200 Montana Electric Door Lock Problem

[Vanrunner]

I recently purchased a 2000 Montana. It did not have a remote for the keyless entry. I purchased two remotes from keyless ride.com programmed them and all was well.

Well being as tight as I am I found two remotes for 25% of the cost I had paid for the others on Ebay. I had a 30 day money on the first two so I sent them back and bought the remotes on Ebay.

I programmed these next two remotes. That is when I immediately started having problems. I would program one and the other remote would stop working and vice versa.

Now, the locks won't work with the door buttons or the remotes. You can hear that it is trying to lock/unlock but it doesn't.

I am sure there is a limit on number of remotes that can be programmed. So if the van had 1 or 2 remotes before I bought it and now I have programmed 4 it could be that I am trying to program 6 remotes.

The second set of remotes have all the same numbers as the first two. The second set of remotes came from two different sources.

Question: Is there a way to UNlearn a remote or reset the system so I can start all over. I think I have really confused the poor little BCM with all of this progamming.

Please help!
