Prefer I had a spare key made yesterday . I hope that not the problem
Expert:  peterpete190 replied 6 months ago.

O.k.,this indicates that a security component has failed on your model here.When this occurs suddenly like this here this usually indicates this is the cause and the faulty component needs located and replaced in order to have the key then relearned by a dealer with their Consult II.

Is this issue only occuring with the spare key and was it programmed to your model?

Customer: replied 6 months ago.
It happen with the key for the car not the spare key . I just tried the spare key and its not working also
Expert:  peterpete190 replied 6 months ago.

O.k.,this does indicate one of the security components at fault here needing replaced as something has failed and caused this fault here.

This can be the NATS immobilizer itself that is no longer recognizing the key and may need replaced.The only relearn for this is done with a dealers Consult II scan tool.You will need to have the fault codes read out/checked to see what codes are set with this issue here and then from there those codes diagnosed and repaired to locate and correct this fault.If only a relearn is needed this needs done with a dealers Consult II but I suspect a component has failed needing replaced unfortunately.
