Hey,
Dont own a subaru but this is the only place I can find with a section on security.
I purchased a new car yesterday ( second hand) and it comes with a sigma alarm. The fob has a grey button and three little l.e.d lights on the end.

The owner was very brief in describing the instruction on how to use this and i find the alarm goes off sometimes when Ive armed the car, ( or thought Ive had)

Could you tell me the instructions on how to use it, and should I have a keypad in the car?

Thanks alot.
Felix
