actually unlock the car with your mobile phone if you have forgotten the keys. You will need someone to be at your home with the other key fob and you will need to get your cell phone at the ready. All that needs to be done now is to get a phone call and put the cell phone right against the sensor. Then all you have to do is tell them to press the unlock button and success you have your unlocked car!
This will only work if you have your phone right up against the sensor so make sure that you know where that is first.
There is another way that you can do this with a mobile.
If you have a business then consider using 0800 numbers and premium rate phone numbers as they could end up saving you a lot of money when it comes to running your company.
