These key blanks are made for a heavy duty and high secuirty mailbox sold by big box retailers such as Lowes and Home Depot. I purchased mine from my local Home Depot and it was pretty expensive. Unfortunately, Home Depot does not carry these key blanks and their cartridge type of key cutting machine cannot duplicate two-sided keys like these. The local locksmiths I've used before typically charge a quite a bit for their services, so instead of using a locksmith to cut these key blanks, I took them the to my local Ace Hardware store. Although my local Ace Hardware doesn't carry these key blanks, they do have an old fashion key cutting machine that can duplicate two-sided keys and will duplicate them for a very reasonable price.

They are just the replacements the manufacturer recommended. Then I went to a professional locksmith to get them cut as instructed. No complaints 👌
