Some of this you can handle. Lubricating rollers and hinges, tightening loose bolts on the track brackets, cleaning photo-eye lenses, and reprogramming a remote are all fine to do yourself with basic tools.
Torsion springs are not on that list. They're wound under enough tension to cause a serious injury if the winding bars slip, and that risk doesn't go down because the door is only a couple decades old. If your door won't open, won't stay open, or the spring has visibly separated, that's a call for someone with the right bars and clamps, not a Saturday project.
