Does anyone know if you can use the cool new integrated keys that come with the 2008 Legacy's on a 2007?

Probably not....I'd try asking the subaru dealership.

I have, they simply said they didn't know and if I called Subaru of America they would only say that they wouldn't recommend it because they were not the same part number as the '07 keys.

I haven't seen the 08 keys, so I'm not sure if the difference is just appearance or not. When you say they're integrated, what do you mean?

Not sure if they would work or not. Joe has a ton of Subaru key info at http://www.cars101.com/subaru/keyless.html

Does have pics of the '08 and earlier keys and remotes, doesn't specifically say if '08 key will work on '07.

Good info there on programming the remotes too.

Yes there's lots of good content on cars101.com The site comes up #6 in a google search for 'Subaru' and has a good PageRank, so must be doing something right!

They Keyfob is integrated into the key itself

The main thing to look at is the width, length, and grooves in the two keys. If that part is the same you can get the key section to work anyhow.
