I know this has been asked a zillion times before and I have ploughed through some posts to try and find the answer - but to no avail.

I have a sigma alarm and it needs resetting to tally the fob with the unit. We are members of SIDC and I was previously given this by SigmaSam - however, I can't get onto SIDC because I can't remember my username OR password

Does anyone know the *# sequence????

 

Hope this info helps, I found it on another post about the Sigma alarms:

Changing your PIN:
- 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

Ensure your keypad is operational before you need it on a dark night!
If this is an intermitent problem, use of the keypad should overcome the problem. However, if the problem is more frequent it may be worth considering a new control unit - An SACC 3465 should cost in the region of £70 from a Subaru dealer and your existing keys can still be used.
Although installation may take around 30 minutes, do not pay over the odds for programming the system, as this can be done in 5 minutes using the keypad.

Otherwise, you'll probably need to take the car to a Subaru main dealer and they will be able to do it.
