RPO Code AU0 (AUzero) is for remote locks. AU3 is for an electric door locks. If you have AU0, then you will have AU3, but having AU3 doesn't mean that you should have AU0.

 

Rats.

I’ve got AU3, so it never had the keyless entry. Given it was loaded with so many other options, I was hoping the fob had just not gotten transferred. Oh well.

Thanks to the both of you for the heads up.
