Yep, thats pretty common. Has been like that for a long time.
When I was in high school, one of the guys in our group of friends drove a 63 Chevy Impala..... it was a POS. The ignition was so sloppy from all the weight it had on it that just about any GM key would start the car. So I had a Camaro, another buddy had a Firebird, another guy had a Chevelle, another a Chevy pickup, etc. On any give day, one of us would go out & move his car for him. Not far, just to the other side of the lot. He never had a clue where his car would be at the end of the day.
The Nitro keys have an RF chip inside that would not allow this to happen. But the sloppiness of the keyhole itself is easily caused by a big keychain.
