The mistake was not locking the door. Since they were able to just open the door and walk in, I am sure they were on him before he even woke up. If the door had been locked, where they had to make a lot of noise to get in, he would have stood a lot better chance of getting his gun into play.
It's entirely possible that they were just walking down the street, trying the door handles on every vehicle they passed, looking for an easy score, and if they had found his door locked, they would have simply moved down the street to try the next vehicle.
