Jim B: I am a bit confused as to what you are saying. Do you mean after the paper clip's metal is inserted into the hole, you then wrap the whole paper clip around the whole battery compartment housing? Or do you mean to wrap the shorter piece of metal (after you have cut it) AROUND the actual door and FORCE the door to remain closed (due to the tightness of fit)?

Currenty I am using an inch of duct tape and it works better than I thought, given the strong spring tension to undo the whole thing.
