I tried to learn the home row touch-type in my teens and never got the knack, but I basically got used to what I had been doing since I was a kid and developed my own instinctive 10 finger method that I would be hard-pressed to describe in any detail. I used to look at the keyboard a lot but I eventually realized that if I forced myself to look at the screen I did just as well, and it was only a question of breaking the habit.
I think one thing that "helped" my typing dexterity was that my first computer didn't have accent keys in any way, so if I wanted, say, "é", I had to resort to raw ASCII character codes and type in ALT+130. When many very common characters in your language require memorizing multiple sequences of four keypresses, it kinda puts your determination in the crucible.
