A new battery is not a "cure all" for automotive problems.

A battery is simply an electrical storage device that provides electrical energy for the NEXT time you need to start the engine.

But to start the engine everything has to work in coordination:

The engine must have adequate compression

There must be a strong spark, timed properly to the position of the crankshaft

There must be the proper amount of fuel delivered to the cylinders as the engine crankshaft is turned by the starter motor.

The starter motor must be capable of turning the motor at an adequate speed to build the necessary compression.

If the starter is not engaging, you need to find out why, is it the starter? keyswitch? neutral safety switch? wiring???

If you don't have compression... why? Is it a valve problem? camshaft timing? damaged/worn pistons???

If you don't have fuel why? is it a fuel pump problem? fuel pressure regulator? injector activation?

if you don't have adequate spark... why? is it the coil? a sensor? distributor???

There are plenty of questions that have to be asked before you blame the battery, and you need to understand what's wrong before you can repair it. Never "throw parts" at a problem in hopes that you'll eventually find out what happened.

How do you get out of park when have a flat battery - automatic?

If your battery is dead then you are going nowhere therefore why would you need to take the car out of park? Get a jump start from another car with a good battery and then you can start your car and drive to the nearest battery dealer and buy a new battery if need be. Otherwise just put a battery charger on your battery and let it fully charge.
