Without doubt one of the worst things to do with any keyboard is to use WD40 on it. It is intended to be used on motor vehicles, around the ignition for instance. You can do untold damage with WD40 – we see this with clocks regularly and when one comes in for repair we double the service charge.
Recently I had a church organ to repair where the transpose keys and the preset tone keys had jammed up all due to the use of WD40 in the past.
So having said this, what should you use? The answer is simple use something designed to be used on electronic equipment, Electrolube, also known as contact cleaner. I don’t know what the name is in the USA but I’m sure you have similar products.

I see this problem with a lot of Hammonds and I usually try to cure it without taking anything apart,the grease on the mechanism gets thick with age and keeps the bars under the keys from moving,the way I fix it is by squirting WD-40 beside the keys and pushing them up and down,use the little hose that comes with the WD-40 so you can shoot it all around the keys,the sticking mechanism is in the frontal part of the key,the WD-40 mixes with the grease and loosens it up,once you get the lock down bar to move go back and forth between the cancel key and the various preset keys,the volume should also return by rapidly moving the keys up and down because it usually is caused by dirty key contacts and the movement will clean the contacts,I've been fixing Hammonds this way for 30 years.only after trying this do I rarely have to get under the keys,if you have to get under them it is a bit of a project but only takes about an hour.
