You can remove the steering column trim using specially designed tools to access the ignition cylinder module. Consult your repair manual to learn how to do it correctly.
1. Make sure you check the Switch
One of the most frequently encountered ignition issues is a malfunctioning switch. It functions as bridge between two contacts, and controls the time when relays are activated and deactivated. It is more likely to fail since it does not channel full power of devices such as the starter. However, it's still possible for the switch to get damaged or corrosion-prone.
One sign of a damaged switch is the difficulty in turning the key. This can be caused by various reasons that include incorrectly inserting a key or wearing down the mechanism over time. It's not common to see people mix their keys up with those of others. This can result in mechanical damage.
Before calling a locksmith you may try a few options. First, you'll need to make sure that the battery is fully charged and that there are no other electrical issues that could be affecting the system. You should also test the voltage of each component to determine if it's supplying adequate power. Once you've done these steps, it's now time to begin troubleshooting.
Fortunately the ignition switch is easy to replace. It is connected to the ignition module, which is a round component that connects everything. To replace it, you'll require an flathead screwdriver as well as something that is long enough to push the pin into. This could be anything from an artist's brush to a Kabob skewer, but you should stay clear of anything brittle that could break inside the hole.
Remove any trimming pieces that are covering the area around the switch once you're ready to work.

The ignition switch is an electrical switch that has multiple poles and is operated by a key. It includes four positions "off", "accessory", "run" and the "lock". When the switch is in the lock position (which typically has the red indicator), the ignition circuit is active and it's not possible to start the engine.
You can use a voltmeter quickly test the ignition switch and ignition key replacement coil. When the ignition switch has been set to run at a certain voltage, the voltmeter should read approximately 12.6, If the voltage falls below that then there is an open circuit within the system. This could be at the battery, the solenoid or the ignition coil itself.
Connect the electrical connector to ensure that it doesn't interfere with the test. Set the voltmeter to the continuity or resistance modes and connect one lead on one of the terminals of the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltmeter reads "open" or doesn't register any voltage then it's time to replace the switch.
Use a new ignition key and a high-quality ignition cylinder when you replace the switch to ensure your vehicle starts and runs correctly. When replacing the ignition switch, be careful not to hit the ignition cylinder pins with your tools or they'll become stuck and your engine won't start.

This can be a challenge and isn't recommended until you have an owner's manual that says it's safe. If you don't then you could cause irreparable damage to your steering column and shift mechanism.
3. Check the Cylinder
If you've worked your way through the wiring, battery, and ignition switch but can't get your car to start, it could be time to examine the cylinder. The cylinder is the piece that holds the key and is mechanically attached to the steering lock so that thieves can't drive the car without it.
You might notice that your key will not turn if the cylinder has worn out. Sometimes, the pins inside the cylinder get stuck as they adapt to the shape of the key, which could cause your car not to start. Or, the cylinder might be loose however a tap using the tack hammer may aid in releasing it. Just be careful not to disturb the springs in the cylinder and ensure that the key is correctly inserted before tapping.
If you are required to move the key before it will begin, this is another indication that your cylinder is been damaged. This is a negative sign and should be corrected right away, since it will only worsen over time.
To examine the cylinder, you will need to remove the steering wheel cover and disconnect the battery. You'll then be able pull out the old ignition switch and the metal ignition cylinder. If you don't have an additional ignition switch around, it's likely possible to take your original ignition switch and the cylinder to a locksmith and reuse them, as long as they're in good condition.

4. Check the Spark Plugs
The spark plug is your ignition system's last link. The engine cannot run in the event that the spark plug fails. It could be in the form of your car not running at all, or it could start but not run well.

When a spark plug goes bad, you may notice that the tip of the central electrode has a slight brown or gray substance on it. The electrode may also have a dark layer. These deposits, also known as fouling, may prevent high-voltage electricity from jumping across the gap between the spark plug and sparking your engine.
If you suspect your spark plugs may be the cause You can test them if you remove them from their tube inside the ignition coil. This can be done by disconnecting the coil and the plug wire. Then, you will have to follow the proper procedure for your car to remove the components that surround the plugs. After you have removed the plugs, place them on a surface that is grounded and start the engine. If they are working you should be able to see a strong blue spark on the point of the central electrode.

The next step is to go back through the ignition chain, testing each component until you discover what's stopping the spark plugs from performing their job. All systems will get older and eventually break, and this is particularly relevant to ignition systems. However, regular maintenance can to slow down the process and avoid a big problem at the worst time.
