You will need a new replacement key and this has to be obtained from a dealer.The dealer orders it per your vehicles VIN number and a used key from ebay or any other place will not work on this model here.The key comes pre programmed ready for your vehicle from a dealer.I would start with this and if this does not correct the issue then you want to check and make sure the battery has a good charge and isnt faulty.In some cases the electronic ignition switch itself can be faulty and cause the key message and no start and may need replaced as well.This would have to be tested further though after the key is ordered in to see if it needs replaced.
When a dealer orders in the key it usually comes in over night.
