Dear OP; before I forget, I have some serious suggestions and some sarcastic ones which I will clearly label to avoid confusion.
Serious: If you're tall, or have a step ladder, drill a "shed" type lock where you can add a padlock, and put it on top of the fridge if or once you have one.
Ask a bar how they do it, the scales previously mentioned sounds like a great idea.
Now for the sarcastic one.
Buy an electric fence and set it to "bear" after wrapping up your keg in rubber / insulator so you don't electrify it ( also I think if you were to do that the electricity would add anions to the kegs and then to the beer and give it a negative charge?? Im no chemist but it's a thought that electrifying it could ruin the flavor, or make it great who knows! )
Good luck!
