M.A.G. (Medeco) Ultra 800 deadbolt lock

[bayer2]

I need to swap out the cylinders from 2 Ultra 800 locks (vintage 1982), one a double cylinder and the other a single cylinder with a thumbturn on the inside. I can’t find any set screws, even on the thumbturn, and there are no screws or anything readily accessible behind the deadbolt plate, at least not that I can see. I would appreciate any suggestions from someone acquainted with these locks.

Start at the lockset at the door edge….

Remove the decorative plate……under that you will find a setscrew(s)…….back the screw(s) out and you’ll be able to unscrew the deadbolt on the face of the door…….

YMMV

“…measure once…..cut twice….throw that one away and cut a new one….”

I’m no locksmith…..I’ve only dealt with ONE problem deadbolt……..

Did you read the previous “LINK” about the Long 3/32″ allen wrench ?

Here’s another reply/post here at BV with slightly different information:
