How to fix a lock without help
The time of use, added to factors such as humidity, dust and corrosive agents, can cause the malfunction or the total loss of a lock.
Sometimes we put the locks in the wrong places; subjected to the rigors of the environment and climatic factors; This results in safety implements that end up useless.
A professional locksmith has no problem correcting any damage; His knowledge of the mechanics and operation of locks enables him to achieve this efficiently and in a very short time.
But the idea is to do it ourselves; for which we must have a minimum of notions in terms of basic aspects such as the components and the operation of a lock.
Disassemble, fix and assemble a mortise lock
Let’s start by organizing our homework:
#one. First step: verify that we have the tools and materials that may be required:
- Screwdrivers or screwdrivers.
- Brush or paintbrush.
- Graphite powder.
- Pieces of cloth or tape.
- Kerosene or thinner.
#two. The second step involves removing the malfunctioning lock from the door.
The ideal is to record, by any means, each of the things that we are doing: written or voice notes, photos, videos.
#3. Our third step has to do with dismantling the lock. Also in this case we must leave evidence of our actions; This will allow us to reverse the process without any problem.
- The screws are removed holding the lock cover and removing the internal components in the following order:
- The lever is pulled out bonding, which is the part that presses for the slip to enter or exit the lock.
- Combinations are extracted, one at a time, starting with the first one above, then the second.
- Between the first two combinations and the bottom two is the safety pin; we take out this pin and continue with the following combinations.
- As they are dismantled, each of the combinations must be marked and carefully observed how they are arranged to avoid later mistakes.
- Taking a good look at the position it has, we take off the slip making pressure on the spring that supports them from behind.
- Finally, they are removed the nut and the springs that press it. This nut is the part of the lock where the shaft of the handles fits; it has a cam that actuates the skid.
#4. Step Four: Examine each component to identify if any are worn, broken, or deformed. Sometimes the malfunction of the lock lies in just one faulty part.
- There will be parts of the lock that we can correct any damage. For example, if it is the box that for some reason has been deformed, we can straighten it and get the lock to work well again.
- In the event that there are parts that we cannot fix, we just have to look for them in locksmith stores, taking care to bring the bad part to serve as a model.
- Components that are in good condition, or still have some useful life, we should only clean them well or wash them, if they are very dirty, with an appropriate substance such as kerosene or thinner, and let them dry.
- The rusted parts are treated with sandpaper, taking care to remove all the oxide from the lock.
#5. Once we have repaired everything that we can repair or when we have replaced those parts that have been unrecoverable, we proceed to reassemble the lock.
In the process of rebuilding the lock, each moving component is preferably lubricated with graphite powder; certain greases or oils when mixed with dust can clog its elements and cause malfunctions once the lubricating substance dries.
# 6. When we finish assembling the lock, we assemble it and check that its operation is as desired.
The testimony that we make of each step we take in the process of recovering our lock will allow us to do the same task again, with greater ease, every time we need it.
There are many types of locks; one less expensive than others and with levels of security that correspond to its price. The quality of the device also tends to respond to this factor: the higher the price, the higher the quality.
There are locks that are more popular than others or, in any case, more widely used, both at a residential level and in environments related to commerce and various occupations.
One of the most widely used locks is mortise locks, used on main doors and interior rooms, regardless of the material in which they are made: wood or metal.
This type of locks is also intended to be used in iron bars used in residences: this seeks to reinforce the security of houses and apartments.
The repair of these locks turns out to be a fairly simple task and anyone with little or no knowledge of locksmithing can carry it out without difficulty.
Basically, a mortise lock consists of the following parts:
- Screws that fix the cover.
- The lock box.
- A side plate, attached to the body, with holes for the skid and the pin.
- The slip.
- Safety pin.
- Lever binding.
- Four combination plates.
To arm the lock again, we just have to reverse the disarming process:
- The slip is placed with its corresponding springs.
- The combinations are installed in the reverse order of disassembly, without forgetting that after locating the first two, the safety pin is placed in the closed position.
- The binding lever is placed, which is the one that allows the lock to be operated with the key.
- The cover is put on and screwed on to test the lock before installing.
- If everything works fine, proceed to install the lock again on the door.
