I think we all have at least once. I myself have with my two year old son inside. He did not understand my frantic pleas to push the power unlock button, he was too busy pretending to drive.. Luckily, after some panicking (a good 10 minutes) my husband arrived with a spare set. Well, that was a long time ago. Today, all you have to do, if you have a spare remote entry at home and a cell phone, call someone at home on their cell phone. Hold your cell phone about a foot from your car door and have the person at home press the unlock button holding it near their mobile phone on their end. Your car will unlock!
