If it's only affecting the a key, and the s key intermittently, it could be something affecting those two keys rather than or as well as the alt/option key. kendog3 could have damaged or affected those keys whilst cleaning.
Did you use any damp or wet cleaning products, kendog3? If you did, you may have made a strange connection by getting those keys wet, and leaving it unplugged overnight might dry it out.
I don't see any reason to doubt him asking for help about this, partly because it seems a bit unfair to suggest that when there seems to be various likely causes for it, and also because I don't know what would be gained by lying about it.
