There's a vulnerability in Master Lock branded padlocks that allows anyone to learn the combination in eight or fewer tries, a process that requires less than two minutes and a minimal amount of skill to carry out.

A) My lock does not have a serial number

1. The Master Lock chart references the key cut to the lock serial number. Your organization may find it useful to keep records by serial number of which employee is assigned a specific lock. Please contact Master Lock Customer Service to define and order your Master Key System at 800-308-9244.
2. If you are need of a new combination lock, visit us at Masterlocks.com to purchase one at a great price. If your lock does provide a serial number, the easiest way to retrieve your combination is to take your lock to any local Master Lock Distributor in your area; think of Wal-Mart, Home Depot, Lowes, etc. A store associate at the customer.
3. Find the Combination to Your Master Lock!: Here's an experience I, and most high school students go through at some point in their life. You wake up in the middle of the night, and remember that you need a padlock for P.E.  You quickly rummage through all the junk in.
4. Means 'remainder.' The magic number with Master locks is four. You need to find the modulus of the last digit of your lock and four. For my lock, the last digit is 19. Let's do some long division! 4 into 19=4, and 4 times 4 is 16, and 19-16=3, so we have 4 remainder 3. So, 19 Mod 4 (sometimes stated 19%4) is 3.

To provide enhanced security long-term, Master Lock discontinued imprinting a serial number on the lock body of combination locks sold through retail locations. For greater convenience, we encourage consumers to store their combination(s) at our secure web site, 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.

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.
