2016~2021 MMS Installation Issue- Step 9 MMS Registration

I did the whole install with no issues. Step 9-3, i get 3 blinks on the LEDs, which states that my fobs are already registered. I cannot verify anything else after that point. I tried to move on to 9-6... cannot perform that step. I have tried multiple times to start over... same result. Moved on to step 10... nothing no horn, no beeps... no vehicle start...

Can anyone shine some light on this with their experience and/or expertise before I spend a month on the phone with Mazda and the dealer?
