Accessing my wallet no keys

How do I get in to my wallet where all the keys were kept ?

ok so we moved house and had person stuff to deal with

I can log in to steemit with the password but all my keys were in the wallet now I can't access the wallet because its changed
I do not hold the posting key as it was in the wallet so how do we retrieve this as it was in the original wallet which is now needs the posting key to access a wallet ?
