Default Sigma Alarm System Pin Code Change Head Up

Just thought I would let you all in on the information you NEED if you want to change your pin code for your Sigma Alarm system...
....lost my pin and one of my fobs stopped working so, was getting worried that I only have one fob and if that got lost, I would be stuffed!!

So, went to Subaru Dealer and they couldnt find the code on their database or from the factory and said that it was possible for them to change it for me aslong as I had a working fob...cool.....BUT...I will have to pay about £40 for 30mins labour
Cash flow a bit tight at the moment...

Well, after searching and reading lotsa threads from many forums, I found this little nugget.......and it works cos I now have a new pin code..so, heres the golden nugget:

Provided that you can disarm the system with a working Radio Key or the current PIN, then you can re-set the 4-digit PIN to one of your own choosing yourself, using the keypad, at any time.

If you do not have the current PIN, then option A is your best solution. 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

B. Using the current PIN Code (if a working Radio Key is not available):
- Arm and then Disarm the system using the current PIN
- Within 30 seconds of disarming, type into the keypad- **abcd*92*wxyz*wxyz# (where abcd is your current PIN code and wxyz your new PIN code)
- You should now be able to arm and disarm the system using the new PIN code

When using the keypad always observe the following points:
- The PIN number should not be entered too quickly or too slowly - when a digit has been pressed the small LED built into the keypad will illuminate briefly as confirmation and only then should the next digit be entered.
- If an incorrect digit is pressed or the delay between entering digits exceeds10 seconds, then the LED above the keypad will flash rapidly and the PIN attempt should be abborted and started again after 30 seconds.
- Due to the small size of the keypad some users may find a rubber tipped pencil easier to use. DO NOT use the sharp tip of a ball point pen etc, or press excessively hard on the keypad as this will only damage the membrane and cause a digit to remain pressed, causing a continual incorrect PIN.
- The keypad allows only THREE PIN attempts and then will "Lock Up" if an incorrect number is entered a third time. This is a security feature to prevent random PIN attempts disarming the system.

The programming codes just go on and on, so not really suitable to post. What are you wanting to turn on or adjust?


So, it took less than 1 minute to do and now it works....I armed the alarm and then opened the door with the key and set the alarm off then disarmed it with my new pin-code....

So, to save yourself £40 or more, don't keep the original pin-code...change it to something that you will always remember....SORTED!!
