Storm Door Lock Replacements

We need to replace the lock on our storm door which has broken. There is no name, number or any other descriptive information on the broken lock. We found a lock on your website (Product Code: 40-039S) that we think might be the same size as our broken lock according to your dimensions indicated. We would like to order three (3) of the replacement locks if you have them or know a place here in Houston that might carry them. We would also like to have all 3 locks keyed to use one key.

Thank you for your time and assistance and I look forward to hearing from you at your earliest convenience.
