What is better in case of emergency opening: keep the lock or open the door as quickly as possible?

Let's call the client Denis. The lock of his apartment stopped opening. The first wish was simple:
“The main thing is to open it. If necessary, break it."
But after access was restored, it would turn out that damage to the door could cost much more than the lock itself. Therefore, a good emergency technician evaluates not only the speed, but also the overall damage.
In the source material, a careful opening is contrasted with a destructive one precisely because of its consequences: the opportunity to preserve the mechanism and avoid additional damage to the door.
What does "minimal intervention" mean?
This is not a promise to save absolutely everything. The priority might look like this: 1. save the door leaf; 2. save expensive fittings; 3. maintain serviceable lock elements; 4. Replace only what is really damaged.
Sometimes it is possible to preserve the mechanism itself. Sometimes there is no point in keeping a faulty cylinder.
Why you can’t promise in advance “without a single scratch”
Unknown before inspection:
- what is broken;
- in what position is the mechanism;
- were there any independent attempts;
- what is inside the lock.
Therefore, it is more correct to promise the desire for minimal intervention, rather than an absolute result blindly.
When destructive intervention may be justified
For example, if the faulty element: *cannot be restored.
- already destroyed;
- completely blocked;
But even then, you need to choose the option that will least affect the rest of the door.
Why a cheap lock should not be saved at the cost of an expensive door
Let's say:
- the cylinder costs relatively little;
- door leaf and fittings are significantly more expensive.
In such a situation, the priority is obvious.
