Hello @zillah 

Thanks for sharing your question about your door knob. Since you have sprayed the latch with WD40 and the results were minimal, I propose installing a new entrance door lock such as the Eufy Black Security Smart Lever Lock C33 or for a more traditional lock the Lockwood 31-55mm Satin Chrome Entrance Lever. 

I also suggest looking at the Door Lock Installation Service if you wish to have your door lock professionally installed.

If you need further assistance, please let us know.
