New owner of a 2006 SANTE. Previous owner never set primary user code. He was the second owner. I have the master embedded code from the dealer and am now trying to set a primary user code in order to lock the boat. I have the user manual and am following the instructions but I'm not having luck. When I hold the 1/2 - 7/8 key the system indicator light will flash, but only briefly and it won't allow me to set a code. Suggestions? Thanks!
