Has anyone ever rekeyed a Morton building with the alumasteel locking system? I have a job coming up to do one and the customer said she had another locksmith out and he took most of the door apart before she kicked him out. I'm looking at the video of the system and it isn't clear how much dis-assembly will be required, but certainly, some will be required. It appears to be a typical Schlage deadbolt - so once I get to the mounting screws it should be fairly straightforward.
Here is the youtube video

and here is the Morton page describing the system
