They will not just give you the master code over the phone, or anything like that, as they do everything possible to avoid general public knowing the Brant master code. Unfortunately you will need to get the car to a Subaru dealer for them to input the code for you.

I gave RMS (so S-Technic may have it now) my old Brant control module which I had the master code & PIN's changed from Subaru's ones..if they do still have it you can put it into your car so you'll at least be able to drive, rather than pay for towing, to Subaru. Put yours back in, get them to input their master code into yours and return the other one back to S-Technic.

It'd be worth giving the reset thing a try first, although it never worked on my Brant, you might get lucky.
