Child lock for bathroom key

If your bathroom door (or any door for that matter) is equipped with a key and not the usual 1/4 lock, and you fear your kids will lose the key, then this is for you.

Once in place, the key can't be removed without disassembling the door handle plate.

Do not forget to saw a slit at the tip of the key in order to be able to unlock the door from the outside with a screwdriver, as with other standard bathroom locks

WARNING : you need to edit the STP file, because this is very dependant on you lock dimensions, so my stp part certainly won't fit your door. My keyhole was not even centered with the hole in the door panel. Here the general idea is more important than the 3D file itself.
