Check the three terminal block on the right front wheel well under the hood. There is connections there for the starter and the power for the car comes from there. Check that the terminals are clean. You can also activate the starter from there. Jump from the heavy wire to the smaller one. The starter should engage. This will tell you if the starter is good or not. If the starter works from there but not at the key, Either the neutral safety switch or the key switch failed. You might need a "Hard Start" relay.
