Tight Key??

[moy71]

On my piano,  I can physically raise the piano key by roughly 1/2 cm.  But in that short travel, there is a considerable tightness.  Once its up,  it will not return to its original position.  I need to push it back down to return to its normal state.

Is this normal?

Or is this a sign of humidity issues?

Aside from this,  there is no apparent sticky key issues when the piano is played.

Thanks for your time everyone.

Play it then. The only abnormal part is the instrument is being monkeyed with instead of used properly.

Find something important to worry about  because this isn’t it.
