Outback 2.0XT, Audi TTq, Ducati M750
Maybe a silly comment, but the key in the pic is too far away from the ring compared to when its totally inserted in the ignition, could that be it? Maybe also dumb, but could you install all the parts into the car and try to go through the key-programming sequence separately? I assume you've given those ideas some thought, just some quick input. Overall this is amazing stuff, I've been side-glancing swapping to an automatic WRX gauge cluster for the center tach, I assume programming would be cake but don't know if it would physically fit; that's another thread though.
