Never lube primers! I would just about bet you have a Lee auto prime hand primer. If so, just as with most everything Lee discard the literature as it is all poor to terible. The load data is downright dangerous! Get a good manual or 2 if you don't have any. Lyman, Sierra, Hornady, etc. If you already have some, STOP what you are doing until you read them and understand them. Absolutely no manual will tell you to lube primers. Again, never lube primers and YES, put these already fouled cases in your gun, outside, and snap the caps, Resize them and recap them after they've been properly cleaned of contamination.
Oil contamination will at least temporarily kill primers as stated in the link provided by JByer323 although if allowed to dry out on their own for a few days to a few months they will again become functional.
Again, check out that book I linked to in an earlier post. I promise it will help.
