Thanks Ronda.
By repair process I mean taking the keyboard completely apart and removing the smelly adhesive. From what I've read, it seems that hazardous solvents would probably have to be used, and in a well ventilated area. I can't quite recall where I read this, but the excellent page I started at, which has a lot of links on the subject is:

I must add that there are several sites which recommend disguising the oder with air fresheners. I think this is a bad idea because the gas being emitted by the adhesive may very well be toxic. It may not be, but who really knows? It's best to replace the keyboard and not take the chance.
My smelly keyboard has a green ribbon cable. I'm waiting for one with a clear ribbon cable to arrive in the mail. The seller said it doesn't have an oder. I'm guessing that perhaps the keyboards with the green cables had the problem, and the ones with the clear cables didn't? It's a possibility. Anyway, I've wrapped my current keyboard in anti-static plastic, and that has cut the smell down quite a bit.
