Can you really open your car door using your cellphone?

Hi fello mylotters. I read somewhere that people have done research on this topic. It is said that you are able to open your car using your cellphone? This is great for someone who left or lost their keys. Someone who is very forgetful like me. Haha.. They said to record the sound that the car makes when you press you car key button. I've done that. I've recorded the sound on my phone and tried using it to open my car. But it doesn't work. Did I miss out on any step? Can someone shed some light here?

Your keyfob transmits a code on a radio frequency. If you record whatever sound it makes (which can only be the sound of you pressing the button and the mechanics of the lock at best) and replay it, you are playing a sound file at audio frequencies. The two things are entirely different. You may as well say that you can enjoy a free curry by standing outside a restaurant and smelling it cooking. If you do this, by the way, and the owner complains that you are stealing from him, by all means offer to pay him ... with the sound of your money! There are a number of urban myths about cell phones which circulate in emails and can be found on several YouTube videos. Here is an article, though, which talks sense: http://www.wpxi.com/consumer/15763680/detail.html

Hello, No I think that it isn't true, mainly because when you call someone I don't think it sends anything else, except sound. So I don't think it can send infrared over 2 phones. But I have no idea how the people demonstrated it on YouTube. Make sure you have a good day, Happy Lotting!!
