Good news if anyone is following. I finally got the Trimark 650 lock off and my door open.
After finally getting the inside cover plate off, I was able to understand how the locked worked. The deadbolt is straight forward. Operation can be confirmed in the upper right corner. Deadbolt unlocked. The latch was not retracting. The white spring loaded arm was not retracting the latch. I could see the small arm in a small slot to the right of the plastic arm.
Disable the spring and while pulling/pushing the door, I was able to get the sharp point of my pocket knife dig deep enough (soft pot metal) to pull the latch back, opening the door. I took a short video but can not upload.
I can upload pictures if anyone is interested.
The 1650 lock is on order and I hope it is a better lock that the 650.
The cover is sandwiched between the door and screen. You can reach all 3 screws than wiggle, jiggle, a little bend back will allow enough room for the latch lock to slide off the shaft.
