I agree with 3rd post in this thread. I did it same way using coinomi.
In simple steps:
1 - Get rid of the BTC on given address ( this just to be sure when something goes wrong you are going to lose only BCH) by sending them to some your other wallets.
2 - Export the privatekey ( from the NOW empty address)
3 - Import the private key to any BCH supporting wallet (like coinomi)

The above mentioned address has no BCH on it. Why are you importing it? From what I have read you should be importing the bitkee address ( which IMO has the BCH ).

EDIT. Sorry, just notice the addy has BCH. (I have copied it with the watch at the end).
So is seems your only problem is how to extract the privetkey from bitkee. Their FAQ should help.
