I have looked all over and found photos, and part numbers for the remote entry, and security module. I am certain that my car had these to begin with, as there is a logo about factory security. I don't have a keyless entry remote provided with the car when I bought it, and there is a horn under the hood (which has had wires cut to it) I already bought a new remote (hoping that it would just program, and go) Now I don't want to buy anything I don't need, but the symptoms are this: I can only lock/unlock driver door with key, or the tab next to inside door handle. The buttons on driver or pass. side un/lock all 3 other doors though. I am wondering if this sounds like someone has made changes on purpose, or if this car was a victim of a crime sometime way back? I saw the mention that a security module would be found under the armrest, so I will look there in the morning. Any help or guidance would be sweet.
