My key works on and off now for a couple of mo.s ... replaced battery but it does the same thing ..any one else have this prob,

Keep this in mind...a 'new' battery could also be defective.

If you have another key fob, give that a try. If you do not have another, it might be time to see about obtaining one. Always good to have a back up.

When I bought this car years ago, I got two keys. One quit working with the remote, the other works fine. As is my habit, I took it all apart and cleaned it and put in a new battery. It still doesn't work and I even tried the battery in the working key. Still doesn't work.

It sounds like you have done about all you can to confirm that the one key fob is kaput, VB. If it were my unit, I would make absolutely sure that the switch contact is making and I probably would use a spectrum analyzer to look for RF energy (thats not an option for many).

Probably time to buy another key fob while you still have one working unit.

Yup, in a perfect world I would do all that. Haven't fooled with it in a few years. I'm just really careful not to lose the working key. I'll have to look around and see if I have a spectrum analyzer, might have one at work.
