Digital locking systems / locking cylinders
What is behind the term locking cylinder?
As soon as it comes to securing private homes, companies or public facilities, you can't get around them: the locking cylinder!
A locking cylinder describes different cylinder types and cylinder technologies. Locking cylinders are available in different sizes, shapes and materials. Depending on the design and use, the look can be round, oval or profiled. The respective naming is also structured accordingly: „round cylinder“, "oval cylinder“ or „profile cylinder“.
Modern and convenient locking cylinders are often equipped with an emergency and danger function which enables doors to be opened, even if a key is inserted on the other side.
Components of a locking cylinder
A locking cylinder essentially consists of the following components:
- Cylinder housing
- Cylinder core
- Pin springs
- Plug and housing pins
- Hole for the fastening screw
Mechanical locking cylinder - How it works
Basically, the function of a cylinder is simple: The identification medium (e.g. key, transponder or keycard) contains coding. If the coding matches the cylinder core, the locking cylinder can be locked.
As previously mentioned, the basis of a cylinder is the cylinder body ("stator"). This housing contains the cylinder core ("Rotor"), which can be rotated. This cylinder core has the holder for a key. The plug only moves if the appropriate key has been inserted correctly. Image tag: Locking cylinder Image tag: "Electronic locking cylinder" Keys and locking cylinders have a so-called "cam". This person is responsible for ensuring that the bolt is transported in the lock. It serves as a transfer part, so to speak.
Locking cylinders - Types
A distinction is made between different locking cylinder types depending on the area of application and requirements:
A double cylinder is most commonly used. This model offers the possibility to close from both sides. There are mordern double cylinder variants which also enable opening if a key is inserted in the key channel on the other side. The double cylinder is often also known as a "profile cylinder".
Application areas: Entrance doors, apartment entrance doors, basement doors, room doors
A knob cylinder offers the option of locking from only one side using a key (usually from the outside). There is a knob on the opposite side. This enables the door to be closed from the inside at any time. Important: A knob cylinder is not suitable for use in glass doors.
Application areas: Entrance doors, apartment entrance doors, basement doors
Half cylinders also only lock from the outside. Inside, the half cylinder is always 10 mm long. On the outside, the length can be extended variably depending on the application.
Application areas: Basement doors, garage doors or key boxes
The lever cylinder opens with a rotating locking lever. The lever is attached to the rear of the cylinder and exists in various variants.
Application areas: Mail boxes, safe deposit boxes, lockers, vending machines, lockers, light flaps
The outer cylinder is used for use in rim locks and additional locks. These are screwed to the inside of the respective door. By turning the key, a metal tongue activates the cylinder lock.
Application areas: Garage doors, cabinet locks, additional locks
A special locking cylinder is the padlock. The padlock, also known as a padlock or padlock, is often used for theft protection. The compact U-locks often secure valuables or smaller rooms with a chain or bolt.
Application areas: Bicycle lock, basement doors, attic doors, garden doors, gates
Another unusual candidate is the dummy cylinder. Doors that are not to be locked or locked can be equipped with dummy cylinders. This conceals the cylinder opening of the door, which prevents smoke from seeping through in the event of a fire, for example.
Application areas: Doors without locking function, fire doors that should not be locked
Locking cylinder – keyed alike and individually locking
In addition to the aforementioned types, a distinction is still made between cylinders which lock at the same time and cylinders which lock at the same time.
With the simultaneously locking or simultaneously locking variant, it is possible to lock several locks with a single key set. This variant is often used in apartments so that the house door, apartment door, basement door, garage door and attic can be opened and closed with a single key.
A locking cylinder with an individual lock can only be locked with a key which has been manufactured to fit the respective cylinder. The key of this cylinder does not actually fit any other cylinder. Lockable handles of the patio door and balcony door, for example, are closed separately by means of a single lock.
Limits of conventional locking cylinders
The large number of variants and areas of application of locking cylinders offer different options when it comes to securing people, objects and buildings. However, these different combinations are also the greatest weakness:
The house entrance door and apartment entrance door ideally close with the same key. Terrace door and balcony, however, with different variants. The padlock for the basement and garage also requires additional locking cylinders or keys. If company or association keys are added, the bunch of keys comprises almost a dozen keys. Hardly to think about the enormous cost and time involved in losing the key ring.
Another disadvantage is the lack of ability to map hierarchies. It is almost impossible to depict different locking levels using conventional mechanical locking cylinders. Especially for companies or public institutions that have to issue hundreds of keys.
The solution: an electronic locking cylinder
In the past, mechanical locking systems were generally installed to secure buildings. However, the design and use of these systems had to be well thought out and planned very precisely. Depending on the person group and organisational structure of the building, the effort behind the planning could not be underestimated, especially when it came to mapping access authorisations. The expansion of buildings faced an even greater challenge when conventional mechanical locking cylinders were used.
Fortunately, today, this concern is a thing of the past. Electronic locking cylinders offer completely new possibilities when it comes to securing buildings. These locking cylinders work hand in hand with electronic or digital locking systems and, in addition to security, offer enormous convenience.
Pioneering electronic locking cylinders and digital locking systems
Key missing? No problem! Thanks to modern identification media such as transponders or smart cards, the digital key can be immediately blocked and replaced. Building security is restored with just a few clicks.
Representation of different groups of people with access to predefined areas? Electronic locking systems provide a remedy! The convenient creation of complex access authorisations gives employees, guests or suppliers access to predefined areas. This access can also be limited in time.
Do you want to expand a building complex? Digital locking systems can be extended! Electronic locking cylinders and associated identification media can be added as required. Modern locking cylinders are completely integrated wirelessly into new parts of the building. Previous transponders can be conveniently activated for the new building complex within just a few seconds.
Other advantages of digital locking systems with electronic locking cylinders
Digital locking systems offer the highest level of security. Thanks to digital locking cylinders and an identification medium, buildings with the highest security level can be equipped. Unauthorised penetration is usually prevented even in the event of external force, as the cylinder is also mechanically secured.
Doors are opened with future-oriented identification media. This means that digital locking systems use an RFID medium which replaces the conventional key. Doors are opened conveniently and contactlessly.
Should people be grouped so that only certain areas are accessible? No problem – access authorisations can be individually configured and controlled with digital locking systems. You can reprogram existing authorisations with just a few clicks without having to exchange the access medium.
Electronic locking systems can be extended as required. Connection to other digital systems and systems is possible without any problems. For example, a fire alarm control panel or alarm system can be connected, which triggers directly in the event of danger.
If a key is lost in conventional mechanical systems, all cylinders must be replaced and new key sets handed out. These costs can quickly be in the five-digit range for a multi-party house or large employee base. If the identification medium of a digital locking system is lost, the medium can be easily blocked and replaced so that the security of the building is immediately restored.
