Make sure all the fuses are good. It may have blown one of the fuses. IF that's good then make sure the anti theft is not triggered. First make sure your key fob has a good battery in it. Use the key fob remote to lock and unlock the doors. Turn the ignition on for 30 seconds and it should start. If it doesn't then lock and unlock the driver door with the physical key and turn the ignition on for 30 seconds. If it still doesn't start then there is a problem with the anti theft system and will require a scan tool to find the problem. To determine what the problem is you will need to use a scan tool to read the trouble codes (if any are stored) and also to view the data in the antitheft module to see what inputs / outputs are being recognized by the module. This will determine whether you have a problem with the key, receiver, module, or any other part of the system. Since there are not any common problems for this issue, I can not recommend any specific repair for this fault. If the module has any trouble codes stored let me know what they are and I will be able to pinpoint a specific problem for this issue. Hi!

Please understand that I do not know your knowledge or capabilities so I may need to ask questions to find out basic information to help solve your specific problem. With most newer automobiles, they have sophisticated electrical systems that can rely on different computers or modules to keep everything operating correctly. Most of the time specialized equipment is needed to test these systems. If you do not have this type of equipment for testing then we can only guess what the problem is. Yes there are common failures for certain symptoms but without testing, there’s no way to determine the specific problem unless testing is done. Who do I have the pleasure of speaking with today?
