Master Lock® Lost Keys and Key Replacements

26 Sep


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

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.

Once you have your key number, you can call’s customer care at 1-800-778-2217.

Or if you know your key model, you can visit 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.

Several companies have found it beneficial to custom engrave their lockout/tagout devices for identifying purposes. For example, some companies imprint an employee’s name into the lock to indicate who is servicing the machine. Alternatively, some companies create a code to correlate the lock to the corresponding key. Both options gives the supervisors the ability to identify the right person or key to unlock the padlock.

The 1525 and 1502 Locker Locks have room on the dials’ faces for customization.
