This is Larson 3/4" thick storm door with Factory handle hardware. I have been to Lowe's, who called Larson, there is NO replacement parts for this door. I'm looking for something I can lock with a key From outside, and also lock inside. Thank you for reply back and hope you can help me with this matter. I have no other info on this door. Was on the house when I bought it
Thank you
Gail
