I'm glad all ended well for you.
Not long ago I accidentally locked the keys in the bonnet at Target. I was with my fiance and she gave me 'the look' then suggested we walk home to get the spare. It was about 6 miles and I knew she'd be too tired and it would take too much time so I called a cab. $15 and 30 minutes later we were back at the Porsche and got her open.
Point of the story: locking your keys in the car happens, and it sucks.
