No need to pay Subaru dealer or anyone to resolve this on the m30 alarm.
As long as you have a working remote you can input a new pin code even if current pin is not known.
Have done a few of these for customers & normally for free.
Instructions are below, please follow correctly & make sure you input digits on the keypad so you see red led flash one time for each press, if you are too slow you will see the red led flash multiple times & will need restart from scratch.
Once done correctly the alarm will chirp to confirm process complete, test you chosen 4 pin code for arming & disarming of the alarm then have a cup of tea, make a secure note of your current new PIN & say thanks ...
Enter new PIN on M30 alarm (1 working alarm fob needed)
- 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
Notes on using keypad:
- 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.
