You're doing all you can, and more than most people would do. You've chipped him, which is probably the #1 thing you could do for him. He's wearing a collar, so it's no secret that he has an owner somewhere who cares about him, and increases the chances that even a casual cat rescuer will have him scanned.
Cats, being contrarians and all, tend to not appreciate coming home and finding the door closed against them. If Boris is the talkative type, this might be all he needs to start complaining loudly, thus announcing his return. (As opposed to taking it for granted that the door will be waiting for him to return at his leisure).
Mind you, I'm not a cat owner. I've lived with one for a while, but only have his behavior to go off of.
I'm more concerned with how your door came to be open in the first place. Is it the kind of knob/handle a cat could conceivably open by jumping at it? Did local kids possibly open it? Is it not shutting right?
