Lost Keys
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.
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.
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
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.
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.
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.
