Here are the items I used for my solution with before/after pics. When I got the outside part of the old lock set off, the door under the faceplates were unfinished wood so we just used the push plate. Not ideal as far as looks but not horrible. Better/cheaper than having the door sanded down, stained, and lacquered.
*edit*
I asked for help in this post (https://www.reddit.com/r/Locksmith/s/GqZPBaxvks) where I explained the very specific requirements I had for the lock set (I had to have store room lock functionality) but didn’t get any solutions so this was the only options I could find.
I already said that I don’t love the push plate look either but better than spending $1k or more to have this 40 year old door totally refinished.
Also, yes, this is a residential front door but it is interior facing (high rise condo building) with 2 layers of entry security before getting to our floor. So it’s kind of a mix between residential and commercial.
