Has anyone else ever wondered where the blind got there hands on the same technology as the nords to make and implement the locks in there chests that are nearly as sophisticated looking as the nordic or dwemer style?

Yes. Once or twice... or more.

Well, blind doesnt mean you cant fiddle with technology.
Other senses can take the place of sight.
The Falmer seem quite adept at utilising Chaurus chitin for just about anything, they use alchemy and magic as well.

Though I would say that the reason they look similar to the Nordic locks in the game is for gameplay reasons.
It would have taken more resouces to develop two different kinds of locks and lockpicking mechanisms.

What he said, I'm willing to excuse minor plot holes and the occasional cheap plot device if it makes the overall gameplay better

Oh not saying that the blind cant do things. I understand its all about gameplay mechanics, but it would have been could if they maybe made us had to pick falmer locks in reverse or upside down. use the same mini game just swap the code around a little.
