    • Hi Vish,
      If a security key is registered with a particular locksmith, you will have to order that key with them.No other locksmith will cut another locksmiths security key. If they no longer have the blanks, you will have to take that up with them and ask then to reorder them. If they were the people that sold you the key in the first place they should be able to reorder more keys to cut for you.
