How and how to lubricate the front door lock?

Bad things happen to everyone. It happens that you are in a hurry to go home, strive to unlock the front door as quickly as possible, but it suddenly does not open. And the point is not at all that the mechanism has broken down or you have confused the keys, it happens if you do not lubricate the door lock for a long time.

Any door hardware must be periodically lubricated, and such work should be carried out not as difficulties arise, but regularly, in order to avoid many troubles with the lock. It's not a secret for anyone that this particular detail plays the most important role in ensuring the safety and security of the home, and when the castle fails, a potential threat arises both for the house itself and for its inhabitants.

Lubrication is carried out for the following purposes.

• For sliding - the use of a lubricant facilitates the free rotation of the mechanism and its operation.
• To reduce the degree of wear - if there is too little lubricating fluid in the lock, then the entire operation of the system is difficult, while the parts begin to rub in, chips fly off the metal, and dust particles begin to get inside, which act like coarse abrasives.
• To combat dust accumulation - when there is a lack of lubrication, the particles begin to stick together into solid lumps and completely block the free movement of the unfolding crossbars.
• To prevent rust. Corrosion of metal is the main enemy of every mechanism made of metal, it leads to complete or partial destruction of the material, in this case all the elements of the lock seize, or even stop moving altogether.

As a rule, lubrication is carried out "after the fact", that is, when there have already been some problems and inconveniences in using the lock. This can give temporary relief, but the problem will not solve and, after a while, it will again make itself felt.

In order for your lock to serve as long as possible, it is necessary to carry out a preventive coating with lubricants at least once a year. Entrance doors must be processed more often, this is especially true in high-rise multi-storey buildings: here it is worth processing the fittings every 6 months, but the owners of cottages and private houses must conduct inspection and processing on a quarterly basis.

The modern industry offers a wide range of different lubricants. Let's consider the most effective ones.

• Silicone Grease - This compound is recommended for use with cylinder head locks. Thanks to silicone, all elements of the mechanism can be turned softly, but at the same time clearly. In addition, silicone tends to repel moisture, so its use significantly reduces the likelihood of corrosion.
• Graphite grease - a composition that has proven itself quite well for old type locks. By the way, instead of such a lubricant, you can take a regular pencil lead, it helps to cope with the jamming of the lever-type locking mechanisms.
• WD-40 - a universal compound that will protect against many problems with the operation and use of the lock. The tool makes it easier to turn mechanisms, repels moisture, and in addition, corrodes corrosion.

• Solidol - better known as calcium grease. An effective tool to facilitate the use of the lock.
• Lithol - lithium grease, which is characterized by exceptional resistance to water. In industry, it is used for bearings, however, in the case of the lock, there will undoubtedly be a lot of sense from using such a lubricant.
• Machine oil - often used in everyday life, has a proven effectiveness.
• Gun oil - advised for the lubrication of external keyholes, as it works effectively even at extreme temperatures.

As an emergency, you can resort to improvised means.

• Vegetable oil. Of course, this composition can hardly be called a lubricant in full, but it can be used as an emergency measure. But for the prevention of breakdowns of the mechanism, it is better to dwell on other drugs.
• Fat. The melted fat can become another lifesaver that will provide a temporary solution to the problem, but you should not use it on an ongoing basis, otherwise the fat will accumulate, and the work of the lock, on the contrary, will become even worse.

It is very important to select a lubricant based on the design features of the locking device itself.

• Lever mechanisms should be processed only with dry compounds. If you use oil, it will quickly absorb dirt and dust, which will lead to further damage to the device. In this case, it is necessary to opt for graphite powder.
• Bronze cylinder mechanisms less demanding on lubricants, however, the choice of the drug should be approached the more responsibly, the cheaper metal was used to make the lock. For cylinder constipation, it is best to purchase a silicone lubricant in the form of a spray, WD-40 has proven itself well, although it evaporates quite quickly, which is why such a lubricant needs to be periodically renewed.
• Combination locks are also subject to mandatory lubrication, they even have special holes for entering the compositions. It is optimal to use aerosols of deep penetration, for example, WD-40 and UPS-1.

The keyhole must be cleaned before lubricating the door lock. To do this, you just need to pour in a special cleaning agent and wait for the allotted time, as a result of the action of such a tool, all dust and dirt begins to come out. The composition should be introduced abundantly, so that all the litter has the opportunity to come to the surface.

To finally get rid of the blockages, you need to put the key into the door slot several times, wipe off all the accumulated dirt from it and repeat the procedure until the well is completely cleaned. Immediately after this, it is necessary to very carefully pour or inject grease into the lock, get wet all the excess, otherwise they will simply spread over the surface of the door. After that, insert the key and turn it repeatedly in all directions, then remove and wipe dry. Be aware that grease may remain on the key over the next few days, so make sure it does not stain your clothes.

However, this only works if you are doing scheduled work.But if you have a force majeure, and the key is jammed, then you should first try to pull it out. To do this, gently swing the key from side to side without making any sudden efforts. If the key still remains in the lock, then you will have to disassemble the mechanism and remove the larva itself from it. If you feel that you are unable to cope with the problem on your own, seek professional help.

Now that we have identified the need for periodic lubrication of door locks in the apartment, we should focus on lubricating the hinges. Their regular processing allows not only to significantly extend the life of the fittings, but also often eliminates the unpleasant creak of the door, which often makes itself felt in doors of various types.
