I'm replacing the doorknob on my front door; I like the look of this lever, but it's described as
For use on interior doors requiring no locking functionality, such as hallway or closet doors.
I have a deadbolt, so don't feel the need to spend the extra $30 on the locking variant which is described as
For use on exterior doors where keyed entry and security is needed.
As far as I can tell the materials are the same and I should be okay using the non-locking lever. Obviously it depends on the product, but generally speaking is "for use on interior doors" just a recommendation based on security needs? Or is there some reason I should get the locking model?
