2019 Z521C. After replacing the right keypad I had no power to bow keypad and left side keypad. Replaced left side keypad it will light up now but doesn’t work. Bow keypad still not working, what next? I lost power and everything shit down at 40mph, had to use plug in key to get back. What next?

Possibly the brain box, under console. Unfortunately, I am not an electrical/wiring expert, and the problem could be a lot of things, including a chafed wire, loose battery terminal, etc. If it were me, I’d be taking it to a reliable dealer.
