Let's call the client Victor. Every summer, the lock on his outside door worked fine. In the fall, little resistance emerged. In winter, the key began to turn much harder.
In the spring the problem almost disappeared again. Victor asked:
“If everything is fine in the summer, does that mean the lock is still working?”
Not necessarily. In the materials provided, moisture, corrosion and temperature changes are directly named as factors affecting the condition of exterior and car locks.
Why temperature can change the behavior of a mechanism
The lock is affected by several factors at once:
- moisture;
- condensate;
- freezing;
- pollution;
- change in the size of elements due to temperature changes.
If the mechanism is already dirty or worn out, the problem can become much more noticeable in winter.
Why does the symptom disappear in summer?
Increasing the temperature may temporarily reduce the effects of moisture or freezing. But this does not mean that the reason has completely disappeared.
When seasonality is especially significant
If the problem persists: about the same every winter, this is already a pattern. Useful to check:
- cylinder condition;
- protection from precipitation;
- presence of corrosion;
- position of the door itself.
Do I need to change the lock right away?
No. First you need to determine what exactly reacts to temperature. Sometimes the problem is in:
- cylinder;
- doors;
- response part;
- another element of the system.
