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.

Default Pipe wrench...............

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.

I just took off a Sargent Door Knob after 2 hours of wrangling with it. At one point I consider sawing it off until I realize it would take days. Anyways, to restate points already made, it was an older lock probably installed 1980s. One side is key entry and the other a push button lock.

The first step was to pry off the face plate on the same side as the push button lock. This revealed 2 phillips screws which I loosed. The latch part actually fell off at this point, but I couldn't get the door knobs off. With newer locks often you just pull the 2 knobs apart, but I couldn't. The key was to identify a small hole on the same side as the push button lock (on the cylindrical part of the knob leading up to the actual door knob). I initially pushed in with a paperclip, but it didn't work, because you need a larger surface area. I finally just eyebrow tweezers and pushed the the pin in and that side of the knob slips off.

Basically the way the locking works is that the knob has a cut out small hole. On the cylinder side, there is a pin that is popped up all the time, but can be pushed in. when the knob slides on the cylinder, it will depress the pin and then the pin popped up through the hole, stabilizing the 2 parts together, until you press the pin part back again and slide it out of the cut out hole on the knob side.
