Have a friend with an 03 Legacy L wagon. The car did not have a key fob when he bought it and his girlfriend asked me to help her get him one for his birthday. His car should have it from the factory, correct? Should just have to program and go?

I don't know if it's factory or not but it's usually pretty easy to spot the dealer-installed keyless entry controllers under the dash. They have a couple inline fuses, and a label on the box that indicates their function.

Yes, definitely should have everything needed installed from the factory. Just program and go. I'm not sure if you can use the remotes with the grey buttons that came on the '00 models. But the Orange and Blue button remotes will definitely work.

 

Same thing happened to my '02 OBW when i picked it up.. no fobs. There is an Alarm upgrade available as an option which will make a light on the cluster flash.

 

Programming the remotes is a bit... awkward... at best. There are a few good write-ups on this site though.

you'll have to get the blue/orange button jobs.

i have some brand new Subaru remotes for this application if you're interested let me know.

Cars101 shows the new teardrop style has now replaced the older fob style.
