very large 45 year old sliding glass door

Question

my sliding glass door has a lot of friction as it moves across the bottom "rail" should I try this "slider slicker with Teflon" or how do I learn exactly how to change out the rollers or track.. it is a very big and cumbersome door. I am afraid of breaking into something and not being able to get it back together. There is just a ID of Code 130-2 on the small sticker on the top of the door frame. That is the only ID.

I will not be doing the work..

Cleaning and lubricating the track is definitely a good place to start, but if that doesn't work then it may be time for new rollers. I'm not sure what door it is you have, but see the video below. This shows how to replace rollers in most types of patio glass doors. It may help for your own project.
