security sounder(alarm)

[mrpopey]

Do the security sounders on the x type fail often or are they reliable ?

What are the symptoms of a failing or failed security sounder ? and would a failing/failed security sounder lock the starter/ pats system and prevent starting of the engine ?

Have an ongoing pats problem here and getting nowhere with it at the moment and need some help asap and as the car isnt starting then taking it to the nearest jag specialist is a no go and the nearest one dont do mobile

HELP ! ! !
