i also have the big house i needd to change all the locks or replace all locks with a new one but i m not sure or trust worthy with any locksmiths cz i can never leave the house on them as i used to be in office but once my colegue told me about the same problem wen he used to replace his house locks and he was so satisfied with them change locks try them and now im satisfied as well they really take good care of privacy and security. so i sugest you to take help from them in changing locks and making new keys.
