The one you are talking about is not a hidden lock, the hidden lock refers to what cannot be seen from the outside of the house, if it can be seen from the outside of the house, then this can only be regarded as another lock on your door. If you want to add such a lock, you will need to break the door to install it or remove the original lock. In the past two years, I have known a kind of lock, an intelligent invisible anti-theft lock, which is a hidden lock.
The chain mail invisible intelligent anti-theft lock has been certified by the national public security authority, and the original lock does not have to be disassembled, and the installation is convenient and fast. It only takes ten minutes to install it yourself, press the lock body to lock the nose after the adhesive is installed correctly, and the screws on the lock nose can be reinforced. The lock body has two independent systems, even if there is a failure, the lock can be opened, the lock body will prompt when the battery is low, and the lock body will show the unlocking state when the power is out.
The key is a remote fob, which uses a rolling code, and each set of codes can only be used once, so you don't have to worry about thieves stealing the code to unlock the lock.
