Grainger has contacted the product supplier and have been advised by them of the following: Submit a Lost Combination Form
• Confirm that your lock features a serial number prior to submitting a Lost Combination Form. Please see examples of a serial number if you are unsure if your lock features one.
• Print out the Lost Combination Form from a Printer Friendly Page or download a PDF file.
• Have your Lost Combination Form notarized by a Notary Public to prove you are the owner of the lock. You can include up to 6 combinations on one notarized form.
Note for inmates at a correctional facility: In addition to the Lost Combination Form, you must submit your request on official prison facility letterhead. In lieu of notarization, the Lost Combination Form must be signed by a prison facility official.
• Submit your form to:
Master Lock Warehouse
1600 W. La Quinta Rd
Suite/WHSE # 1
Nogales, AZ 85621
• Once the request is received, your combination will arrive in approximately 4-6 weeks.
