Trimark latch with twin keyholes: lubrication
The handle was really hard to open after unlocking. Getting more so with time. I took it off the door to have a good look. Three torx 14 screws from inside the MH and two more at the latch. Lubricated with a lithium white grease spray can in several places but the one that fixed it was in plain sight with no need to take out any screws.
Note the white grease on the plastic lever.
I had previous trouble with the handle lock (not the deadbolt) slipping into the locked position on its own. I worked on the inside half of the mechanism, welding the part that pushes the bolt in. I noticed the weld had failed so added some construction glue to hold the shiny lever. This photo is rotated 90 degrees clockwise, sorry.
I also removed the inside lock handle so we wouldn't accidentally overcome the glue and lock it. Another reason for getting rid of the second lock was to avoid fumbling around in a middle of the night emergency. And one key less.
On reassembly, I used Robertson screws so I don't have to carry a torx set with me. I found the screws in the stove bolt section at the hardware store. Had to cut the two for the latch on the door edge a little shorter.
