This post has come up a dozen times on half a dozen forums.

The Touch Pro Keyboard is very flakey. The Keyboard is covered under Warranty which as of April 09, Sprint honors in store. You do not need TEP for this; nor need to pay anything out of pocket.

Back Up your Touch Pro, bring it to a sprint store, and they will either repair the keyboard or give you a refurbished phone.

I account this issue to the connector between the keyboard and the phone unit overheating; as the phone achieves temperatures that can render other pieces of its hardware unusable. However both HTC and Sprint deny any real product flaw.
