Well, I've searched around on various subaru forums about this issue, and seen some similar problems but no real solutions. So, I'm hoping someone here can help me out.
I have a 97' Outback with two remotes for a keyless entry system (OEM system I'm pretty certain). I bought the car used and it only had one remote so I bought the second on Ebay back then (in 2002). I believe I put new batteries in at that time, but I'm not sure. Over the past 2 months, BOTH remotes have slowly been declining in their effectiveness to the point that now neither of them will work.
Naturally I assumed it was a battery issue and that both remotes' batteries decided to die around the same time (sort of unlikely, but not impossible). So, we finally got some new batteries for them, but they're BOTH still not working. So, I got the silly idea that maybe they needed reprogramming with the base unit (I now know how the system works and that this was unecessary, but I did discover something in the process). As I was reprogramming, the remotes did actually communicate with the base unit as it asigned their codes to the system. However, I discovered that I pretty much HAD to have the remotes no more than 2 inches away from the antenna that sticks out of the keyless entry harness. So, as long as they're within 2 inches of that antenna, they work great! Of course, I still can't operate it when the doors are closed...
So, does anyone one know what the issue could be? I opened up the remotes and cleaned the contacts with alcohol and even tried cleaning up the system board itself (one was pretty nasty, the other clean as a whistle) - all to no avail. It would seem that the remotes aren't sending out a strong enough signal, but why would BOTH remotes have been stricken at the same time? Is there something that could be wrong with the base harness itself where it's needing a stronger signal for some reason? Obviously its working to some degree since I can reprogram it and it will respond to 2-inch-away *remote* commands.
Anyway, I really don't think buying a new remote will help my situation, so I'm looking for what the solution could be. Thanks for any guidance/help you can lend.
