If your keypad is connected to your control board by a flat ribbon wire, try disconnecting it and clean the silver contacts with an ordinary pencil eraser. After cleaning, plug it back in and try it. If it doesn't fix it, replace the keypad unit. Some units actually have keypad tests to confirm your diagnosis of a bad key.If your keypad and control is the same unit, replace that unit. Another note, unlike stove/oven keypads and controls, most microwaves do not have error codes or tests to distinguish whether it is truely the keypad or control.

Since the timer works it means that the defect is in the magnetron or its power source. They can be replaced, but only by a repairman: because of the extremely high tension (over 5,000 volts) specially insulated tools must be used. A new magnetron will cost around $125, the labor to install it another $100. If you can buy a new oven for less than $400 then it's time to junk this one, it's not cost effective to put so much money to fix a really used one.
