Heya. Just got my first subaru impreza. I'm confused about the sigma alarm. If I open the car on the alarm button, I have to start the car within 30 seconds otherwise it immobilises. 
 
	To then get the car to start, I have to press the sigma button twice? It rearms the first time, and then unarms and I'm able to start. This seems rather excessive. Surely there's a simpler way?
 
	I haven't got the code for the key pad, but have managed to change it using a code I found online. 
 
	But even when I put the code in after 30 seconds, it rearms the car then I have to put the code in again in order to unarm so I can start it. 
 
	Am I making a stupid mistake? Please can someone help. 
 
	Aside from that I love the car! 
 
	Cheers, zoe
