Hi everyone hope someone can advise me recently purchased an 2004 wrx and it didnt come with its pin code how can you get it resest is it a dealer only job? My key is currently working fine but would like to get the code more for peace of mind than any thing
thanks steve

 

I was in exactly the same predicament last week, I've copied this from the sigma alarm pages (can't find link)

Resetting PIN code:
*
If you do not have the current PIN, then follow option A. However if you do not have a working Radio Key, then you will have to use option B and obtain the systems PIN code from Subaru (UK). Your dealer can obtain this for you if you can provide proof of ownership and the alarm systems 16-digit serial number.

A.Using a working Radio Key:
- Arm and then Disarm the system using a working Radio Key.
- Within 30 seconds of disarming, type into the keypad- *17856*92*wxyz*wxyz# (where wxyz is your new PIN code)
- Arm the system with the Radio Key
- You should now be able to disarm the system using the new PIN code
