Hi, If by "re" not working you mean note D then try the following.
Keyboard off, hold down top C key while turning on. This factory resets. Does D key now work - if not. Has it ever worked - if not then it could possibly be the ribbon connector between the keyboard and the motherboard. If one of the cables gets bent then this would stop all notes associated with that connection to stop working. This will only have occured if the keyboard has never played these notes or if it has been taken apart.
You could also try the self test mode : Keyboard off, hold C#,F, G# in the 2nd octave up whilst turning on, cycle through tests to sound if it plays all the notes one at a time then the sound chip is ok and it points to keyboard switching. If test mode does not come up in 2nd octave try 3rd octave ( cant remember which one it is from memory )
Let me know how you get on.

Press the FUNCTION button till "Local Control" appears and then select it "On".
It appears this may take quite a bunch of presses to get down to the Local Control option.
Refer to your manual around pages 56 and 57 to see the list you step through. Local Control is about 2/3 the way down page 57.
Refer to 59 for the simple instruction toe set Local Control on or off.

You have to disassemble the case to get to the keys. They LIKELY stay with the bottom of the case. Be careful of the cables from the upper half of the case to the lower.
I am not sure what type keys you have. If these are the semi-weighted piano type, the spring underneath gets out of position... If they are the silicone dome type, the dome may be crushed and you will have to replace the section that is bad. Hopefully the circuit board under that type is not cracked.
The first type mentioned requires some tricks and for that type you MAY have to remove several keys to assemble them in order. I had to make a little "L" shaped piece of metal to get the springs into place. It took about a 1/4 inch leg to go between and under the key to lift the flat spring into place.
One has to get the tang at the front of the key engaged as well. Certain notes you have to install in sequence as the black keys can block getting a white key in position.

Contact Yamaha America "parts". Be sure to have the serial number of your keybaord handy. Find the phone number online for the California service/support group. They are usually fair in prices of the CD's.
