Bests & Worsts Reviews from Amazon

I ordered 2 sets of 4 locks at 2 different occasions. According to the products details 4 locks in the set are keyed alike but the second set of 4 locks is also keyed exactly same as the first set. This is not what I expected. I was expecting the 4 locks in 1st set to be keyed alike and 4 locks in the second set to be keyed alike but Keys for set 1 and 2 would be different but all 8 have the same keys!!! Makes me wonder how many same keys and locks they have distributed to others. All my 8 locks have code as 702 even though 4 orange ones were ordered later.
