How to lubricate door lock?

Question

My door lock needs care, the key is hard to put in.

I've got this in my previous apartment and I got some 'magic cream' from a friend which worked like a charm, but unfortunately, I don't have this anymore and I haven't noted what was this.

What kind of lubricant works fine for door locks? I don't want to get it stuck more.

Graphite power usually works well, does not drip like oils. If key is hard to put in, instead of turning, might be damage to the lock or key. — crip659, Jan 09 '22 at 17:54
I use WD-40 or a similar product. You don't need much. Just spray a little on the key and insert it into the lock, and turn it repeatedly. — Michael Harvey, Jan 09 '22 at 21:00
Oil holds onto dust, causing future problems. A drop on the key itself might not be too bad, but *not* in the lock. As @crip659 states, use graphite or powdered PTFE. — DrMoishe Pippik, Jan 09 '22 at 23:39

In addition to graphite powder, other lubricants for door lock mechanisms include silicone lube, grease lubrication, and Teflon-based lube. A penetrating liquid like WD-40 or white lithium grease is another option. Consider the local weather conditions before selecting a suitable lubricant.

I wouldn't put any grease or oil in a door lock mechanism. It'll just make a mess, including on the key, which you then put in your pocket or purse.
