Unlock a lock

Lock locked: here’s what to do

The causes of a lock locked they can be multiple.
In some cases with specific products it will be possible to solve the problem by yourself but in others, unfortunately, the only solution will be to call a specialized technician.

For example, especially if it comes to armored doors and inside the key has remained in the lock, the only solution would be to ask whoever is in the apartment to remove it. However, if there is no one on the other side, it will be necessary to call a technician who will drill the cylinder to be able to return home.

How to open a locked door: lubricate the lock

Over time it can happen that the door lock and jams and the key is no longer able to turn easily.

In most cases, however, the lock will not be broken and will simply be enough lubricate it to make it look like new again.

The main cause may be the dirt. Especially modern keys have in many cases forellini which could accumulate dust and residues of all kinds.

When this happens the key will struggle to both enter and rotate.

Door blocked to lubricate: what products to use

The most wrong is to use oil or natural lubricants but unfortunately it remains a very common practice.

These products, in fact, will attract the dust in addition to leaving many residues and the key will make it even harder to work. The products to use instead will be:

  • WD- 40;
  • graphite powder.

The former is one of the best lock lubricants on the market.
It will simply be necessary spray the product inside the lock, then on the key and finally, insert it two or three times into the keyhole.

If the key still does not fit properly, spray a little more product into the lock.

Do a lot attention not to use too much of it all together because it could come out of the lock and dirty the door.

The graphite powder represents the alternative solution, the material of which the tips of the pencils are made. This product adheres to metal, without greasing the surfaces.

Also in this case it will be necessary to put it in the locked lock and insert the key two or three times.

The new generation keys have small holes that could get dirty over time
You can also try switching the tip initially a pencil on the key.
If the problem is not serious, this simple step should suffice.

The graphite powder you can buy it safely in any tool or on Amazon.

How to open a stuck lock: broken key

It may happen that one key breaks inside the lock cylinder but, before calling a technician and spending money, you can try a simple solution, and above all for free.

You will need to get a crochet iron, those normally used to make lace, taking care to choose one very small measuring 0.75 or at most 1.
Much will depend on the type of lock you are dealing with.

With the hooked part of a small crochet hook it will be possible to remove a broken key
Then insert the iron in the lower part of the cylinder where there are the teeth of the key. Just try to grab one of them and, gently, pull out the broken piece that blocks the lock.

If it makes too much resistance it is recommended to use the WD-40, or what Svitol to facilitate the operation, by spraying a little product into the patch.

How to open a lock if the cylinder is stuck

Undoubtedly, this is the worst case. If the cylinder has been forced or is simply very old, it may have suffered damage, which no longer allows it to open due to a mechanics now compromised.

In this case theonly solution, especially if you are facing a security door, will be the one to call a specialized technician who will have to drill the cylinder, remove it and install a new one.

The causes of this damage can be essentially two.

The first is for an attempt break-in; the second could be due to excessive humidity which in the long run could cause rust to form which will affect the mechanics of the lock.

The key and the lock: maintenance

A good way to prevent the lock from getting stuck will be to remember from time to time to make a good one maintenance.

The locks don’t lock overnight but they will give clear signs of impatience even before.

In particular, the first sign is represented by a mechanics no more perfect than the scrocco which could, at times, get stuck. The operation to be done is simple. It will be necessary to have Svitol, lubricating the latch at best.

Same goes for what concerns the bolt (photo below).

Finally, make sure that they are not present on the key residues of dirt The game of sweaters or jackets because they could accumulate in the middle of the lock mechanisms, making even the best lubricant useless.
