It is only possible to obtain a combination for a Master Lock if it has a serial number and is not attached to an object. In this circumstance, the lock should be taken to a Master Lock distributor, who can provide the combination.
The first option for obtaining a lost combination for a lock with a serial number is to take the lock to a licensed distributor or retailer. The distributor can obtain the combination from Master Lock on the customer's behalf. The second option is to submit a Lost Combination form available through the Master Lock website. This form must be completed, notarized and mailed to Master Lock. The owner must make a photocopy of the lock to submit with the form. It takes four to six weeks for the combination to arrive.
If the lock has no serial number or is attached to an object, then the lost combination cannot be recovered from Master Lock. However, a professional locksmith might be willing to try to pick the lock and recover the combination. If all else fails, the owner may simply need to buy a new Master Lock. To prevent this circumstance from occurring, the combination should be written down and stored somewhere safe.
