  • To improve the function of a lock-turning mechanism, and facilitate its use;

How often do locks need to be oiled?

How to lubricate the door lock with their hands - How to lubricate entry doors and what to useIt will be sufficient to lubricate an interior door lock once a year. But as for the entry door, situated outside of the house, it needs to be taken care of more regularly. NB: oiling can sometimes make problems with the lock worse. Metal dust may stick to working parts of the locking-mechanism along with the lubricant, and this can have bad consequences.


Precautionary measures

In general, many modern locking-mechanisms rarely need to be oiled. But if the door lock does need some maintenance, you should use only special compounds, since badly-chosen products can eventually make the mechanism inoperable. In any case, everything that is required for maintaining a lock should be noted in the instructions.

Locks don't always need to be lubricated. For instance, if the lock works smoothly when the door is open, but the moment you shut it, the key hardly turns, then the problem isn't probably connected with the lock, but with the door. Most likely caved in or became twisted. Lock malfunction isn't often connected with a lack of oil! Sometimes its wear simply reaches a critical point. The lubrication of contact points can do well only in those parts of the lock where it is actually needed.

  • Without oiling, the bars of the lock get worn out from constant rubbing against the chrome surface of the ends of the lock bar;
  • An unlubricated push-pin gnaws out a dent on the sliding surface, when being pulled;
  • The lubrication extends the service life of the vertical drives (pistons);
  • The knot of the lock, regulating the beveled latch, constantly suffers from rubbing, when the latch works;
  • It is recommended to cover the pivots with lubricant, as they also suffer from abrasion;
  • The toothed bar of the cylinder lock works much better, when lubricated.

The whole procedure of cleaning and oiling is rather simple. First of all, you should put a lot of cleaning substance into the lock barrel, insert a key in the lock, and then immediately remove it. Afterwards, wipe the key and repeat the procedure once again. Keep doing it, until the surface of the key stays clean. The process of oiling the locking-mechanism is just the same. You should open and close the lock a few times, so that the lubricant spreads and dispenses.

Graphite powder - How to lubricate entry doors and what to use

It is not recommended to use ordinary lubricants for this type of locking-mechanisms, as the lock may get jammed, when the substance dries up. In this case, it's better to use dag (in other words, graphite dust) as a lubricant. You can get it by milling the core of an ordinary pencil, but is there any use? Every specialized store sells a good graphite lubricant in a spray can. It reduces friction between moving surfaces, protects from dust, and prevents parts from corrosion. Silicone aerosol is also very effective for oiling such type of locks: due to its capacity to repel moisture, the aerosol provides smooth sliding, and protects the metal from corrosion (NB: it is better to overspay the aerosol with a little tube).

What to use for lubricating a cylinder lock?

Cylinder locks require only oiling a latch. For this purpose, one usually uses WD40, but it dissolves fast, and thus has to be systematically renewed. This substance has a high capacity for water repellency, and effectively protects parts from corrosion. Silicone spray is also good for oiling lock cylinders.
