Lost Combination FAQs

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

A:

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, 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.

B) My lock has a serial number:

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

Q: I've lost the combination to my "Set-Your-Own" combination lock. Can you tell me what it is?

A:

Resettable combination locks have a combination that is assigned by the owner of the lock. Therefore, Master Lock does not have record of the combination that the owner set. The lock cannot be reset unless it is in the open position. If your lock is attached to something, you will need to call a locksmith for removal. Please note that Master Lock does not reimburse for Locksmith services and/or fees.

Q: Can Master Lock reset my "Set-Your-Own" combination lock and send it back to me?

A:

Unfortunately, your lock is a "set-your-own" combination lock. Once you have set the combination, we cannot reset it for you!

Q: I've lost the reset tool for changing the combination on my resettable lock model 175, 176, 177, or 178. How can I get a new one?

A:

Contact your local hardware store or locksmith. (Master Lock's part number for the reset tool is K175).

Q: Someone was playing around with my resettable combination lock and accidentally reset the combination. Now, I don't know the correct combination. Is there any way to reset this lock back to "0" and assign a new combo?

A:

Unfortunately, this lock is not resettable without knowing the combination that was assigned by the owner. It's most likely that you will need to purchase a new lock.

Q: Is it possible to obtain a combination chart on CD or via e-mail?

A:

Yes, it is possible to obtain a chart on CD or via e-mail. To obtain a new combination chart booklet, send a request to safetyeucs@mlock.com. Please allow 2-4 weeks from the receipt of the request to process your chart.
