Any idea as to how to program a remote keyfob on 1991 XJ6 Van Den Plus? I couldn't find any instructions googling. THe open door/hold headlight switch doesn't work. There must be another way for older model like mine. Any help would be appreciated.

 

I have NO IDEA, but I would strongly suggest reposting this in the XJ40 area, as that is what your year model is known as.

One of the lurking moderators may spot this, but maybe not, so the ball is in your court.

The XJ6 cars in this area did not have remote fobs etc.
