Do I need to install another entrance door inside the security door?

Panpan anti-theft door itself has the functions of sound insulation, fire and heat preservation. The developer did not install the cat's eye because they were not too careful when they made it again, and the general security door has a cat's eye, and it is included in the door by the manufacturer. Now that it's installed, I'm thinking about installing a cat's eye separately, I'm afraid it's not good.

You look for someone who sells security door keychains nearby and ask if you can help. With a bright Zen cat's eye, it's not worth much stupid dust and less money. The main thing is the opening hole.

No need to install another door! Just wrap a door sleeve inside the door frame....If you need a cat's eye on the door, you can ask your decoration master to help you make a hole in the door, buy a cat's eye and install it.

This is not needed, because once the entrance door is removed, it will leave the door frame, and some elderly people or children will fall.

In this way, you can ask the store, can you change the anti-theft door, it is still not recommended to install the door into the door, double unlocking or something is very troublesome.
