Has anyone else had this issue, about a month ago the PCM harness got fried because a bolt the PO put into the EGT bung backed out, and was spitting hot fiah all over the engine bay. I have since fixed the harness, but, since then, when I lock/unlock the car sometimes it beeps and sometimes it doesn't. This is intermittent and rather unimportant, but, sometimes those things really bother me.
My Alarm started doing that about 4 years ago, about 6 months after I bought the car new. It started by intermittently beeping, and after about 6 months of sometimes beeping and sometime not, it stopped entirely, and hasn't beeped since. Also, my lights no longer flash, but the dome light inside the car comes on when I unlock, and goes off when I lock. At the time, I saw a thread on Nasioc with people reporting the same issue. I think at the time, there were about 200 people signed as having the same issue, but Subaru has never done anything about it.
