A common question we get at MasterLocks.com is, “I lost my keys, can you send me a new set?”

 

Step 1: Find Your Key Number

It is only possible to obtain a replacement key from Master Lock® if you have the key number.

Your key number can be found on the back of your key or on the original packaging.

For example, this key number is 3900. If your key is blank it is possible that it is a duplicate key, which only a locksmith will be able to help you copy.

 

Step 2: Call Masterlocks.com

Once you have your key number, you can call MasterLocks.com’s customer care at 1-800-358-0508.

Or if you know your key model, you can visit MasterLocks.com and purchase the correct cut key.

If you do not have the key number, it is possible to get an impression of your lock by a locksmith or a local hardware store. Please note that not all locksmiths will offer this service, and if they do, they will charge you a fee.

For your security, there is no such thing as a “Master Key” that opens all Master Locks.

1525 Replacement Control Key

For Schools and institutions that purchased Master Lock No. 1525 locks may order key replacements. However, they need to confirm their end user information before purchasing more keys. This may require sending a handwritten or faxed request for the keys on the school’s letterhead or sending an official PO. Please call MasterLocks.com’s customer care at 1-800-358-0508 for assistance with this process.
