Alarm Failure on 2002 Jaguar XKR

The Alarm system continues to fail and prevents the car from starting. Dealer was visited twice; module in ignition switch was replaced. Same problem continued. Now, alarm will beep, but won't set, but the car will run. Idea?

Yes, it should run,
My problem is before I brought to Dealer, the Alarm didn't work
but car was fine, now after they charged Alarm reprograming then
now doesn't work they said it's Modual problem.

It's better off not bring it to dealer , I bet your car is over 5 yrs right?
