If you do not know the key number, it is possible to obtain additional keys from a locksmith who can impression your lock. If you do know the key number, go to a locksmith or local hardware store to order keys. Please note that the locksmith will charge you a fee for this service. Not all Locksmiths, Hardware Stores or Home Centers offer this service; please phone ahead.

Q: I've forgotten the combination to my standard dial combination lock. How do I obtain the combination for personal use?

To provide enhanced long–term security, Master Lock has discontinued imprinting a serial number on the lock body on combination locks sold through retail locations. For greater convenience, we encourage consumers to store their combination at our secure website, Masterlockvault.com, which is easy to use and offers 24/7 access. Unfortunately, we are unable to provide combinations for non–serialized locks. Please see examples of a serial number if you are unsure if your lock features one.

Please send your request to Master Lock and provide model and serial numbers.
