Lego glue kid has a product that is a great play for Lego themselves to license. Put a small bit of glue in those kits so the kids who built a Millennium Falcon or Hogworts can keep it together. This wont make them a bazillion dollars, but it will pay for those two kids to go to college.

I really had a problem with the front door lock guys, This only works if UPS/FedEx/USPS etc. climb on board. And I don't see any real advantage for them to do this. Only way I can see it working is to give the carriers a royalty for every package they scan and leave locked. And I don't see that happening.
