Why wont the key turn all the to start with foot on brake in park.

Sounds like you might have a worn lock cylinder.

You can try some "lock Ease", or powdered graphite in the lock cylinder, but you likely have a broken tumbler inside the lock. Those are the brass pins that fall into the grooves on the key. The key code for your ignition key is inside the passenger door on the lock mechanism. The inner door panel needs to be removed, and the door lock needs to be partly removed to see the code numbers on the door lock cylinder You can then order a matching keyed cylinder. The less expensive way is to just purchase a new aftermarket lock cylinder that will come with a different key that won't fit your doors. To remove the ignition lock cylinder, remove cover panel under steering wheel. Insert key into ignition, turn key to acc, push button on bottom of cylinder under the dash, and pull the cylinder out of the dash. Install in reverse order.
