Hi guys long time off here but need your help.
Have had alarm problem on my 05REg 2004 wrx, faults as listed below.

First annoying thing was false alarm going off (only backup siren)
With help from previous thread changed 9v battery.

Was OK for few months but now suddenly,
No LED visual when armed
No red LED on key pad and no response to pin code.
NO siren sound.
Central locking works etc. and ignition cut out and if alarm activated the indicators flash.

Having worked in the trade for over 27 years and know what I am doing
I have traced the unit and I believe it to be the main control box.

Hence my request for your help.
Contacted main Sigma web site and no luck.
Does anybody know where (not flee bay) I can purchase a new unit without the hassle of going to an authorised dealer.
Thanks again.
