I'm afraid I'm not totally familiar with this type of hardware. Can I see a few pictures of what you have? This will allow us to research a solution for you.

The door is a pella 450 or 750 series. I am trying to get to the locking mechanism which apparently to acess it, you need to remove a wood stile piece that the lock comes thru to meet the strike. The mechanism is a swisco mechanism part 82-247 .

Thank you for your patience in this matter. To replace this hardware, first you will need to remove both the handle and lock housing cover. To remove the lock housing cover. The cover is attached to the panel stile with several screws. The screws are driven below flush to avert interference with the lock housing cover. All of these screws must be removed in order to free the housing from the lock stile.

Once that's off, the screws for the mortise should be exposed. Simply remove the four screws holding the assembly in place and it should come right out. To install the new one, just reverse the process.
A handy person from Alloway NJ says:
I have removed both the handle and lock housing cover. There are no screws visible for the mortise lock. It appears a stile or trim would have to be removed to access the screws. Possible even the glass itself. Is it possible the mortise lock is a permanent installation on my proline door and it is not servicable?

It is possible that there is a trim covering the screws in certain instances. When it comes to Pella hardware, they do not want to make it easy for you. They would rather you simply replace the door entirely, or send out for a service person to come and do it for you. We don't believe in this, of course, and we try our best to find ways around it, but in some cases it may be unavoidable.

Trim piece. How do I access screws to get this off? Is white vinyl stuck on with adhesive covering wood? A return spring is shot in mechanism it seems so each time I need to close door fully I must use finger to push the catch piece down. It sucks. A simple spring broken or repairable? I want to take out to look at. I'm a locksmith from years past. Maybe an easy fix? Suggestions? I don't want to chew up door taking apart...

I've never personally dealt with this trim piece, but I've seen it from other customers a few times in the past. From what I've been told, you have to pry that tab off at the top and bottom near the opening. But to be honest I'm not 100% sure. I would recommend contacting Pella directly for assistance. Knowing their company, there's always a catch. You don't want to accidentally break it because there's no telling if they'll supply you with a new one. Better safe than sorry.

Thanks for your reply. That smaller white trim piece around latch opening I did have out. It. Carefully pries out. It's there to just dress up the edge of the hole for the mortised latch assembly. When it's out you still can't see any way (screws) to remove latch assembly. (the 82-247 part) I guess I need to try prying off whole edge trim piece from the top down. Hopefully I won't crack it. It appears to maybe be held in place with adhesive but I'd hope not. Replacing whole door is not an option, (as per Tom's reply to another customer) that's ridiculous. I'll see what happens. Thanks again. Mike
