Fechadura e chave Modelo 3D

Simple pad lock with accompanying key.  If you edit the lock mesh and check in the Object Data (I believe) tab, there is a set of vertices called "hook" - click it and click select and you'll have the hook selected to pull out and twist as needed for whatever image you are working towards.  I haven't made any shapekeys as I have no plans to use this model for anything other than a couple stills in story I'm working on.  Dig in, have fun.  I actually only made it because I made the key first (having not found a simple key model out there to tinker with.)
