What should the master do after the door is already open

The client's name has been changed.

Let's call the client Martin. After the emergency opening, the master reported:

"Done."

The door actually opened. But Martin still has a few questions: *does anything need to be changed?

• why did this happen;
• is it possible to close the door again;
• will it jam in the evening;

A good emergency service doesn't always have to end the second the door opens.

First question: why did the malfunction occur?

If the door was simply slammed shut, there may not be a separate fault at all. But if:

• the correct key stopped working;
• the mechanism is jammed;
• the key is broken;
• the cylinder turned;
• the crossbars did not move,

It is advisable to understand the reason.

Second question: can I continue to use the lock?

If the mechanism is truly damaged, re-closing the door with it immediately after opening it may not be a good idea. Otherwise, after a few hours, the client may receive the same emergency situation a second time.

Third question: what needs to be repaired

Various options are possible:

• Nothing;
• door adjustment;
• service;
• new key;
• cylinder replacement;
• repair or replacement of the lock body.

Not every call has to result in the sale of a new piece of gear.

Fourth question: what signs to monitor

If the lock remains in use for now, it is useful for the client to know what to pay attention to:

• increase in effort;
• sound change;
• key stuck;
• backlash;
• the need to press the door.

Good result of emergency work

Ideally, the client receives three things: access restored; system status is clear; further actions are determined. The source material associates professional work not only with restoring access, but also with damage minimization and additional repair, replacement and consultation services.
