Why you can’t constantly “get used” to a poorly working key

The client's name has been changed.

Let's call the client Marina. At first the key opened the door normally. Then I needed to move it a little. After some time, Marina already automatically knew:

“You need to insert the key, lift it up a little, then turn it.”

She got so used to this movement that she stopped perceiving it as a malfunction. The problem was discovered only when one day the usual method no longer helped.

Why a person quickly adapts to a malfunction

If the change occurs gradually, the user begins to consider it part of normal operation. For example:

• the key needs to be rocked a little;
• the door must be pressed;
• the handle needs to be raised;
• the second revolution is more difficult;
• the key must be reinserted several times.

But a working mechanism usually does not require special “rituals” for daily opening.

What could be happening

The reason may be:

• worn key;
• cylinder wear;
• door skew;
• internal wear of the lock;
• load on the crossbars.

Why this is important to notice in advance

The more the user compensates for the malfunction with his movements, the longer the real cause remains without diagnosis. As a result, a moment arises when no habitual movement helps.

What to do

Try answering a simple question:

“Does the door operate as easily today as it did a year ago?”

If not, it's helpful to understand why.
