[Apologies - one last "Google" and I found the answer - all three will need to be re-paired]https://www.autoreservejaguar.com/news/remote-fob-programming-intructions-for-xk8-xkr-1996-2006/
I have two existing fobs and separate keys.
I plan to add new fob with an integrated key, as per the instructions elsewhere on the site.
When I pair the new fob, do I need to re-pair the other fobs or will they still be linked after the pairing procedure?
Thanks in advance

 

Answered your own question.

YES - all fobs MUST be programmed together. You can't add one separately.

I've added RESOLVED to your thread title.

Graham, frustratingly for me, I've gone off at half **** and I've discovered that the flip key winging its way to me from eBay is very unlikely to work with and replace my MY2000 XK remote to allow cannibalization of one of my keys..... Ah the virtues of patience that I lack....

 

I'd be very cautious about taking a large hammer and a pair of pliers to a fully functioning remote/key too!
