You can also create your own high-humidity event by spilling a drink in your keyboard.

One solution is to - very gently - use key-easing pliers to compress the wood around the key bushing. If the Wurlitzer’s environment is too humid, the wood can swell so much that the key can’t move freely along its key post. This can happen if the seasons change, or if you move the keyboard to a different, more damp, room. Has anything about the keyboard’s environment changed? Wurlitzer keys are made from wood, so they’re susceptible to excess humidity. Ensure that all of the screws in the mechanical action are appropriately screwed down, paying close attention to the screw holding the hammer in place of the key in question. Have you recently moved the keyboard? If your Wurlitzer was recently shipped, or even if you just transported it across town, it’s possible that a screw came loose while it was in transit. If your Wurlitzer’s sticky keys are a new development: Was the Wurlitzer previously working fine? There’s a difference between sticky keys in a Wurlitzer that has recently worked, and sticky keys in a Wurlitzer that you just dragged out of a basement.
