Experienced mechanics share their insights in answering this question :
It is very possible the ignition switch is at fault. This is a known issue with the 2005-2007 Chevy Cobalt. These models are part of the General Motors Ignition Switch Recall. Contact your local Chevy dealer service department and provide them with the Vehicle Identification Number (VIN number) or check your VIN number on safercar.gov. If the vehicle falls within the recall, your Chevy dealer will replace the ignition switch free of charge under the parameters of the recall.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

Chevy is recalling certain model year 2005-2007 Cobalts and 2007 Pontiac G5 vehicles. “In the affected vehicles, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine,” according to the NHSTA recall alert.
The most common reasons a Chevrolet Cobalt won`t start are a dead battery, an alternator problem, or failed starter.
Bad or dead battery

The most common reason cars don`t start is a dead or faulty battery. Even though most cars run on gasoline, they all require electrical power to function. The starter that cranks your engine to start requires an electrical signal to fire.

One of the most likely culprits for a stuck ignition key is the steering wheel locking mechanism. When a vehicle is parked, the steering wheel can lock. That`s great for theft prevention, but it also prevents the key from turning or being removed from the ignition switch.
Why won`t my car start but I have power? If you attempt to start up your car but the engine won`t turn over and the dashboard lights up, then you most likely have an issue with your battery. You could have a damaged or corroded battery terminal, which is stopping the engine from starting up when you fully turn the key.
The most common reason a Chevy car (or any car) won`t start is a dead battery. If you have a battery tester, check your charge to see if it`s low. A dead battery can also be jumpstarted with jumper cables.
LEAVING YOUR KEY CLOSE TO YOUR CAR

Leaving your car key in your car overnight or even on a hook near the car is not recommended. If the fob is too close to your car, it can continue to communicate with it, which could drain the battery.

If your battery dies in your key fob, you can still get in and start your car (if equipped).
Bad Sensors

One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.

If your car won`t start, but your battery is fine, chances are you have a bad alternator. This is another charging system issue, like a dead battery, that won`t let you start your car.
How can I tell if my ignition switch is failing? A bad ignition switch will have problems with starting the engine, keeping it running, or engaging other systems when the key is turned. You might also have issues turning the key.
Locate and open the fuse box.

In some vehicles, the fuse box is located in the glovebox. You may need to refer to your vehicle`s manual to find your fuse box. Pop the hood and remove the cover of the fuse box. Here, you`re going to check the fuse for your ignition switch relay.

If the engine cranks, but the car doesn`t start: Bad fuel pump: A faulty fuel pump won`t deliver fuel to the engine, even if you`ve just filled up. Bad spark plugs: Without hot sparks to ignite the fuel charge in each cylinder, there is no combustion and no expansion of the burning mixture.
If you turn the key and hear the starter spinning madly but don`t hear the engine cranking, then the pinion gear isn`t thrusting forward. If you turn the key and hear crunching and gnashing, then the teeth on the pinion gear, or the flywheel, or both, are probably damaged.
A dead battery in your key fob means it can`t broadcast the signal the ignition system is looking for. If your car or truck can`t detect the correct signal, then the ignition will remain locked, and you won`t be able to start your car with the fob in your pocket.
If I change the battery in either the car or key fob do I have to reprogram the key fobs? No, The key fobs use non-volatile memory, meaning that they will never lose their programming if power to either the key fob itself or the module is lost.
A typical problem with the ignition switch is when your car fails to start. This sign forces you to keep making attempts to turn the engine, draining and, therefore, killing your battery. At same time, idling your car can also cause a stalling.
The majority of cars now have remote central locking, however, with a flat or dead battery this won`t work and you will be forced to use the key to open the car doors.
Dismantle the plastic cover below the steering wheel which houses all the electronics. Then insert a screwdriver into the ignition flaps and force it in using a hammer or by using a drill first. Then turn the screwdriver in the same direction you would as the car key. This will start the car.
If your key fob still isn`t functioning after you`ve replaced the batteries, the problem may be with the internal contacts, such as the buttons or the battery connector terminals. It`s also possible that your car and remote unpaired from each other after you took the batteries out.
Poor Engine Performance

You bet. Moreover, you may also notice poor acceleration, engine misfires, and even stalling. Bad oxygen sensors disrupt all kinds of essential engine functions, including engine timing, combustion intervals, and air-fuel ratio.

A dead battery in your key fob means it can`t broadcast the signal the ignition system is looking for. If your car or truck can`t detect the correct signal, then the ignition will remain locked, and you won`t be able to start your car with the fob in your pocket.

