There are several possibilities of why this happened.
The two most likely are:
1) Keyboard connection came loose.
SOLUTION: Reattach the connector. This is easy, especially as you know how to tear down the phone. There are many videos available that show how this is done.
2) Keyboard cable is damaged
SOLUTION: You will have to replace the keyboard in this case. They're about $9 online, so that's not too expensive.
Good luck.
