Sigma alarm 2011 sti
 

Hi I'm in need of some help I have a 2011 sti i believe the sigma to be a m32 from what ive read but not sure,the key fob work ok new battery,but noticed the alarm does not activate. No led warning by clock display.
But if I use the key pad with said code I can activate the alarm and the led starts off green then flashed red as per manual. When set if I wave hands in front of the interior sensor led goes static red like detects but does not sound alarm.if I open door alarm sounds.
I can use the pad to arm and disarm alarm, but does not work when locked with the key fob..thanks in advance
