When my dad and I repainted my car, we were re-inserting the cylinder/tumbler, and I dropped it. I think I got all of the tumblers, but what would be the easiest way to put them back together? A locksmith would be my best guess.

Also, I am assuming that each car company uses different tumblers, correct? Because my friend works for a GM dealer, and can get them cheaper (I am sure that it saves me a whole dollar on each one), but will these work? I mean if I find out which tumblers I need based on my key, do I have to get them from a Honda dealer?
