Lost keys to my lock set

I believe the 40-123 could fit your handle set. This is a generic type of key cylinder that works on many different handle sets. Look it over and see if its dimensions line up to your hardware. We also have a video on installing a storm door handle set you may find helpful, which you can see on the right side of this page. Finally, if all else fails, check with a local locksmith or hardware store in your area. They might be able to re-key your existing key cylinder.

Unfortunately, we do not sell replacement hardware for this kind of door. I highly recommend contacting the original manufacturer for assistance.
