I just moved into a new house, and one of the door knobs (looks like it's from Schlage) functions perfectly for my needs. I love its setup, but I'm trying to identify the specific model or function type so I can get another one. Here's how it operates:
- It's keyed on the outside.
- It has a thumb-turn on the inside.
- When the thumb-turn is in one position, I can turn the inside knob and exit without any hassle, but the outside remains locked, needing a key for entry.
- In the other position, both the inside and outside are unlocked, allowing free movement for anyone.
This setup ensures that the door can stay locked from the outside even if someone exits from inside, which is what I prefer. However, when I check the Schlage "Keyed Entry" knobs at Home Depot, they seem to operate differently. If unlocked from inside, they unlock both sides; if locked from inside, both sides are locked as well. That's the opposite of what I want. Does anyone know the specific type of Schlage knob I'm dealing with? Any particular function or model name you'd recommend?

It seems like what you have could be categorized as a storeroom knob or a shop lock. They have similar features where the outside stays locked even if someone exits, so searching under those terms might help you find the right model!
From what you’ve described, it sounds like you’re looking for an Office Entry lock (ANSI F109). That kind of function is pretty common and should meet your needs. Definitely worth a look!
You might want to check their website or pull the handle apart to see if there's a model number on it. Sometimes, what you have could be a locksmith's handle set instead of something sold at big box stores.

Yeah, a storeroom setup would definitely work for what you need! Just make sure to check the specific features to confirm it's the same.
