I thought keyless remotes sent RF signals, not sound. Is this possible?If you lock your keys In the car and the spare keys are at home, call someone at home on their cell phone from your cell phone. Hold your cell phone about a foot from your car door and have the person at your home press the unlock button, holding it near the mobile phone on their end.
Your car will unlock. Saves someone from having to drive your keys to you.
ETA: Never mind; SNOPES says FALSE.
