This is a relatively low poly lock. There's a pretty involved keyhole, but if you get rid of that the Polycount should go way down. Also, all the modifiers have been applied on the exports, but if you get in touch with me, I can send you a version without the modifiers applied.
You want textures? They're all there! You want it fully unwrapped? It's unwrapped and ready for the aforementioned textures!
You want Blender file with all the images packed into it? You've come to the right place!
You want high quality locks and low low prices! Sold!
