Programming Remote for 99 Forester

[Mike]

Hi,

I got a new remote for my 99 Forester and tried to add it. It worked
fine but my other remote stopped working. I tried to add the one that
was not working several times and couldn't get it to work. Now the
remote that was working is not and the programming button under the
dash doesn't respond at all. It seems like something needs to be reset
before I can program both remotes again. Does anybody know what I
should do next?

Thanks,
Mike
