Power Locks - 1996 T&C

I have seen a good number of posts in the newsgroup regarding problems with power locks, but not a lot of solutions.

Maybe I can ask the group about the problem with my locks.

1. The electric locks work perfect from all inside lock switches.
2. The "un lock all the locks feature" works perfect from the tail gate lock
3. From either driver or passenger door when the key is turn to unlock the door, the locks usually unlock and then re-lock immediattly.
4. The keyless fob does nothing - I am not sure it is the right one. It has not worked since I bought the van.

1. Battery is new (there were some references to low batteries).

So, is this a solvable problem? Can I disable the power locks and revert to manual locks?

Thanks
