Remove interior knob - HOW?

I have a Schlage lock on an exterior door where the inside knob has a chip on the finish.



The lock still work fine except the chip.

Now a few years ago I had the same lock (on another door) where the inside knob "button" just "spins" freely. At the time I called Schlage and they sent me a free replacement which I installed and I did not throw away the bad lock.

So now I am wondering, can I take the interior side of the bad lock, remove only the knob (the silver sphere) and exchange it with the one I have which has a chip? I can't figure out how to remove the knob. There are two recessed slots but pushing in with a flat head screwdriver does seem to free it. Is there a trick? Or do I need to replace the whole inside half which means I can't do it because the inside button on the old lock is bad.

 

That looks like the handles I've installed in my home. A simple stubby or flexible screwdriver, remove the two screws shown in the picture, and the two halves come off.

 

A right angle phillips screwdriver is best. You have to remove/replace that entire interior half, or if that's not possible, get a new set.

 

Sorry I was clear in my original post. I don't have a problem taking the two halves apart with the two screws on the inside.

Right now what I have is:

EXISTING: working, functional set where the interior knob has a chip.
SPARE: a non working set where the interior "button" spins but the knob finish is fine.

I was hoping I can further remove not the entire interior half but only the interior metallic sphere (not the button, not the base, nothing else) and replace just that sphere with the spare non-functional set.

Here is an illustration of what I am trying to remove.



It appears most knobs have two knob retainer holes to insert or detach the knob from the rest of the lock. Yet I tried jamming my flat head screwdriver into those two slots and it didn't seem to disengage anything.

 

If you know a locksmith they might have what you need in their junk pile. Otherwise just buy a new doorknob assembly. They are so inexpensive that individual parts are not sold.

I don't think your doorknob photo is the same as the diagram you posted. Your doorknob appears to be an inexpensive model that can not be disassembled. With more expensive ones you can remove just the knob but even then I've never seen the knob sold as an individual part. When something is wrong you replace the whole thing.

 

I don't need to purchase a part. I have the IDENTICAL lock set in my hand that's broken in the interior button. In other words, I already have a replacement part if only the metallic spherical shell of the knob on the inside can be disengaged somehow.

I see two slots on the side that seems to be on almost many different brand door knobs. My knob has that too on the side. See my picture below.



So I am wondering, are those slots not for releasing the knob? Or is a special tool required?

 

We are trying to tell you you do not have that type of knob! Unscrew it.

Your illustration is not represntitive of this particular knob. Unless there is something we aren't seeing on the opposite side of the photo.

 

Pilot Dane is "right on the beam" (old flying term)....I can't swear to it, but the inexpensive model you have has the rosette and knob stamped together as one piece...I think that indentation you see on the throat of the knob is where it's stamped to the spindle. If you remove the inside assembly and look at the back side if the knob, I think you'll see where it's bradded or peened onto the rosette. If I'm wrong, you'll see a circlip holding the knob on to the rosette, in which case you may be in luck.

As others have pointed out, the exploded view is of a heavier duty Grade 2 lock. It's a different animal.

 

If you have another knob assembly as a parts donor then you would swap the whole knob assembly. You can not separate just the knob with the lock in your photographs.

 

well, I took the lock apart and yes now I see I can't make it work. There seems to be no way to disconnect the knob from the button cylinder (not sure what the proper term is).



Yes I do have a part donor, but unfortunately the part donor is a lock with a broken inside button, and the existing lock has a chipped knob. So I think I need to get a new lock then rekey it to match what I have.

I just got confused when I saw the slots on each side of the throat thinking this is where I can release the knob only. Turned out it's not as rstripe said.

 

They are cheap. Just replace it with a new one.
