The bottom passage-lock mechanism jammed the interior handle shortly after I had completed the installation, essentially locking me in the house. Luckily I was able to enter from the outside using the key. The mechanism still doesn't work properly. I don't have the time or patience to deal with returning and replacing it right now. I had the same problem with the house's original lockset. I basically replaced one headache with another.. Jeff. San Leandro, CA. Sun Jul 05 2026
