ok i just sealed the key hole in hollow bastion so now what do i do?

um do you mean when that card floats into the air and opens another gate way?

there are 3 keyholes that have to be sealed in hallowbastion but 2 in each world but i think 2 . so when ur done with hallow then go to another world and i think u might have to defeat another heartless
