Hey, I'm Dusty, an auto expert at RepairPal's Car Genius team. I'm here to help! There are several factors that could be causing the intermittent no-start condition, such as electrical issues, a software or data security problem, or something else entirely. It also can increase the difficulty diagnosing the core issue causing the failure. I suggest starting by replacing the battery in the key fob with the type specified in the manual. If the key fob doesn't respond after replacement, please refer to the owner's manual to re-sync it with the vehicle. You can also find many helpful videos on YouTube that cover these processes. If these steps don't fix the issue, it's best to seek assistance from a professional for further diagnosis and repair, ensuring a quick and effective solution to the problem. If you have more questions or need help finding a RepairPal Certified shop in your area, please give us a call at 877-913-1554.
