Morning, sounds like we have no voltage at all. Can you remove both terminals, clean them, soak them in a cup with baking soda mixed on water then rub them together to drain capacitors then hook back up
Capicitors are electronic components inside the computers on your car they store voltage even when disconnected from battery, your comput err uses this to store memory for different functions, this sometimes causes a module to go into what is called "logic lock" and it could cease to function or function improperly. The only way to drain this energy and force your modules to reboot is to take the positive cable tie it to the negative cable for a few minutes then hook both back up to battery
If your battery is new and test good but you still have no power, and you have double checked connection. Lets break out the voltmeter you ready
