There are three suppliers for Thinkpad keyboards:
NMB,
ALPS, and
Chicony. You can identify which one you have (or which one you want to order) either
visually or by the
FRU number:
You can
look under the keys of the keyboard at the pad/switch color and design to identify your keyboard manufacturer. This can be done by either removing the keyboard or using a paper clip to gently lift the bottom edge of the right arrow key.
You can look up your keyboard's
FRU number using your 4-digit Machine Type (ie:
2081-CTO) and Serial Number
here.
At this point, these distinctions apply only to the "traditional" Thinkpad keyboards, and not the "island-style" Thinkpad keyboards (Edge, X1x0e, X1)

In earlier Thinkpads, Lenovo/IBM has labeled the columns on the Keyboard Service Parts pages, so I've left them out here.
To find these listings, search:
