Carl's story takes me back to when I worked at a repair shop that got a lot of calls to unlock cars, I was amazed how many times they had a spare set of keys for just such an emergency, in the trunk or glove box or hidden under the hood, the record I remember was 5 spare keys plus the set still in the ignition all locked inside the car ! I got pretty good at not laughing til they left, and yes, there was a charge for that service.
