What about some kind of appliance-strap style device? They are self adhesive typically, so you don't have to drill. You could probably use the 3M removable adhesive. As pp have said, not burglar proof, but certainly toddler proof. We also have our alarm set to chime and announce which door is opening. That way if our back up locks aren't on, we at least hear what's going on. I think they make adhesive magnet sensor alarms that you could add.
