Key Question
 

Sorry if this is a dumb question but one of my keys is not working. I have a 2005 Impreza WRX and the electronic key is not opening the car. I've replaced the battery and followed several sets of instructions online showing how to get it working again but nothing seems to work.

Does anyone know how to fix it?

Assuming it's still the OEM Sigma alarm fitted.
Do you know the PIN for the alarm keypad??
Always handy when a key stops working, but as you still have one working you should be able "re-pair" the keys to the alarm and reset a new pin.If this is the case then you will need to follow the procedure below with both keys:
- Arm and then Disarm the system using the working Radio Key.
- Within 30 seconds of disarming, type into the keypad- *17856*91*2# where 2 is total number of radio keys to work the system
- Briefly press both radio keys in turn (the dash board LED will flash each time and the siren will bleep) Any radio keys not programmed here will no-longer operate the system.
- You should now be able to arm and disarm the system using all the radio keys programmed.

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.

If the spare key still doesn't work then there are 3 possible reasons:1. The key battery is flat (the built in LED takes very little current to illuminate it and is not an indication that the battery voltage is healthy).

2. The key is damaged or faulty.


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.

Wow, thanks for the reply. That's really comprehensive. :)

Op, you’re relatively new, so I guess you haven’t had a query answered by Don Clark before.

So, yes, he really is that good.

Happy New Year.

Thanks, I'll be sure to seek him out and pester him with endless questions again in the future :D

Yes, but please don’t get carried away.
I think that even Don might struggle with the real ‘key question’...

... why does the universe exist? ;)
