Yes, take it apart, and wash the circuit board.
Hard part is taking it apart without breaking the little tabs that snap the case together. It may have a couple hidden screws somewhere like in the batt compartment or under a label or under the rubber feet. Then carefully pry the case joint apart to get the snaps to let loose. Then the circuit board easily comes out - be careful if all the keys are loose not to disturb them. Also be careful of the display that may be loosely mounted. Once you get the board out, you can wash it with soap and water - whatever, just rinse it when clean with something like alcohol so no residues are left. Also be careful to not rub off any off the black key contact spots where the keys touch it. Put it back together loosely and see if it works.
Hope Ya Fix It!

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

It could be some dirt or grit in the keyboard, which a blast or two of compressed air might clear out. It could be a worn dome on the inside of the keyboard.
If you want to have it repaired, there's FixThatCalc, though they're currently not taking new orders. There also have been several threads on opening and cleaning Voyager series keyboards at the Museum of HP Calculators. Here's one article on opening a Voyager.
