Hi, I think my patio door lock match 82-055K, but it is different side of the picture on the page you show, so I am wondering if 82-055K can use for both sides?

Yep, you can just flip the 82-055K around. Just make sure to pop the latch out and flip that around, too, or else just reverse your keeper. Whatever's easier for you.
