In most cases, cylinders are used wherever things need to be locked. Entrance doors, apartment doors, basement doors... You will encounter a locking cylinder regularly at these doors and will need the correct key to unlock the lock.
Definition of locking cylinder
The locking cylinder plays a central role in security. The key must fit, otherwise it cannot be unlocked. The much more common variant is still the mechanical locking cylinder. The key therefore has cuts and is thus equipped with a profile. This profile must fit into the locking cylinder so that the key can be inserted and the locking process can be carried out.
Not all locking cylinders are the same – a distinction must be made here. Different versions are used depending on the area of application, which are discussed in the following.
The classic: Profile cylinder
The most common and widely used locking cylinder is the profile cylinder, also known as a "double cylinder". "Double", as a key can be inserted and used here on both sides. This makes the cylinder very suitable for entrance doors in buildings.
The profile cylinder can also be equipped with a danger function on request. This means that it can lock from both sides, even if a key is already inserted on one side. This makes sense, among other things, if there is only access to one apartment, as this ensures that you can continue to unlock with another key if a key is inserted on the inside.
Which locking cylinders are also available?
In addition to the profile cylinder, there are also various other types of locking cylinders. This includes, for example, the thumb-turn cylinder. This can only be locked on one side with a key, on the other side (usually inside the room) a thumb-turn is used to actuate the cylinder. This means that it can always be closed from one side.
It is similar in half cylinders, except that there is also no thumb-turn here via which it is locked, since it can generally only be locked from one side. A special feature of this locking cylinder is that it basically has a length of 10 mm on the inside. It can often be found on garage doors or key boxes, for example.
A somewhat less secure locking cylinder, which is therefore not used on doors, is the lever cylinder. If you insert the key into the lock here, you can turn a lever to open the door. This simple locking mechanism is used, for example, on mail boxes and in lockers.
Also to be mentioned is the cam cylinder, which is often found on additional locks which are screwed on from the inside, for example on rim locks or garage doors.
Special case: the anti-panic cylinder
The so-called anti-panic cylinder must be mentioned separately for the locking cylinders. This locking cylinder is also called a panic lock and should of course not spread it, but act against it. He therefore has the name that he prefers to use it on escape routes.
The special feature of this locking cylinder is that it can only be opened and closed from one side, while it must be ensured that the door can be opened from the other side at any time. For this reason, it is used on escape routes, as in the event of a fire, for example, it must be ensured that it enables rapid escape.
Due to this special feature, a door with this locking cylinder is often fitted with a so-called panic bar instead of a door handle, which can be pressed down. This extends to the door handle height over the width of the door and is thus also automatically pressed if there is a push along an escape route.
A sensible alternative: the digital locking cylinder
Until now, we have mainly talked about mechanical locking cylinders, but there is one sensible alternative: the digital locking cylinder. Instead of a key, you receive a locking medium such as a transponder, which is programmable and can be equipped with the corresponding access authorisations. The advantage here is, among other things, that the key can be extended at any time with additional accesses (which can of course also be withdrawn at any time). Once programmed, other locking cylinders can also be opened with the locking medium.
If a "key“ is lost, it can simply be blocked in the digital locking system. This is also an advantage of the electronic locking system. In the event of a lost key, lock cylinders would have to be replaced in mechanical systems in order to maintain the locking system's security. With digital systems, this risk is eliminated.
