My XK8 central lock system - MY 1999 - doesn't want to work any longer. Remote control seems OK as I can hear a kind of relay noise against action on the on/off buttons. Also, flashing light work...
which investigations please ?
Thank you...

Almost certainly dirt on the contacts inside the remote. If you take he remote control apart and thouroughly clean where the rubber keys touch the metal contacts, you should probably find it works.
