I have a 99 OB wagon with the subaru security system. The keyless entry works as does the panick button, but I cannot get the alarm to sound. I have even armed the car while inside and then opened the door and still no alarm. Any clues?

I think you're in valet mode. http://www.cars101.com has all the info about how to work the thing.

 

My '00obw has the code alarm; not sure if that's what you have, but on that one to get in/out of valet mode, you close all the doors, then open the drivers door, then hold unlock for about three seconds.

double check to make sure the wire going to the siren / horn (passenger side strut tower?) hasn't been cut.

It was in valet mode. Thanks!!!!!
