Let's call the client Ilya. A high-quality lock was installed on the door, which worked without problems for many years. One day the mechanism suddenly jammed.
A question has arisen:
“How could an expensive lock even break?”
Because reliable does not mean eternal.
Any mechanical mechanism wears out
Working inside:
- springs;
- levers;
- drives;
- crossbars;
- other moving parts.
Over time, one element may fail.
Why the history of previous repairs is important
If the lock is already:
- disassembled;
- repaired;
- subjected to emergency opening,
This should be reported to the master. Previous intervention may influence today's fault.
Is there a fixed period of prophylaxis?
There is no universal rule like:
“cheap to replace every 5 years, expensive to maintain every 10.”
This statement from the original article is too categorical. You need to focus on:
- intensity of operation;
- state;
- behavior change;
- manufacturer's recommendations.
What symptoms should you notice in advance?
- new resistance;
- extraneous sounds;
- incomplete travel of crossbars;
- periodic jamming.
