What is the role of the door insert?

The door insert is the part of the door into which the key is inserted. For this reason, it has a function that is not only aesthetic, but above all security. A properly selected and well-installed insert will be difficult to ream or pull out, thus preventing a possible break-in. That's why, although the cylinder seems like a small and simple component of the door, its selection is extremely important.

A quality lock cylinder will be durable if the materials used in its manufacture are also so. To make our customers feel even safer, the inserts use additional safety features, such as anti-drill pins, steel reinforcements, pledges or an anti-bumping system.

Door lock cylinder - how to choose it?

It is impossible to select a good door lock cylinder without downloading exact measurements. However, it is so simple that after reading a few tips you will certainly manage it - even if you are doing it for the first time.

To measure the length of an insole properly, you just need a screwdriver and a tape measure. The measurement must be extremely precise, so we do not recommend measuring an insert placed in the door. In this way, you can make a mistake by millimeters, which will be important for the security of the house or apartment. For this reason, the lock cylinder should be unscrewed beforehand.

The lock cylinder should have two dimensions: the first determines the distance of the axis of the bolt hole of the cylinder (the axis of the picker) to its outer end, and the second determines the distance of the axis of the bolt hole of the cylinder (the axis of the picker) to the inner end. Keep in mind that the insert should neither be hidden in the door sign nor protrude too much. It is assumed that optimally the insert can protrude up to 2-3 mm beyond the sign. If it is longer, it will become easy to break.

Door lock cylinders and their types.

The most common type of door lock cylinder is the cylinder. This type of cylinder works in close cooperation with mortise locks, interacting with each other. To open the door with this type of cylinder, flat keys are suitable. They can have notches (the more of them, the more difficult it will be for unwanted people to open the cylinder) or be drilled (they have a few to dozens of holes and are considered more secure than notched keys).

In the offer of the Sparta store we also have patent cylinders and lock cylinders with additional certification according to specific standards. Some of the cylinders in our offer (such as Husar S8, Abus D10, Winkhaus Ntr, CES PSM) also have a special security card. This means that making an additional set of keys is possible in selected certified points, only upon presentation of this particular card.

Door cylinder - how to take care of it so that it serves a long time?

Like any heavily used item, the door cylinder also requires proper handling so as not to damage it too quickly. While this topic may seem trivial, all you need to do is develop a few simple habits so that your door insert will serve you for many years.

What you can do.

• don't use the key as a handle - some people put the key in the cylinder and, pulling it, open the door. So try to remember that from opening the door there is only the handle,


• insert the key to the end - not halfway into the lock, nor ?almost to the end?, but to the complete end, i.e. until you feel resistance,


• never use a damaged key - such as a chipped or bent one. Likewise, never put objects in the lock that are not a key (e.g., hair pins) and try to open it that way,


• do not force the lock - that is, do not turn the key by force. If you encounter resistance, it is worth finding and eliminating the cause of this as soon as possible,


• use lubricants - such treatment is enough to repeat several times a year, so that the cylinder serves as it should.


• take care of the cleanliness of the key - this applies mainly to drilled keys, in which over time dust and dirt accumulate, which can significantly hinder or prevent its rotation in the cylinder.

Single key system

In our offer you will also find cylinders suitable for the so-called one-key system. What is this system based on and is it a secure solution?

A single key system assumes that all cylinders in a given system can be opened with the same key. In this system, for example, patent cylinders work well (they can have different dimensions), which can be successfully combined with padlocks. As the ordering party, it is you who determines how many doors (inserts) will be included in one system.

The great advantage of this type of solution is security, because in an emergency situation you will open all the doors of an apartment, house or other building with just one key, without having to search for those to individual rooms. Also important is the already mentioned security card, thanks to which you can be sure that no unauthorized person will not make his copy of the key.

There's no denying that the single key system works great, especially in office buildings. It's also a huge cost-saver, which allows you to level out the number of different keys operating within the building. It allows you to replace a bunch of keys with a single key.

Master key system

Another interesting solution is the master key system, which is often confused with the single key system. However, the two systems share a basic difference: while a single key system is simply a combination of cylinders that can be opened with a single key, a master key system can be much more elaborate and complex. This is because an entire hierarchy of access to the various rooms of a facility is involved. Groups defined by the building manager have access to various sections of the building. In this way it is much easier to coordinate the work of, for example, cleaning companies or other external companies. Of course, such a system may include door inserts, furniture inserts, elevator activation inserts or padlocks. The largest systems in Europe number several thousand products and have been successfully operating for many years.
