Doors – How to remove a Mortise Lock and deadbolt from a door


I got an old door from a junk yard that I'm trying to reuse. The door is going to end up being sliding barn door so I have no use for its existing door knob and lock mechanisms. From what I can tell the lock is a mortise lock, and I figured out how to remove door knobs, however I can't seem to figure out how to remove the deadbolt which appears to be connected the interior lock mechanism also preventing it from coming out. There were two screws on each side of the deadbolt lock that I removed, but even after using a chisel and hammer I am unable to remove it. Does anyone know how I remove this and/or the interior mechanism

You need to remove the key set section as pictured on the left. It may be very corroded and require a bit of persuasion to split the halves and remove from the deadbolt assembly. Once you have removed the keyway from both sides, there should be nothing but a couple of screws on the striker/jam plate holding the bolt assembly.
