Just to be clear, the engine will not crank or start and you don't have a key? How were you starting the vehicle when the key was not working?
If the key is the issue then we don't have any choice but to get the vehicle to dealer or have them come to you to program the key. Most dealers will not do this so unfortunately the only obvious recourse is to tow the vehicle to the dealer.
However, can you clarify for me how it was starting prior to this?
I am attaching the info below on how to program the keys but as you will see, it requires the scan tool if you don't have any keys left.
Please let us know if you have questions and the info requested. Thanks
