The electronic lock is a door locking mechanism familiar to us, but having an electronic functionality for specific functions. In fact, such devices have existed for quite some time, for example, one of their types – an electromagnetic lock – is probably still installed on your intercom door. However, we will not be interested in magnetic locks, since they are entirely unsuitable for home doors (in the absence of external power supply, they open).
Another thing – electromechanical lock. Such a device is based on the usual steel bolt (locking unit), which is triggered when the necessary signal is sent from the control module. That is, here we are dealing with reliable mechanics that will calm our nerves and keep the apartments, and with electronic functions that will make life more convenient.
“But the electromechanical lock also needs power!” – You will say. True, but self-contained batteries installed in the device solves the issue. This makes the lock independent from the external power supply as well as from power outages and power surges. The digital door lock just works for itself – just like its mechanical counterparts. Usually, the batteries last for a year of work, and so that they do not suddenly sit down, electronic locks notify the owner about the early discharge by indication, sound signals and even notifications to the smartphone.
So, with the security, we half figured out – now move on to the most interesting.
Why is this convenient?
Science fiction starts from the moment we open the electronic lock. The fact is that such devices not only allow you to do this quickly and conveniently but also, as a rule, make it possible to choose the principle of action.
The most straightforward technology to open an electronic lock is a dial code. We approach the door, we dial a digital password on the touch panel, we have set it in advance, and the door opens. This is convenient in the first place because you can forget about the problem of keys forever, or at least not be afraid to forget them at home. You returned from work, and there were no keys in the bag- it doesn’t matter: we type the password.
The second method is an electronic key or RFID card. Attached such an element to the lock- the door is open. In this case, as before, you need to carry the keys (map) with you- but there is no need to mess around with the keyhole. With bags, whether we are from a store, with a dog, whether on a leash or with poor coordination of movements after a party- the door opens instantly.

All these methods are often present in the castle all at once, and the user is free not only to choose which one to use but also to combine them at his own discretion. For example, you can program a lock to open after entering a digital code and applying for an RFID card. Or after activating the function on the smartphone and triggering the fingerprint sensor. Combinations make electronic locks the safest of all that exists: even if the robber takes possession of the key, he will not be able to open the door. And vice versa: having learned the code, he will also need the key.
The third way is a smartphone, and here we are approaching, finally, to call the lock “smart.” From the point of view of opening the door, the method practically does not differ from the previous one; however, synchronization with the smartphone gives several exciting bonuses.
