My wife has all of you beat , a couple of weeks back she got off early because of the rain storm , she call me from the home patio and said her key wouldn't open the door , I said I will be home in a couple of hours or ride to New Orleans and get my keys , so she went shopping and I called her when I was getting close , we pulled up at almost the same time , I told her to give me her keys , stuck it right in and turn it and it was open , first try , she was locked out for 3 hours --- still don't know what she was doing wrong
