How does a door lock work

How an electronic lock works simply explained

When you leave the house in the morning and go to work by bike or car, you usually have two to three locks open. We come across locks very often in everyday life and understanding how they work is also very easy. But how does an electronic lock work? Only very few people then have the knowledge, even though we use the electronic lock almost every day. Be it to unlock the car, to come through a revolving door in the swimming pool or to open a locker. In the following we would like to tell you from Molten metal bring this functionality a little closer. We do this by showing you the different types of electronic locks, how they work in detail and also name a few advantages.

There are basically four different types of electronic lock. These are the most common and you have already come across most of them in your everyday life.

The code lock as an electronic lock

Everyone should have come across the code lock at some point. This principle is often used with safes or Gun cabinets used. The principle behind it is also very easy to understand. The code lock is provided in advance with a pin belonging to the owner and to open it, all you have to do is enter the set pin. Input is either digital or physical buttons. A signal is sent by radio to the receiver, which in turn checks whether the signals match the set pin. If this is the case, the electronic lock will open. The physical variant in the form of a Padlock is similarly safe.

Open the electronic door lock via RFID

First of all, RFID is used for radio-frequency identification, i.e. identification using electromagnetic waves. The authorized person must identify himself using a coded chip that is built into a transponder. The transponder is a radio communication device and is as small and handy as a car key. The transponder can have different designs, depending on the manufacturer. This can come in the form of a key, card or bracelet. To unlock, hold the transponder on a calibrated receiver, which determines the radio frequency. If the user data matches the database, the door or something similar opens. The particularly nice thing about this electronic door opener is that, as an administrator, you can also set times in which an authorized person can gain access. For example, the babysitter could receive a transponder and thus gain access in the times, for example from 1:00 p.m. to 5:00 p.m. daily. In practice, this type of electronic lock is often found in swimming pools, for example. This technology is used here to ensure that the guest receives entry and the bathroom can determine the exact time that the guest spent in the bathroom in order to determine the entry price.

Open the electronic lock using a smartphone!

Digitization continues to advance and of course does not stop at locks. All you need is an electronic locking cylinder with a corresponding attachment and an app. The mobile phone and the locking cylinder then connect via Bluetooth. As soon as you come near the electronic lock, the door opens as if by magic. The smartphone does not even have to be unlocked for this, but it must be switched on and able to connect to Bluetooth. However, you can usually change the settings here to suit you best.

With this form of the electronic lock, guest accounts can also be created, which can be defined in terms of time so that babysitters or cleaning staff only have access at certain times.

Chip cards: inexpensive alternative to the electronic lock compared to the RIFD

Have you been to a hotel in the past few years? For most of them, the answer is likely to be positive. Every hotel guest has certainly already received a chip card to open their room. But how exactly does this electronic lock work? As soon as the user holds the card up to the corresponding reader, the data is compared with that of the database. So a similar system to the RFID principle. The advantage here is, on the one hand, the lower costs and the ease of use for the administrator if a guest's card is lost. This can quickly delete or change the data in the system.

We hope we were able to give a little overview of the individual functions of the classic electronic locks with this overview.
