haha i hear that. i think i know those hinges your talking about soss inv. hinges sound familiar? if not you should look into those, also your locking problem can be solved with a magnetic lock, you can operate it with a little button you can put on your keychain. you can get the locks in all kinds of differant strengths such as 600 and even 1200 pounds no body i no can open them if they knew it was there. you mount the lock on the inside of your room, you push the button it cuts the power and the door swings open. you can get these locks off ebay for like 80 bucks and the thing that controls it is like 20 bucks i think.
