Our company is taking over a warehouse next to our current facility that has been vacant for a few years. The building has three doors that have Schlage Primus deadbolts installed, with no idea who did the installs to possibly get them re-keyed. So, we figure we'll remove them and replace with new locks. I can see no way to easily remove them, I can find no screws holding the two sides together after removing the decorative skirt and the keyway faceplates. How is this lock put together, am I going to have to drill it out? If so, what's the best way to do so? TIA for any assistance....
It could also be that your deadbolt hardware is made by another company and it simply has Schlage Primus cores installed, so these manuals may not help.

You hit the nail on the head, it appears to be someone else's hardware with a Primus core installed. Finally got it sorted after taking the door off the hinges, it has two threaded mortise cylinders, with the securing set screws accessible through the bolt plate. Once I backed those out I was able to unscrew the cylinders, though one was pretty well frozen and required a pipe wrench to get off. Couldn't find any manufacturer info on the hardware, though one of the threaded mortise castings had a patent number 4272974 on it. Patent was issued back in 1979, says that it's currently held by International Security Products and I can't find any info regarding who they are.
But, all's well that ends well and the bugger is off. Thanks for the prompt reply, This site looks like a great resource and bookmarked for future reference.
Are these doors very thin compared to normal doors? That's where I have seen most of these installed in the past.

The door is a cheap metal industrial door with a foam core, 1 3/4" thick. It's an old industrial complex of giant sheet metal buildings, the previous tenant had lots of expensive manufacturing equipment which probably explains the Primus keysets on the three warehouse doors. We're just going to be using the facility for storing packing materials and such, probably just replace them all with cheapo Grade 1 single cylinders for now. The facility will be alarmed and monitored with cameras, so I can't really see spending top dollar to protect cardboard tubes and pallets. Once we start using it for product storage, then we can revisit door security.
Years ago I got to clean up the mess after a criminal broke into a business with one of these locks on it's steel door. I had always thought these were a strong design, but after the mess the criminal made of it, I think a stronger design would have the body (part # 12 & 13) actually a bit larger, so they would take up the inner circumference of the 2 1/8" mounting hole.
This design is also used by Omnia & the removal tool is a long 5/64 hex wrench
