One saving grace is that the dealership does not need to access to the BCM in order to do the reprogramming, so I was able to put all my trim back after installation. They did however say you can hot swap the part yourself and come in later to reprogram it, BUT, you may risk losing features like rain sensing wipers and power locks. Both service reps assured me the "BCM will need to be reprogrammed in order to ensure proper function". I called two different Mazda dealerships to check if the part needs to be reprogrammed.

I am fortunate enough to have a good friend who is a mechanic and I was able to use his shops OBDII scanner to verify the error was within the BCM. I purchased my Mazda 3 used and when I did, the seller actually informed me the last time they went to the dealership there were error codes associated with the BCM. I after doing some research, I found that a handful of other Mazda owners had similar problems and remedy it by replacing the BCM. Even more confusing if I manually locked all the doors, then stepped outside and pressed lock on the fob, lights would flash, horn would beep, and the car was locked. The fob could unlock the doors, but not lock them. When using my key fob the doors would not lock when outside the car. Original Problem: My power locks were broken.
