I can not turn the ignition key

The steering wheel will not lock into a position so that the key will turn. the gear shift is in park, and we made sure we pressed the brake. Any ideas? Thank You

If someone turned the engine off while holding the steering wheel 'turned' - it might be necessary to turn the wheel a little to 'unload' the locking mechanism between the steering shaft and the ignition key. For instance, If the wheels were turned to the right as the engine was stopped - it would mean turning the wheel to the right a couple of degrees more.
