- - Key Fob (https://www.jaguarforums.com/forum/xj-xj12-x305-57/key-fob-212683/)

Hi, I have a 2003 jaguar xj sport and it has the single key fob. I was looking on ebay and certain sites and I have seen the all in one flip key fob, my question is would that type of fob work with this model vehicle if I take it to the dealership to get programmed ?

You shouldn't have to go to a dealer to program a new key fob for an older Jag. It is an easy do-it-yourself procedure. But the fob must be of the correct frequency. The new universal fob should have some information on what vehicles (or frequencies) it can be used for. The 2003 XJ8 is likely a 433MHz system. You can confirm this and find the procedure in the XJ8 X308 forum section.

I'm not so sure a dealer would be willing to try to program an aftermarket universal fob for you. But they may be able to sell you an expensive original!

For a 2003 XJ8 X308 it has this listed and maybe applies to yours
