Preface: My OP-1 has under 12 hours of usage. It still has plenty of time on the 1-year warranty.
I probably wouldn’t worry about it. Can we see a pic of how “out of level” it is all the same? It’s likely nothing major*
*i take no responsibility if your OP-1 bursts into flames or otherwise stops working when you prod the key and/or ignore it
I’ll upload a picture when I’m off work tonight. If this makes any sense: the un-depressed key in question rests flush with the frame of the OP-1 (whereas the rest of the keys are normal height – a couple cm’s above the frame of the unit).
Here’s a picture (it’s the leftmost keyboard key)…though you may be on to something about it being nothing. I noticed when taking the picture that other keys in the keybed are also not even with others. Who knows…
Maybe it’s not attached correctly. I had one like that (after I dropped it :O), I pressed it down firmly and evenly and it clicked back into place. The other option is to pop the key off and reseat it. They’re attached like old school computer keys.
I had this problem with my OP-1 when I received it.
One key felt a bit flappy and also looked to be below the height of the others.
I popped the key off and one of the parts where the little clip fitted on had broken on the key itself.
I sent a support ticket to TE and they send me a replacement key.
