I need to remove our push pull style drain stopper in our bathtub so I can get the snake the drain. I've looked at several videos of all seemingly different style lift and turn stoppers, and none have helped.
Here are the best pictures I managed to get: https://imgur.com/a/xSqYB8g
Some info about the stopper:
There is no screw under the cap/knob.
There is a ball bearing on the post/rod that depresses when pushed shut (spring-loaded?).
The cylinder holding the rod has a flat side, but is inside the drain itself. The ball bearing doesn't act differently when turned to this part of the cylinder.
The cap looks like it's screwed onto the rod, but the opening is barely large enough to get needle nose pliers in. I have some small vice grips, but the nose is too get a good grip on the center rod.
The cap + stem rotates when turned, whether popped up or down
I think the drain/tub assembly are from Danze, but a lot of the other drains in this house are Kholer, but I couldn't find any useful information regarding this style stopper from them.
Any suggestions? Short of dissembling the pipes or ripping it out with a crowbar, I'm kind of out of ideas.
For what it's worth, the stopper in this question is likely the same, but the accepted solution was to use a plastic drain stick, which I've already tried: How do I remove a push-pull tub drain stopper? . Also, it doesn't actually answer the question: how do you remove this stopper?

EDIT: I never managed to get the stopper out. I think to remove it, I would have to take @Programmer66's suggestion to go in from the access panel in the hallway and open up the drain pipe to remove it from there.
Since my plastic drain stick was coming up clean, but was long enough to reach the end of the drain itself, I figured the clog was further down than that. I removed the cap on the overflow drain and used a 15-foot drain snake to remove a hair clog deeper in the pipes.
