can you epoxy the two pieces together? If you can, then test fit it into the door frame where the dead bolt and lock go in. hold the piece with BLUE painters tape (cover the plate complertly) and then try to lock it. if it does not quite fit, brush some "white out" onto the face of one of the lock. the test locking one of the locks real easy and the lock with the "white out" will make marks on the blue tape. you can then either adust where the broken jam is, or you can file/cut a little bit of the lock plates and try it again. once you get both locks to work ok, you can then replace the screws.
