Why a modern lock may also stop working one day

The client's name has been changed.

Let's call the client Renata. A few years ago he installed a modern, expensive lock. The mechanism worked well, so Renat practically stopped paying attention to it.

One day the key began to turn noticeably harder. First reaction:

“It’s modern and high quality. Why was there a problem in the first place?”

Because even a good mechanism remains a mechanical device.

"Reliable" does not mean "eternal"

Over time, performance may be affected by:

• wear;
• pollution;
• key status;
• door position;
• load on crossbars;
• incorrect operation.

Therefore, the quality of the lock reduces the likelihood of problems, but does not eliminate the need to monitor symptoms.

Which symptoms are best not to ignore?

For example:

• the key began to work harder;
• there was a need to rock it;
• the lock began to make a new sound;
• the second revolution became more difficult than the first;
• the door has to be pressed;
• the cylinder began to move.

This is not always a serious problem. But this is a change from the usual work.

Why you shouldn't wait for complete failure

While the door is opening, the specialist can:

• check the mechanism;
• compare work with the door open and closed;
• assess the condition of the key;
• understand whether the problem is related to the adjustment.

When the door no longer opens, the task automatically becomes an emergency.

Is it necessary to change a modern lock at the first symptom

No. First a diagnosis is required. Sometimes it turns out that the problem is not in the lock at all, but in the position of the door leaf.
