Lost Keys & Key Replacement FAQ

Q: How can I get a new key for my lock if the locksmith or hardware store could not find a replacement?

A: It is not always possible to get a replacement key for every model of lock. If your hardware store can not get one for you, please check with a local locksmith. If they are also unable to get a replacement, you may have to purchase a new lock.

Q: We lost both keys to our lock during a move. Now we are unable to get some important records out of storage. What should we do?


If you did not record the key number, which was stamped on the original keys that came with your lock, it is not possible to obtain replacement keys. Contact your local hardware store/locksmith for removal. If you know the key number, a hardware store/locksmith can duplicate most keys.

Q: My hardware store no longer provides key replacement service. What should I do now?


Occasionally, a store will stop offering this service due to lack of demand or time constraints. In this case, we suggest calling a locksmith who is used to handling this type of request. To save time, always call ahead to ensure that your particular store provides these types of services.

Q: Can I order a new lock that will work with my existing key?

A: It may be possible to order products that can be opened by an existing Master Lock key. Take your existing key and lock to a hardware store (Ace, True Value, Do it Best, etc.), locksmith or other outlet that sells Master Lock products. Ask them to order the product with the same key number that is on your key. Please call ahead, as not every retailer will provide this service.

Q: I've lost the keys that came with my lock and I do not know my key number. Can I send my lock to Master Lock to have keys made?

A: Without the key number, there is no way for Master Lock to know which key will open your lock. There is no such thing as a Master key that will open all Master Lock products.

Q: I have a combination lock that has a keyway in the front or the back. Is it possible to get a key for my lock?

Q: I lost the keys for my padlock. Is it possible to obtain new keys?
