Ok, this is a much better explination of the problem. I have an aftermarket alarm/keyless entry system instllaed on my 1996 SE. (i had this problem before it was installed though)
I can use the remote to unlock ALL doors succefully.
However i can only use it to LOCK all the doors except for the drivers door.
The only way to lock all the doors with one move is to hit the plastic lock lever on the drivers door. This will lock all the doors.

Does anyone know what this problem might be? I am thinking it may be a broken wire or something like that. Can anyone help me with this?
thank you
