My 2007 XJ8 VDP key fob had worn out internal activation rubber key pads, along with two bad contact points and it was only occasionally functional. I purchased an Ebay duplicate for $15. It is identical to the original except, the push to release key knob facia , doesn't have the Jaguar impression. I removed the section containing the original bayonet key & facia and slipped it on the new key module, as it fit perfectly.. Now I have to find a way to get it programmed to my car in order for it to be useful. I won't have to have the provided blank bayonet key reshaped since I am using my original working bayonet key. Any advice on how or where to have it programmed, other than an expensive Jaguar dealer, that I have heard charges$100+?

 

I recently replaced the case for my 2008 XJ8. I simply moved the electronics and glass capsule to the new fob and it worked fine with no reprogramming needed.
Cheers!
