There are some cases where a locksmith will be covered, such as:
Keep in mind, if you only need your key or lock to be replaced and the value of the services is less than the homeowner’s deductible, you would want to pay for this out of pocket instead of making a claim.
In your situation, it may save money in the long run, to have a few extra keys make and give the spares to a couple of trusted friends or family members. This way, they can come to your rescue for free if you were to get locked out again.”
