Wow, talk about frustration! Are you hearing a clicking noise as you try to turn the key? How many miles are on your vehicle?
What’s appears to be happening is the battery is sending an electric signal to the starter, but the starter is not able to receive it; therefore, the engine will not start. You will need to have an auto technician check out the starter to see if it has failed. How many miles are on your vehicle? I was asking about the mileage for your vehicle, as starters do not fail very often. They will generally last 3 or more years depending upon the driving habits of the vehicle’s owner.
Unfortunately, you will need to have the car towed to the repair shop. The technician will check the battery first to see if that could be the issue. It most likely is not the issue, but that is the starting point for diagnosing the problem.
