They are very fragile keycaps, and are easy to break. But with care, they can be removed easily. We do replacement keys, and we translate keyboards for customers all the time.
This guide may prove helpful in at least understanding how the mechanism works and how to remove it if you've not done it before.
If you're not confident with it though, i'd suggest you look for a tech savvy friend or a company to do the work for you. Its not overly complicated, but does take some dexterity and a gentle touch.
