Provided that you can disarm the system with a working Radio Key or the current PIN, then you can program new Radio Keys into the alarm system yourself, using the keypad, at any time.

If you do not have the current PIN, then option A is your best solution. However if you do not have a working Radio Key, then you will have to use option B and obtain the systems PIN code from Subaru (UK). Your dealer can obtain this for you if you can provide proof of ownership and the alarm systems 16-digit serial number.

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*91*n# (where n is the total number of keys required to work the system)
- Press each Radio Key briefly in turn (the dash board LED will flash and the siren beep each time)
- Once the nth Radio Key has been programmed, you should be able to arm/disarm the system using any of the Radio Keys programmed.

It is essential that all Radio Keys required to operate the system are programmed together. Any keys not present during the programming sequence above will no longer operate the system.

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*91*n# (where abcd is the system’s PIN code and n is the total number of keys required to work the system)
- Press each Radio Key briefly in turn (the dash board LED will flash and the siren beep each time)
- Once the nth Radio Key has been programmed, you should be able to arm/disarm the system using any of the Radio Keys programmed.

It is essential that all Radio Keys required to operate the system are programmed together. Any keys not present during the programming sequence above will no longer operate the system.

Instructions on doing this can also 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.
 

Hi there 

This is a brilliant guide , however I'm a bit stuck as I neither have a working radio key and also my immobiliser PIN has been changed in the past .. is there a way to reset the PIN and then use it to reprogramme my 2 keys ? 

Many thanks 

Mot sure can with no working code or pin mate. I'd be surprised if there isn't away but I don't know it.

I'll have a look in my files .ca t remember if a bloke I know sent a hack guide I know he was on about one. To me but not sure if he sent it.

Had a look it's pretty much same stuff I've posted on here just goes in a bit more about the frequency of transmitters and interference that sometimes blocks the signals. So at this point in unsure what the best option is without having to get a dealer to sort it [emoji53]

Go to a sigma installer and the will do it via cable and software.

Option 2 is if still got a remote but it not working is send it away to repair service like see on ebay and if get it back fixed then use the opportunity enter new pin with working remote .

Hi!

Should that instruction work on a 2009 Subaru Impreza UK model? I think I have the M30 Sigma alarm. After putting the 17856 code I can hear a beep and also I can hear it after putting the # character, but when pressing the fobs it is not working as expected. I want to program 2 fobs, one that is working and another that I bought recently. The working fob when pressed, arms the alarm, pressing the non-working fob does nothing. So something is not right.

Here is the story. I bought the car with only one key. I went to the dealer but they want £360 + programming (and maybe + vat, not sure), so that's not an option for me. I bought a used key fob just to be able to open the car remotely in case the key I have now stops working, but so far I can't find a way to program it.

Any help appreciated.

Thanks.

 

Sorry for double posting, but I don't see how to edit my post.

Just wanted to add that I am also not sure if setting a new pin using the fob works for me. It beeps once after the programming code (17856) and then it beeps once after the rest of the sequence (*92*CODE*CODE#), but then I am not able to use that new pin code, neither for arming nor fob programming with option B.
