What's the difference between how to open the door with a key when changing the password?

The difference between changing the password door and opening the door with a key is mainly reflected in the following aspects:

1. security: the password-changing door adopts a password lock, and the door lock can only be opened if the correct password is entered. In contrast, using a key to open a door requires the right key to unlock it. From the security point of view, password lock is more secure than key, because the password can be changed regularly, it is difficult to crack, and the key may be copied or lost.

2. Convenience: you can directly open the password change door by entering the password, without carrying extra items (such as keys). This is more convenient for residents and saves the trouble of bringing keys. On the contrary, opening the door with a key requires carrying the key with you, which is easy to lose or forget.

3. Applicability: The password lock can be set with different passwords, which is convenient for changing the passwords when necessary. This is very convenient for places (such as hotels or apartments) that often need to change the door lock password. In contrast, opening the door with a key cannot achieve similar flexibility, and the lock core needs to be replaced to update the door lock.

Generally speaking, the password-changing door is suitable for places with high security and flexibility requirements, while opening the door with a key is more suitable for places with relatively low security requirements. Which way to open the door depends on the actual demand.
