Hey, sometimes you just have to try stuff for your self. Nothing wrong with that. It helps the learning process. Good experiment, lab work and documentation by you, in my opinion.
Don't feel bad. You were trying to help folks.
The phone can only re-produce sounds through the speaker, not radio frequencies, which is what the car key fobs use.
If you really need to unlock your door, cut a hole in a tennis ball. Put the hole over the keyhole on your car door to make a tight seal. Slap the tennis ball against the lock as hard as you can to shoot a jet of compressed air into the keyhole and the door will unlock. It has to work. I saw it on an internet video.
I think Myth Busters did that one, too. They had a very hard time making it work. Why? Because the stream of fluid is not laminar. It has many breaks, or air gaps, in it. But you are welcome to experiment and tell us the results.
