I have a xk8, for the lasy three days when i lock the door with my fob the alarm goes off. It sounds like the doors are locking and unlocking repeatedly then the alarm sounds. Any ideas?

Have you tried pressing the button twice? First time opens the drivers door, second time opens all other doors.

Your key fob needs reprogramming, and yes the alarm will go off when you open the door, but you have enough time to put the key in the ignition which will prevent the alarm sounding. Car is usable until you get the fob sorted by locking and unlocking using the key.

This does not sound like a fob fault - but a locking control module fault , either in the hardware or software of the unit. Get it checked at a Jaguar dealers. When unlocking using the key - as soon as the door is opened you should hear a chime sounding inside the car - this is a timer counting down to sounding the alarm. If you put your key in the ignition as soon as you open the door the alarm should not go off and the chime should stop. If it does not this again points to a fault in the locking controller.
hope this helps - good luck.

Sprawa dotyczy S-Type 3.0 2000r. Pojawi?? mi si?? kolejny k??opot z którym si?? zwracam do Was. T??umacz?? o co chodzi. Od jakiego?? czasu wogóle nie dzia??a mi zamykanie tylnich prawych drzwi, lecz od kilku dni problem sie pog????bi?? gdy?¼ nie wa?¼ne czy zamykam samochód z pilota czy te?¼ z kluczyka ten si?? po chwili samoczynnnie otwiera. Dzi?? doszed??em ?¼e zamykaj??c drzwi od ??rodka ze strony przedniego pasa?¼era zamykaj?? si?? wyszstkie drzwi na sta??e (za wyjatkiem tych prawych tylnich) i w momencie kiedy od srodka otwieram drzwi kierowcy wszystkie sie otwieraj?? po czym za 2 sekundy sie ponownie zamykaj?? i tylko w ten sposób moge zamykac teraz auto i oczywi??cie po ponownym wci??nieciu klawisza zamykania na pilocie uruchamia si?? czówanie alarmu.
Czy Kto?? spotkal si?? ju?¼ z podobnym b??d?? identycznym problemem?? Jesli tak poprosz?? o pomoc w zlokalizowaniu usterki (dodam jeszcz i?¼ w tylnych prawych drzwiach nie mo?¼na ruszy?? klawisza zatrzaskiwania drzwi)
