SOLVED - Immobiliser Issue (I think)
 

Hi all

I was doing some work on my 02 Bug Eye WRX earlier, which necessitated unplugging the battery and ECU.
I've plugged it all back in, but the car won't start.

Both keys will lock and unlock the car. However, the car won't start.
Also, with the key turned all the way on, when pressing the button on the key, the car will lock, instead of turning off the immobiliser.

Any ideas on how I can reset this?

Thanks

sounds daft, were you pressing the clutch when trying to start it ?
Sounds daft, but a member on here did it.

I'm sorry, I don't understand.
What does the pressing the clutch have to with it?
It's not in gear, if that's what you mean. The engine will turn over but not fire.

The light around the ignition barrel is green if that helps.

Some require the clutch peddle to be depressed to start . . .

Nope, tried again to be sure, but have done that before.

The main thing that's odd is that the immobiliser doesn't recognise the ignition is on. Instead of just turning off the immobiliser, it turns on the alarm.
I'm sure that's the key (see what I did there) problem here.

BTW, I can't use the keypad as it's been damaged before.

There are two immobiliser devices.
One in the sigma alarm and one OEM one that utilises a transponder chip in the key.
If the keypad for the alarm is damaged why not purchase a new one?

I didn't know that. As I've removed the battery and ECU, I would expect the problem to lie there.
Is there a reset/reboot option?

I will, now that I know it exists. I didn't until this problem occurred earlier today.

Because it really winds me up when I find threads with the same problem I have, but no solution, I'm adding the fix here.

Check the IGN fuse in the interior fuse box, mine had blown*.

Something so simple.

*Technically we blew it when prodding wiring....

Great result.

Hi all, I am new on here this may have already been done time and time again. have issue with sigma alarm it has a number keypad in glove box don't have the code for it. lost when in garage last time. had the battery out of the car for a while and yes as you
guess will not start. any ideas how to fix this. Its driving me nutz :)

Welcome to Scoobynet but really should start a new thread for things.
This should help but need a working fob.

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

Instructions on doing this can be found in the security systems Operating Instructions. If you do not have these, a link to a copy can be found in the post at::

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.

Hope this helps.

Many thanks will give this ago you are a star :)
