Why are my interior lights going on and doors are getting unlocked on occasion
What occasions? A little more detail, please. Does this happen when you are watching but not pushing the unlock or lock buttons on your remote? Or has it happened and someone else told you it happened? How do you know this is happening and what are you doing when it occurs?
Because something in your pocket is pressing the unlock button on your key fob.
Could be dirty corroded battery connections. Pull off the cables, clean the terminals and battery posts, and reattach the cables.

Interior lights can come on b/c of a faulty door switch, but that wouldn’t explain the door unlocking.
