Recently I received this email: If your car has a remote keyless entry and you lock your keys in the car but someone at home has a spare key; you can call that person from a cell phone; hold the phone about a foot from your car door, have the person at home press the unlock button near their mobile phone and the car door will unlock. I didn't know this and once drove 50 miles to rescue my husband who left the engine running and accidentally locked the door. So he owes me one if I ever do it. Thanks for all the stories.
