Notwithstanding getting new keys physically cut, can a key from another vehicle be "recoded" to a different vehicle????
You should be able to reprogram them using an IID or Nanocom. From memory, you use an existing key as the Master and then program the others to emulate it. Here's a snapshot of part of the IID manual which would indicate that you can do this.

4.7.8 Body Control/Processor
Key programming (VIN locked L319-04, L320-05)
Preparations
• Have all keys on hand including new keys
• Unlock the doors
• Close all doors including the tailgate
Instructions
A previously programmed key is required to start the process. II When calling the function, the IIDTool
will start displaying messages to guide you:
• “Each key is programmed at position 1 (accessory) <+>”
• “When completed turn last key at position 2 (ignition) <+>”
• “Reprogram all keys including new ones? <+> Yes, <-> No”, Press on the Speed + / Menu
Up button to continue.
• If the engine’s not running, the following message will be displayed: “Start Engine”
• Followed by “Turn Key to Pos. 1”, this will turn OFF the engine and the vehicle will remain in
accessory mode.
• The LED on the IIDTool will flash once to indicate key number one is being programmed. It will
turn solid to indicate completion.
• Remove the first key. The LED will flash to indicate it is waiting for the second key.
• Insert the second key and turn it to position 1.
• The LED on the tool will flash twice to indicate key number two is being programmed. It will turn
solid to indicate completion.
• Repeat until all keys are programmed.
• When the last key is programmed (LED ON), turn the key to position II.
• If successful, the message “Operation succeed <+>” will be displayed. Key programming is
now complete.
Note : II Once the key is in position I, the IIDTool LED is used instead of the dashboard to indicate
status or completion stage
App : Simply follow instructions on screen.
