Unlock your car with a cell phone.

You have locked your keys in your car and you are out of state, what do you do? This will only work if you have a newer vehicle that can be unlocked with a remote button.  It will not work on my old classic car that is shown in the photo.  Call home or to whoever has your spare remote button.   Hold your cell phone up to the car lock. Have them hold their cell phone up to the car lock and push the unlock button.   We first tried with the regular phone and it did not work, so we then tried with a cell phone and it worked.

Let me know if you try this.
