My kids are both escape artists also. We went to Lowe's and bought some latch locks. They swing over the door, over a bar with a rounded end, and a pin slips in it also. You don't have to use the pin. The ball at the end allows the door to open, but barley wide enough for a hand to go through. If you put the pin in, the door won't open at all. We put them at the top corner of the doors, the garage, the frontand the pantry, I can barely reach them. We also bought these pins for the sliding glass door, I think it is calld a sliding glass door lock. You will have to drill ahole in the frame, but it works great. The pin slides the bracket, there is a notch. You have to have the notch lined up just right to pull the pin out. We put it at the top. It might even work on windows. These locks work great for us.
