- I've forgotten the combination to my standard dial combination
lock. How do I obtain the combination that I use for personal use?
Due to increased security concerns nationwide, Master Lock recognizes
the heightened need for additional safety measures. We no longer provide
lock combinations in response to phone, fax, or email requests. Please
follow the procedure outlined below to obtain the combination to your
lock and submit your request to:

Print out the Lost
Combination Form, or
download the PDF
Have your Lost Combination Form notarized by a Notary Public to prove
that you are the owner of the lock (you can include up to 6 combinations
on one notarized form).
- Note: Inmates at a correctional facility - in
addition to the lost combination form, you must submit your request
on official prison letterhead.
In lieu of notarization, the form must be signed by a prison official.
• Photocopy the serial number on the back case of your combination
lock. This copy MUST clearly show that the lock is not attached
to anything. Be sure to hand write the serial number on the photocopy.
• Mail the original completed, notarized Lost Combination Form and the
photocopy of the back of your lock to the address above.
* It will take approximately 4 to 6 weeks to process your request
for a combination.
Note: If the form is not fully completed and notarized with a raised
seal or rubber stamped seal, or if the serial number is not legible
on the photocopy, your request will not be honored. Master Lock does
not reimburse for any Notary fees.

- Someone was playing around with my resettable
combination lock and accidentally reset the combination. Now, I do
not know the correct
combination. Is there any way to reset this lock back to "0" and
assign a new combo?
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.
*Once the lock is set, there is no way to open it without the combination.
Please make sure you record your NEW combination in a safe place.

hardware store to order keys. Please note that the locksmith will charge
you a fee for this service. Not all Locksmiths/Hardware Stores offer
this service; please phone ahead.

How can I get a new key for my lock if the locksmith/hardware store
could not find a replacement?
It is not always possible to get a replacement key for every model

with a local locksmith. If they are also unable to get a replacement,
you may have to purchase a new lock.
The hardware store no longer provides key replacement service. What
should I do now?

of demand or time constraints. In this case, we suggest calling a
locksmith who is used to handling this type of request. To save time,
always call ahead to ensure that your particular store provides these
types of services.

that will open all Master Lock products.
