C220 Smart lock keeps jamming.

My C220 smart lock keeps jamming. Some days it works flawlessly, some days lock jammed. I live in an apartment building, and one tenant lives in the dark ages, and uses the key quite often. I also notice, that when it’s raining, and moisture in the air, is when this occurs. Don’t know if my door is swelling from moisture, but I have bowelled out the female cavity some more to accommodate more room for the bolt. Anyone else have this issue?
