locked the keys inside


I locked my keys inside my teardrop yesterday. It was late in the day and I stepped outside for a moment and as soon as I closed the door I knew I forgot the keys inside. I have an extra set that I keep in the coin tray in my car but the keys to the car were also inside the teardrop.
To make a long story short I began to attract attention as I was trying to "break in". Within a few minutes I had a dozen visitors and just as many tool boxes with all kinds of instuments to break inside. One guy said why not try someone elses keys. He looked at the lock and looked at his keys and inserted one. To everyones surprise it opened the lock.
Did I luck out or what?

P.S. I now have the key code on my car door memorized so if it happens again I can get inside my car without a key.
