I have a 2000 Boxster S and have owned it for approx 8 mo. I have never had any electrical problems personally with the car, but yesterday something really bizarre happened. My roomates were home and they told me that all of a sudden, they could hear a noise emitting from the vehicle. It sounded like a fuel pump and was louder around the cap area. Then they said that my lights turned on in rear and front. Also, the trunk door came unlocked and the main doors as well. Then the car had a constant horn. It was not an alarm sound but just the horn constantly on. He was able to disconnect the battery since the doors came unlocked and left it like that. Today I shut the trunk back and reconnected the battery and as soon as I did the trunk came open again. About a minute later, I heard the same noise which appeared to be the fuel pump. It has a clean carfax and 110k miles. I also have never let rain get inside. I have the only key so I know nobody was able to mess with anything.

What is the most likely scenario here?
