Lost Keys

I lost the keys for my Master Lock padlock. Can I get replacement padlock keys?

You can securely store your combination or key number with us so that you never lose it. If you lose your key, the number can be used at a locksmith or a hardware store for a new one.

If you still have a physical key, you should be able to get it duplicated from a local hardware store or locksmith. If you don’t have a key to reference, then another option is knowing your key number to place a special order via a authorized distributor.

If both are not an option, then contacting a locksmith to open or remove your lock would be your resolution.

I lost both keys to my Master Lock lock (non padlock). Now I'm unable to get some important items out of storage. What should I do?

If you recorded the key number, you may be able to get replacement keys from a hardware store or locksmith. If you didn't record the number, contact a locksmith to remove your lock.

Please note there will likely be a fee for this service.

I lost the keys to my Master Lock lock and don't know the key number. Will Master Lock send me a replacement?

No. Without the key number, there is no way for Master Lock to know which key will open your lock. There is not a master key that will open all Master Lock products.

Key Replacements

Can I order a new Master Lock lock that will work with my existing key?

Most lock models have an option to match an existing key when ordering new locks. With a wide variety of locks Master Lock offers, we recommend contacting a distributor or our call center for confirmation.

My hardware store no longer provides key replacement. Can I order replacement keys directly from Master Lock?

We do not supply replacement keys directly to customers. Instead, you may try another hardware store in your area or contacting a locksmith to see if they can produce a replacement key.

My hardware store could not get a new key for my lock. What should I do?

Check with a local locksmith to see if they can duplicate a replacement key. Sometimes, replacement keys are not available for every model of lock. If this is the case, you may need to purchase a new lock.
