Sargent door knob removal (paint, installing, glue, pipe)

[nsharman]

Has anybody tried un-installing a sargent door knob (probably 15 years old). I can't get the model number. I have been able to unscrew the plates but the central core is still fastened to the handles on both sides. I have tried many different thing and none seem to work. Any ideas?
Thanks

I am not familiar with the brand. But I have recently removed several door knobs and the first step is to find the small slot/hole called the Detent. Insert a thin screwdriver into it and push while using your other hand to pull the door knob. It should detach at that point. Then you unscrew any screws. Might take a couple of attempts.

Some of those plates do not pop off, some are threaded on.

Even if they pop off, lots of times are stuck in the paint / finish of the door like glue.

The solution when you don't know what to do is get a pipe wrench or something like it that with teeth that can grip into it. Try turning it, to the left or counterclockwise, they should have standard type threads.

Whatever the cause, it will either turn off as in threaded or if pop off, come off as you turn. The amount of force needed can surprise you.

Need to use care, tricky to grab the plate with the wrench without marking door. Open door so you can stand by edge, turn a wee bit at first with force to break it lose and give an indication of threaded or pop off.

Tougher to describe than do.
