Searching for missing key for marks storm door

A quick learner says:
We moved into this home and the prior owners did not leave a key for the Marks iron storm door. The home was built in 1996.

What are my options? Can I find a number somewhere for key identification? If not, will the cylinder be able to be replaced without a key?

Thanks,
Sue

Take a look at our 40-123 key cylinder and see if it matches up to yours. I'm not 100% sure this is what you want, but it was the closest I could find. This comes with its own keys.

If that won't work, then a local locksmith may be able to help you.
