Best Spray for Unjamming Apartment Door Lock: Graphite Powder vs. Teflon Spray vs. Silicone WD-40

The lock on the door to the apartment began to move hard, namely, it is difficult to insert and remove the key.

On the Internet, they recommend graphite powder (advised by the seller in Obi) and Teflon spray. There is no Teflon spray in Obi, but there was a silicone WD40 (yellow) recommended by the seller - but for PLN 43. For that, I can buy any Teflon spray from Allegro with shipping, if it's better.

What is best to take?

Vaseline grease

Even the butter will help quickly. In the long run, it doesn't make sense anyway, the grease wipes off during use.

It would be much better to remove the insert and even an ordinary one WD40 take a good bath.

If the key jams, the cylinder must be changed in time, before the key stops opening it at all

I guess I'll stop looking here. It's not worth it anymore.

As for the lock, replace it with a new one and that's it. Why do you powder a corpse.

I suggest MojeAuto silicone grease. Perfectly lubricates and lasts quite a long time. The price depends on the store's margin, but about PLN 10 for 300 ml + 100 for free. Look for silver packaging (tin), not from the orange-black series.

Maybe the key was twisted or deformed? Someone was playing with it, throwing it?

And I will propose a CPN lock defroster for a short time, if we are talking about the lock insert, and replace it in the near future. Any lubrication is only an extension of the agony of this mechanism. I have worked with the inserts for several years and the only effective and long-lasting effect is the replacement of the lock.
PS when going to the store, it is worth having the dimensions of the insert or the insert itself, and I would not look in supermarkets only in specialist stores.

WD40 is a kerosene-based grease remover, Teflon greases are too thick and you can damage the lock, acid-free petroleum jelly or silicone grease.

And since when are the inserts lubricated?

I use militec 1, or molybdenum, i.e. molybdenum disulfide.
No lubricants, petroleum jelly, silicones, etc. crap.

It depends on many factors - there are those where you lubricate, there are those that you do not lubricate ... I know what my friend is talking about, but seriously - sometimes it is worth approaching the problem practically.

Better than molybdenum disulfide is boron nitride ...

I use "GERDA locks and cylinders maintenance agent". Actually, I used it once, after 10 years of using the lock, I think. The guilty party was a slightly bent key (by a 2-year-old child).

This silicone grease for PLN 43 (OBI Castorama etc.) is often available in smaller stores for PLN 14 ... Generally, all large DIY stores impose a gigantic margin on them, as well as many other products. Only often it does not pay off to look for: /.

Look carefully at the key. After prolonged use, small burrs (flashes) appear on it, which make it difficult to insert and remove the key.
The needle file handles them very well.
My castle is flying like new.

As a year ago, I treated the lock with silicone oil W5 for about PLN 5 from Lidl. So far it works flawlessly.

Everything is good, but these are temporary measures, all lubricants cause the deposition of dust - dirt and this kills the insert

Dirt, dust, rubbing parts settle in the insert anyway - that's why you have to do everything with your head and not spill the grease so that everything sticks together.

I understand what my colleague is talking about, but after decades, rinsing the insert with even kerosene shows that there is some dirt there.

I have very bad experiences with the use of the above grease at low temperatures.
Locks in the car froze below -15 ° C.
Only rinsing the above specific with kerosene eliminated the problem.

But replies, thanks!

Only yesterday I rushed a little and ordered this silicone yellow wd40 (in another store they were only blue and not yellow). But if this would help, I can still buy this Gerda or Militec liquid.

Even if the key is bent, it has already cut the insert, because the other 3 keys also have a problem.
Well, but after examining the keys, I find that they have definitely poured a lot of dirt into the cylinder. In addition, a neighbor who lives a meter and a half away had recently made a door with a frame replacement and was heavily soiled.

It is compressed air and kerosene / extraction gasoline for washing (I am using a brake cleaner).

A syringe with a needle, extraction gasoline and isopropanol. For this multiple insertion and removal of the key. And if the insert is not worn inside, it will be as good as new. We don't lubricate anything.

Once, when I was still living in a block of flats (35 apartments in a cage) and after about 3-4 weeks, no one reported a failure of the intercom liner to the cooperative, which was terribly irritating (and already then I lived in a new apartment and I used to visit the old apartment once or twice a week ) so I don't understand how the people using the wrench lasted that long. Anyway, I took the above-mentioned assortment, went under the cage (during the busiest hours, so that as many neighbors as possible could see me at work) and "repaired" the insert. It cost me 15 minutes, then I printed the list of tenants and walked around the cage, charging a symbolic PLN 4 per apartment. If I replaced the cylinder, everyone would have to pay 8PLN for one additional key, and it is known that there is more for one apartment. And also the cost of a decent insert.
As a result, I got a few zlotys and the neighbors were satisfied with my resourcefulness.
End of OffTop.

In a similar situation, I took the insert out and turned it over. And I didn't make a stitch on this occasion

I had turned the year before because it was so scratchy that no cleaning gave any result. And then it was in a community action
As everyone benefits, and only I became interested when the problem occurred, I think that after the second "repair", the symbolic PLN 4 is probably not some barbarism

Once upon a time in "Rock Radio", if I remember correctly, there was a discussion whether waiters / waitresses should account for tips as income, despite conversations with lawyers and several phone calls to the US, it was not possible to clearly answer the question.
At one point the listener called and said that he was a pizza delivery man and he often delivered to the US, every time he gets a tip he has doubts whether to accept, because after all it is the Tax Office, and the amount on the receipt is the amount on the receipt ...

Let's not get paranoid.

Ps.
I found an abandoned 2PLN in a shopping cart. I couldn't find the owner, so whether I wanted it or not, I got rich. How should I put it in next year's settlement. I must admit that it happened to me 3 times this year, and I found a zloty again, all in the same shop.

I took out the liner and cleaned it with that silicone WD 40. I couldn't get out / rinse any rubbish. The castle is 8 and a half years old. So he certainly did not have 100,000 scams that he supposedly withstood.

The key works fine, but has to be removed very gently. In the long run, this is unlikely to help.

We are just different - I would not go to delete people, since none of them ordered a service from me, that's all.
Some have a business sense, others not so much in the subject.
