unlock your keyless car if keys are lost

Hi friends, i am going to tell you solution if your cars centre lock (car open without using keys) key has lost and your car is locked and you have another key at home, but you far from home or any other circumstances that you are unable to reach home. So the trick or solution that is i am going to tell you will definitely help you. The trick is that, you have call anyone who is at home and know or search where the keys are. During the call tell who is at home to press the unlock button and you have to stand near the driver window (near about a feet). If it is not working then change your direction a little bit and tell him/her to press it again. I assure you it will definitely work. If any problem contact me or post a comment, i will help you.
Friends, its my first post so please give a reply how's it and what are the mistakes and any improvements.
Thank you.
