subaru impreza wrx s series ac111 sigma alarm?
 

Hi all ,
im alittle new to the subaru world, but have since bought one and love it ...but im having trouble with the alarm the battery on the car went dead a couple of days after i bought it so i charged it and put the battery back on but now when i go to lock the car it does nothing ??

dosent even attempt to lock but it arms the car because if i open the door the alarm goes off??? and if i try to lock it with the key in the drivers door it sort of fights back and wants to stay open ???????

does anyone have any idea what this could be??

Thanks for any help of replies i appreciate it thx

Battery....
get a volt meter on it and see what it's putting out.
I'm having the same issues with my RB5 ATM it's doing my nut in!!!

ive read it could be ....

a dodgy door/bonnet/boot switch ...or...

inside drivers door it could be a solinoid so anoying i have to dis-connect my battery to lock the door ...!
