Let's call the client Sergei. After returning home, he noticed fresh damage to the outside of the cylinder. The key worked. The door was opening. Therefore Sergey asked:
“Why change a working cylinder?”
Because the ability to turn a key is only one characteristic of a mechanism. The material provided recommends considering a replacement after a serious mechanical impact on the cylinder precisely because the internal elements can be weakened, even if the mechanism is still functioning.
What could have changed
Could be harmed:
- body;
- internal elements;
- fastening;
- cylinder geometry.
However, the standard key can still work.
Does this mean that any scratch should be considered a tampering attempt?
No. First you need to distinguish:
- normal household wear and tear;
- traces of a bunch of keys;
- damage to fittings;
- serious mechanical impact.
Why it's useful to take photos first
If the tracks look unusual, record:
- general view of the door;
- cylinder;
- fittings;
- area around the lock.
This is also useful for further technical assessment.
Do I need to change the entire lock?
Not necessarily. If the main body is faulty, the solution may only concern the cylinder or the protective fittings.
