No lights and no engine sound. Mechanic's Assistant: Is the car in "Park" or "Neutral?" Do you know if your car has a "wheel lock" feature? Park .

Hi! My name is \*\*\*\*\* \*\*\*\*\* I will be able to assist you. I’m sorry that you’re having trouble with your vehicle. Don’t worry though, we’ll be able to figure this out. 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. Sometimes it may take a moment for me to respond because I may have to look up information about your concern. I appreciate your patience and will provide responses as soon as possible. If you need the key programmed then you'll have to call an automotive locksmith to come out and program it or you'll have to bring it to a repair shop. The vehicle will not start when the key is not programmed. This takes a special scan tool with programming capability. My goal is to earn a 5 star rating experience. Do you have any questions? Please feel free to reply back to me. If I’m not online at the time, I will respond ASAP when I get back.
