Been searching for ages for help with a Sigma Alarm and this site keeps popping up so hope someone can help.

I recently changed the car battery and now the alarm goes off every time i open the doors. The cars second hand and i dont have the alarm code to enter into the key pad. The Sigma instruction booklet had the alarm model as either an M12 or M30 I think.

 

Suspect that this is an M12 alarm and that you are using the vehicle's existing remotes to both unlock the car and disarm the alarm - non Subaru.
Disconnect the battery again, reconnect and then operate the vehicle's remote to Lock, Unlock, Lock and then Unlock. The M12 alarm system will then re-learn the arm and disarm inputs.

 

appreciate the help, will give it a go


tried it but stil no luck, alarm still goes off
