hi could anyone shead some light and educate me a litle about these subaru alarms.my subaru is a 2001 blobeye it has the keypad by steering column etc.i have 2 keys and a sigma fob.,trouble is my alarm goes goes off now and then and i cant disable it.im getting work done on it and had to have battery disconnected and the alarm siren went off as it should but i cant stop the alarm.how do i disable without codes .i dont have any pass code off previous owner and im stumped .also my 2 keys have the open and close buttons but no batteries inside them and it uses the little blue and black fob to open and close car..help need asap .thanks.

 

The sigma fob should disarm the alarm ?

 

thats what i thought ,but when i undo positve lead of battery the siren goes off ,how do i disable the alarm noise .thanks

 

its running on battery back up
as long as the alarm is disarmed then it should be ok

 

i had the excact same problem with mine. Apparently when they are imported to the uk they have a 2 button key then they are fitted with the sigma unit and the key front is swapped by subaru uk to a single button. I bought a new sigma unit and it came with the little blue fob and also came with instructions to program any key to it so i programd a single button key to it. Pretty easy. I then found out later that alyn at as performance knows how to sort them without buyin another alarm unit

 

thanks ,but how do i switch it off on the keypad ,i dont have code to type in.can i make a new pass code as i have to keys still.

 

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
