hey van and welcome to the club
there is only one button on your key head ,right ?
the button locks the doors and unlocks them, right?
but when you hit the car it doesn't go off,right ?
well the alarm works
it just does not have a shock sensor
it monitors all the locks for the hood trunk and doors
just turn the key off one day
sit in the car
and arm it
then try and unlock a door after 1 minute
it will go off
the light on the dash flashes, right?
