We agree with the insurer. All of the keys to a covered auto are definitely auto equipment that is covered if they are lost or damaged. But, in this instance, the insured lost only the one set of keys and that should be paid for by the policy. As for the other set(s), they were not lost or damaged. If the insured wants to change the locks and make the keys unusable, that is not an accidental loss; the insured is choosing to make the keys unusable. We can understand the reasoning behind this, that is, to prevent a possible future theft. And, the insurer might want to consider this since paying for a new set of keys is a lot cheaper than paying for a car that has been stolen. But, as of now, the insurer is right: there has been no loss or damage to the other set of keys and no insurance policy is going to pay so as to prevent a possible future loss. The policy does not cover losses that have not occurred.
