Why is my car making a clicking sound when I try to start it? The lights are turning on for a little bit but the engine is not turning over.

It could be your battery, especially if you have left a light on overnight, or had the key in auxiliary mode for sometime as both of those will drain even a new batter in a short amount of time. If your battery is new you may be able to have it charged, but if your battery is older than 3 years you will probably need a new battery.