Okay so when I turn my lights on at night my brake lights do not work, when I don’t have my lights on they work fine.
ANSWER : Hi there. Based on your inquiry, it’s highly probable that you have a damaged light switch or some electrical fault inside the turn signal relay. However, it’s also possible that the brake switch above the brake pedal could also be the source of your problem. Due to the fact that multiple electrical components might be causing this issue, it’s a smart idea to first have a professional mobile mechanic complete a brake lights are not working inspection, so they can determine what’s causing all of these issues and recommend the right repairs.

Car won’t start. The check engine light, battery light, and oil change light are coming on. I tried jumping the car and nothing happened. Why won’t my car start?
ANSWER : Hi and thanks for contacting Your Mechanic. If sometimes your vehicle will start with the new alternator and sometimes it won’t, then there is a loose connection in your charging system. Check all of the wires to the alternator and to the battery. Make sure that the battery cables are clean and tight. Make sure that the wires to the starter are clean and tight. A loose ground to the ignition system will cause the vehicle to not crank over. Check all of the ground wires from the battery to the starter. Make sure that they are clean and tight. If you need further assistance troubleshooting your no start situation, then seek out a technician, such as one from Your Mechanic, that can assist you.

Battery and oil light come on when trying to start car, take keys out try again car starts no problem and lights go away
ANSWER : Of course, don’t switch gears without being fully stopped, unless your Owner’s Manual or the manufacturer has alternative advice. However, the gear shift issue has no relation to the no-start problem you are describing. Inasmuch as you only have 6,000 miles on the car, the "constant on and off" that you believe has occurred is meaningless in comparison to the expected total vehicle service life. That is, assume what you perceive as "constant on and off", during merely 6,000 miles, might be equivalent to using the car "normally" for three years. A new car should be trouble free for at least 5 years, unless there is a defect, so your "constant on and off" is not a causal factor for any fault on the vehicle. What you might have is a defect in the ignition switch, or perhaps the immobilizer system, but if the problem is not in the switch itself, clearly there is an electrical problem.

If your vehicle is under warranty, by law the dealer MUST repair the issue you are describing within a prescribed time frame and number of "attempts", otherwise the dealer will run afoul of Federal and state Lemon Laws that give you very specific rights, and recourse (contact an Attorney; we are Mechanics, NOT attorneys). Consequently, if the vehicle is still under warranty, to save yourself money do be sure to seek a resolution from the dealer. If the vehicle is not under warranty, obviously a certified Mechanic from YourMechanic could identify the electrical fault and resolve this for you. If you want to go that route, please simply request a no start diagnostic -electrical system and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Car was working fine before but now bothing turns on at all, and no noise. Key remote also won’t un/lock car at all
ANSWER : Give the shifter a good wiggle forwards and backwards. If it starts after doing that, you may have issues with the shifter interlock or the shifter cable itself. If the shifter cable is loose or worn, it may not be allowing the shifter to be fully in park and causing issues with the ignition. If this does nothing to get the vehicle to start, then the ignition switch and/or ignition lock cylinder themselves may be at fault. The ignition lock cylinder car wear over time, as can the key(s). Try another key if you have one. If that doesn’t help, a new ignition with new keys may be the answer.

Car won’t turn over. No lights come on when I turn it. Can’t even lock my doorsvor push the seat up or back.
ANSWER : Your probably correct, it sounds as though your battery is done. But it also sounds like you have charging system issues. I’m not sure that fixing your battery and charging system will solve the problem with the car shutting off, but it’s possible that it will and it’s a darned good place to start. By contacting Your Mechanic, you can have a technician come to your home or office to check out your car and help you figure out what to do next.

Put key in ignition. Lights and everything come on for a second, then went off as I turned the key. Now no power, key stuck
ANSWER : Hi, thanks for writing in. This sounds like your battery cable connections are corroded or loose at the battery. Try to see if the battery connections are loose by wiggling them and see if power returns. If power returns, then have the cables removed, cleaned, and reconnected to test the battery. Hope this helps and best of luck!

My car shuts off when I turn on the light or even the turn signals please help need this car to get to work
ANSWER : Hi there. This type of electrical glitch can be very difficult to pinpoint or diagnose without a physical inspection. However, in general, the most common causes of this issue is an exposed electrical wire within the ignition system. It is best to have a professional mechanic complete an electrical problems inspection first in order to correctly diagnose and resolve this issue.
