Can the entrance door of high-rise new house be replaced? How should I replace it?

I suggest you look at the quality of the door first and check the brand. If the quality is ok, you can use it directly. There is no need to spend more money to buy a door for a lock cylinder. If the entrance door is really bad, then change it decisively. After all, the entrance door is better, and you can't follow the requirements of the bedroom door. Under normal circumstances, it is necessary to give the builder a key when decorating, so most owners will replace the lock cylinder after decorating. However, the current security locks belong to ABC keys. The A key is specially provided for decoration. You can use the AB key when decorating. After renovation, the C key is put in the keyhole for a week, and the A key cannot be used.

Most of the doors provided by developers are entrance doors, that is, they can't meet the standards of security doors. The thickness of steel plate, lock core grade and built-in filler are far below the minimum standards of national standards for security doors. Engineering doors are installed only to meet the acceptance criteria. It is such a sign that there will be a permanent nameplate, which will indicate important parameters such as the manufacturer of the door and the fire rating of the door. Nowadays, many people change doors directly after renovation, and many fire doors are replaced by ordinary security doors, which only have anti-theft function and lose fire prevention function. Once a fire breaks out, it can't effectively resist the spread of the fire, and it can't win the time for people to evacuate safely, which causes great security risks.

Look at the sign by the door. There are four grades: A, B, C and D, and A is the best! The thickness of the door, locks and so on are different! Now the doors given by developers are basically ok! Look at your quality requirements. If you want to change it, I suggest you have an A-class door, and it is best to change the lock into a smart lock! First of all, it must be clear that the quality of this door given to us by the developer for free is not so impressive. However, it is not so bad as to be unacceptable. Generally speaking, if the developer's house can pass the "quality inspection" of the relevant departments, it is enough to show that it is up to standard. So we can keep it, and it also has basic functions such as fire prevention and theft prevention.
