Reliable protection of your front door starts with the right choice of locking mechanism. The secret cylinder is the heart of every lock – an invisible but crucial component that ensures that your door is unlocked only by you. A well-chosen cylinder provides peace of mind, long-lasting use and effective protection, regardless of whether it is a home, office or other type of premises.
Types of secret cartridges
Secret cylinders are available in different versions according to the level of security, the method of use and the compatibility with the door and the lock. Standard models are widely used on entrance and interior doors. Some versions have an internal handle (knob), which facilitates locking from the inside - without the need for a key. Others are designed with more compact dimensions for specific applications. An essential factor for choosing a secret cylinder is the standard - DIN or BDS. The secret cylinders offered by VALERIY are under DIN standard.
Choosing the right cylinder depends on several key factors – size (58/63 /68/80/90 mm), material (brass or coated metal alloy), number of keys and expected resistance to burglary attempts. For interior doors, simpler models are often used, while for exterior doors, high-security secret cylinders made of brass and with reinforced construction are recommended.

Frequently Asked Questions (FAQ)
How do I choose the right size of a security cartridge?
Measure the distance from the center of the mounting screw to the edges of the door on both sides – this will give you the exact values (e.g. 30/30, 35/45 mm, etc.) to consider when purchasing.
Does it matter what standard the lock is – BDS or DIN – when choosing a security cylinder?
Yes, the lock standard is essential for installation compatibility. BDS and DIN differ in the distance between the mounting screw and the faceplate, as well as the direction of insertion of the cylinder. To avoid mismatches, it is a good idea to check the type of your lock and choose a cylinder that meets the relevant standard.
Can I change a security cartridge myself?
In most cases, yes. Replacement usually requires only a screwdriver and a few basic steps: loosen the mounting screw, turn the key slightly, pull out the old cylinder, and insert the new one. However, if you are unsure of compatibility or do not want to take any risks with the installation, it is wise to contact a qualified locksmith.
