Try cleaning one or both of your keyboards...
Yeah, it takes a while, disassembly, popping every key off, alcoholing each key to remove sticky junk, popping them back in, then wiping down the "plastic circuitry" with an alcohol-based wipe, then reassembling the whole mess...
However, for the hour's or so work on this (shorter if I get my oldest to help pop and replace the keys), I've restored many a spill devastated or just plain dirty keyboard to full functionality for a couple of months, letting me stash some cash to buy a new keyboard...
