What is the labor key?
The first question we need to answer is what is the labor key? In order to correctly answer this question, we must first determine what anti-theft doors are. Anti-theft doors are a type of building doors that bring a lot of safety to the environment and are of very good quality in every respect.
Now you should know that these doors, when they are made, have two sets of keys. One of them is the main key and will belong to the owner of the building. Other types of keys are also used when workers are still present in the building and are busy with construction.
These keys are called worker keys Security door and will be in the hands of the workers or the janitor.
The thing you need to know is that the master key and worker key both belong to a specific door and after the house is completed, the master key is used and the worker key is removed.
A point that is very important and should be taken into account is that during the construction of a house, many people move inside the building and there is a need for a key. On the other hand, expensive items in the house cannot be left to the safekeeping of God, and that is why the door of the house must always be locked.
This is where the importance of having a spare key or working key comes into play. Actually, after the building is completely built, the master key will be handed over to the house owner. The point here is that after the delivery of the main key, there is no longer a need for a worker's key, and that is why it must either be destroyed or handed over to the home owner.
Therefore, the main use of Security door worker key is to use it during construction.

How many keys do anti-theft doors have?

But if we want to make a general count, we should say that the keys of Security door are generally seven or eight. The type of these keys are also computerized and that is why a lot of precision is used in their construction.
The lock system and the tabs of the theft door are such that if you put the key inside and turn it, all eight tabs inside the lock enter the Security door frame in a fixed and non-fixed form from both sides.
If you have brief information about anti-theft doors, then you know that these doors are manufactured in three countries:
Türkiye, China and Iran!
If you buy Security door cracks you will notice that they have eight keys. Three of these keys are used by workers during the construction process and are considered as labor keys. But the rest of the keys belong to the original owner of the structure and will be given to him when the building reaches the final stage of use. A very important point here is that the main keys should not be used at the same time as the working key.
But Chinese anti-theft doors are also supplied with seven keys. Among these seven keys, two of them are provided to the workers and are used for their commuting. These two keys are the only keys that will be used until the building is in operation. But when the building is completed and it's time for the owner to take over his unit, all five keys plus the remaining two keys must be handed over to the owner. Because there will be no need for workers' keys anymore and there is no reason for them to come and go to the building.
The important thing to know is that when the main keys are used, the worker keys will be disabled and can no longer be used.

How to secure Security door from thieves?
As we mentioned, anti-theft doors are one of the main elements of home security. Although anti-theft doors can usually significantly protect the safety of the house, sometimes, the occurrence of a series of problems makes it possible for thieves to find a way into the house.
But there are some simple solutions to prevent this from happening:
- The first way, which is very simple, is to change the door lock nut. Especially if the house you bought has had owners before you.
