Be careful on the screen door rollers. The replacements I got are made of tinfoil. Too much adjustment and you round out the threads on the little screw doodad.
The sliding glass doors rollers are an interesting type. Mine were all stuck/rusty but a little PB Blaster and a little disassembly & cleaning they were fixed. If I recall it is just a bolt with a chunk of metal that when tightened rides up piece of angle like metal. This pulls the wheel up or down if loosened. Now the doors slide a little too easy.
After that I could actually adjust the doors and make them close evenly. This resulted in being able to lock the doors with ease. Don't have to worry about twisting off the key.
