Saint helena entrance code?

i just have started today and am trying to get into saint helena. " The key ring round the biggest rock. point west and catch the port we dock." I have put the ring of the key on every rock pointed west and tried everything that I can think of. it's most likely an easy answer but that's why I can not figure it out. any hints, info, or answers will be largely appreciated. thanks.

I think the word is count

try manmade

It's difficult, look for the word that is between the keys two prongs. It works.

It's a five letter word.
