Unlock your car door with your mobile phone

what do you do if you locked your keys inside your car.

i will assume that there is a spare remote key at home and there is some one there, your wife for example, if this is the case then all you have to do is:

1- call your wife for example and ask her to hit the Unlock button on the remote key while she is talking to you on the mobile phone.

2- on the other side you will be holding your mobile phone near the car, and try to be close to the sensor that communicates with the remote key.

3- The door will unlock.
