You need to have a scan tool to read computer. when cranking vehicle do any icons light up? It seems that you have a immobilizer problem which is associated with the key possibly. Try another key. If that is not successful. You will have to have car professionally scanned to proceed with diagnosis try disconnecting the battery terminals positive and negative and touch them together for 30 seconds. Next reconnect cables to battery Then try to start car. The p0499 code should not keep car from starting, unless it is an indicator that the computer has issues . you need to have a high level scanner hooked up to car to read computer sub systems.
Testimonial: "the key has a chip in it and its the only one we have besides the one for the doors and trunk it will not start the car. it also showed a code po499"
