I have an older home, and found a Weslock door knob on one of my doors that I wanted to swap out with a locking knob made by Defiant. At the local Home Depot, the only two brands of knobs that I saw were Defiant and Keystone. I don't know if Weslock still exists, it might be rare. I attempted to remove the Weslock knob, but to my frustration I could not figure it out.
Google is your friend, right? A quick search for how to remove this knob came up nil. I came across a forum that vaguely spelled out how to remove this. I think a step by step guide with pictures would help. It annoys me how vague a description is. When someone asks how to do something, don't give them a vague answer assuming they know what certain technical terms are. Define things, or at least show pictures. Well, here is the guide to removing a Weslock knob that I encountered (non-locking, no key). It's straightforward, you just need to locate where the secret elements are.
Step 1: Remove the Side Plate
This is where you see the "Weslock" name. There's two philips screws to unscrew, and then you can pry it out. However, underneath is something that looks like another plate. This is permanently affixed, so don't bother removing this. I found that out after viciously trying to pry that off!
