Those individuals are known as THIEVES. Or best case - pranksters with too much spare time. All they have to do is just drive by a parking lot, garage structure, or area with lots of curbside parking, and they are in Six Flags as far as potential valuables is concerned. And yes, sometimes unintended doors open - such as the fuel door.

It's been more than 5 years ago that this would work. Years ago there were just a few channels in a frequency band that were used for garage door openers. One frequency for open, a slightly different frequency for close. That was pretty easy to defeat and only required a frequency counter to be present when the target opener were used. A sweep generator could also be used to open the doors then, but this took time. The amount of time was reduced if you knew the brand of opener that was installed. But as openers became more common, then automotive remote keyless entry, code hopping was implemented. The carrier frequencies are shared among many users, each with their own codes. You no longer can just select a frequency and work a modern keyless entry system. Code hopping has been commonplace in these systems for at least 10 years, probably more like 15-20 years.
