Let's call the client Roman. After the repair, the master inserted the key, opened the lock once and said:
“Everything is ready.”
Roman thought:
“How do you know that the problem has really been fixed and not just a one-time fluke?”
This is a reasonable question. In the material provided, functionality testing is highlighted as a separate stage after repair: first, the malfunction is identified, repairs are performed, and then the mechanism is tested.
What it is advisable to check
Minimum:
- opening;
- closing;
- several cycles in a row;
- all used keys;
- work with the door open;
- work with the door closed.
Why open and closed doors are important separately
With the door open, the mechanism itself is mainly checked. When closed, interaction with:
- box;
- mate;
- position of the door leaf.
If the difference is huge, the problem may not be just inside the lock.
Why re-checking is useful
Some malfunctions do not appear with every movement. For example:
- periodic jamming;
- pen return;
- second turn;
- extracting the key.
One successful turnaround will not show this.
What to ask after repair
It is useful to clarify:
“What exactly was faulty and is it now possible to close the door normally?”
The client must understand the result, and not just see the mechanism that opens.
