Long key not working

Long key not working
I inserted the long key to separate the comb to let the honey drain out
It isslipping I only have one key

Insert the key 1/4 of the way and turn then another 1/4 - until the whole lot are open.

First time may be stiff

Does what Valli has explained make sense Don? If not then you might need to be more explicit, depending on the amount of wax and temperature, turning the key can be tight, I found that a few inches at a time helps.
