Deny the grandson entrance? Apparently he keeps getting opportunities to do his thing. And I think something is seriously going on with him. He needs help, I would think. Has, by the way, in my opinion, nothing to do with you being materialistic. He’s a thief, he has to keep his hands to his own, no matter the life style or characteristic of the person he wants to steal from. Just because you apparently, in his eyes, and maybe your own, have many valuables doesnt make it okay to take it from you.
