Let's call the client Raivo. His lock worked well. The key turned normally. There were no mechanical problems. But upon inspection it turned out that the external protective fittings were chosen poorly.
Raivo was surprised:
“Why change anything if the lock itself works?”
Because serviceability and security are two different things.
What role does external fittings play?
She can:
- protect the cylinder;
- fix elements;
- block access to fasteners;
- form the correct position of the mechanism relative to the door surface.
Therefore, a good cylinder without suitable protection does not always work as a complete system.
Why compatibility is important
The fittings must comply with:
- door thickness;
- cylinder type;
- lock designs;
- installation method.
You can't judge just appearance.
Do I always need to change the old pad
No. If she:
- serviceable;
- correctly installed;
- corresponds to the system,
there may be no reason for replacement. The recommendation must have a specific technical reason.
When the question is especially relevant
For example:
- the cylinder protrudes strongly;
- the cover is loose;
- fasteners are loose;
- a new cylinder of a different size was installed;
- the door was previously redone.
