Confirmed battery is not dead, key will turn, not start, why.

What is your question?

Was in a bit of a hurry, put in key, tried to start car by turning it too quckly, acted as though it was going to start, but did not. Tried again and the brake pedal would no longer engage locking up the stearing wheel, so the key would no longer turn. The lights and blinkers work, car will not start. Confirmed battery is good from place of purchase.
