Frequently Asked Questions

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



A) My lock does not have a serial number:

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,, 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.
