Query: Cool stone, bad lock!

I bought this necklace for my wife and she loves it. The globe inside is a deep blue, and the continents are made up of different stones. The quality of the chain seems good, and the globe is not too bulky, so she can wear it comfortably without feeling like there is a giant ball hanging around her neck. The bad thing about this item is the lock that keeps the stone globe inside the case. It is just a little tab that clicks into a hole, but either the tab is not big enough or the hole is not deep enough. We have had the globe pop out five times now. Luckily it's been in the mall or while we were walking through a parking lot, so we were able to retrieve the globe every time. My wife is scared to wear it out of the house now, so it is just sitting on the dresser until we figure out how to rig the lock to make it hold better.
