Full Answer

Master Lock releases combinations by phone only to authorized dealers acting on behalf of the lock owner. If the lock is attached to anything, the dealer cannot provide the service. For written requests, Master Lock requires a Lost Combination Form which is printable from the company website. The form requires a notary's signature affirming that the person submitting the form owns the lock.

Master Lock no longer produces locks with serial numbers and cannot provide the combination for a lock without one. For this reason, the company provides a free combination storage service at its website.
