Great guide and handy - Reprogrammed my key fob that died without needing the pin code. Then reprogrammed the pincode to what Subaru had on record (didn't work before!).
However now the alarm goes off 2/3 of the time when locking or unlocking? Only since I changed the pin code and reprogrammed keys. Any suggestions? The only way round the problem is keep pressing the remote lock until it's unlocked and alarm isn't going off!
Thanks
