I wonder why one key is orange and not green.
Don't lose the orange one. Keep it in a safe place.
It's a different color for a reason. The orange can be programmed to a new key, The green is the one you should use, cannot be programmed or copied.
If you lose the orange one, the bike will have to go back to Energica to get the mobilizer replaced. And you will then get a set of two new keys. You can still use the green but will never be able to copy it.
If you lose the green, no problem. Just have new keys made from the orange.
