I came out of LQS last year and used my key fob to open door of "my" car. When I got it I noticed all these children's books on front seat. Looked around and my car was 2 over. As I am getting out, this lady walks up and I explained what happened. I don't think she really believed me until she clicked her key fob and unlocked my car as well. Found out she purchased her car in Virginia. Called Lexus and yes, it is rare but there are duplicate fobs.
