DNS Industries 13/23 outside pull standard lock cylinder

A home owner from New York City says:
I don't have a key to this cylinder, which is 3/4" long and has the number 137 stamped on its face. Would you have a replacement part? Or can a key by made from the cylinder?

Hello! I'm afraid DNS is no longer in business, so replacement options for these keys are limited. You might want to take this to a locksmith first and see if he can help you out. If not, our 82-302 key tumbler may work for you. It comes with two keys.
