If it's fitted with an articulated low C# key, the key barrel on the C# pad cup can bind between its set of pillars as it's a cross key which is more affected by humidity changes than a key running along the length of the joint (on a wooden bodied oboe).
Other cross mounted keys that can suffer are the lower (1st) 8ve pad cup, the forked F vent rocker and pad cup and the Eb pad cup as they're lightly sprung to open under their own spring tension (and are being held closed by a much heavier sprung key or piece of mechanism). So if the pillars pull in due to the joint diameter changing (due to the drop in humidity), these keys are prone to binding.
Best cause of action is to have the key barrels on these cross keys all shortened very slightly so they have a bit of play between their pillars, so they'll still work when humidity levels are low.
