I’m not sure what the problem is since neither one of the keys will work in the door nor the ignition. That doesn’t add up at all.
Does the ignition switch even rotate to the start position using these keys? Key turn ignition switch ok? Is it possible you have the keys to another Ford vehicle - that also lives there - instead of the Mountaineer keys?
