Can the landlord come in with the Bluetooth door lock?

Yes. The landlord can use the mobile phone APP to authorize the Bluetooth door lock, so that he can directly unlock and enter the room through his mobile phone. The Bluetooth door lock sets an unlocking password, and the landlord can also use the password to unlock and enter the room. In order to ensure the safety and privacy of tenants, landlords need to abide by relevant laws, regulations and ethics when using Bluetooth door locks, and are not allowed to enter the room without authorization or abuse the unlocking authority.
