Hi - I am out at the moment, parked up and went to lock the car (2005 WRX sti) and nothing. Had a spare battery for the fob as assumed that had gone, changed it and still nothing. So currently stranded as can’t turned the immobiliser off to start. I’ve got the keypad thing by the steering wheel but no idea what the code is. Any ideas on how I can get her started? Thanks

 

Can’t make it up, called a taxi with the plan of going home and checking all the paperwork to see if the immobiliser code is written anywhere. Cab comes, as we’re driving away I pressed the key fob one last time…and the lights flash and it locks 😆. Now seems to be absolutely fine. Ah the foibles of 20+ year old cars

 

I used to have problems with mine if I parked in a particular area -- Google told me it could have been caused by nearby 'transmitters' !?!?

 

Maybe it's time to change the PIN to something you know...........................

Info for M30 Sigma alarm
Keypad Use:-
-The keypad allows only THREE PIN attempts and then will "Lock Up" if an incorrect number is entered a third time. This is a secuity feature to prevent random attempts at stealing the vehicle, however, it is also an inconvenience if you are suffering "Radio Lock Out" and enter your PIN incorrectly.
- 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 aborted 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.

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

 

thanks for that, will get the code changed.

 

I’ve since read that too! Had it over ten years and not experienced it before though. Interference would track with the fact it started working as I was driving off in the taxi though as literally walked around the car trying every angle for 20 mins before that 😆

 

Don for president!
So the pin can be reprogrammed without knowing the old pin!?! I never knew that, despite looking through the m30 manual and code sheet. Never found the PIN for my car so will give this a go, too!

 

As long as you have a working radio key, lots of people find out too late..........
