You can remove the trim on your steering column using special tools to gain access to the ignition cylinder module. Refer to your repair manual for 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 a bridge between two contacts, and controls the time when relays are activated and deactivated. Because it isn't able to transmit the full power of devices like the starter, it's a lighter-duty component that's less likely fail. The switch could still be damaged or corroded.

One sign of a damaged switch is difficulty turning the key. This can be caused by many factors, including the wrong way to insert a key, or deteriorating the mechanism over time. It is also common for people to misplace their car keys with another's, which could cause mechanical damage.

Before calling a locksmith you might want to try a few things. First, make sure that the battery is fully charged and there are no electrical issues with the system. It is also important to examine the voltage of each component to ensure they are sufficient power. After you've completed these steps, you're ready to begin troubleshooting.

Luckily, the ignition switch is pretty easy to replace. It's connected to the ignition cylinder, a round module that connects everything. You'll need to use a flathead and something long enough to press the pin in.

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.

To determine if the ignition switch is bad or the ignition coil is bad, you have to conduct an electrical test with a voltage meter. When the ignition switch has been set to run, the voltmeter should show around 12.6, If the voltage drops below that level, it's a sign there's an open circuit within the system. This could be a battery, solenoid, or the ignition coil.

Remove the electrical connector so that it does not interfere with the test. Then, set the voltmeter to the resistance or continuity mode and place one lead on one of the ignition switch terminals. The other lead should go to the positive terminal on the battery. If the voltmeter is "open" or does not register any voltage, you must replace the switch.

Use a brand new ignition key and a high-quality ignition cylinder when replacing the switch to ensure that your vehicle runs and starts properly. When you replace the switch, ensure not to hit the pins of the ignition cylinder using your tools. In the event of a collision, they'll become stuck and the engine won't run. You'll have to take off the steering wheel and gear selector in some vehicles to access the ignition cylinder. This isn't easy and isn't recommended until you have an owner's manual that says it's safe. Otherwise serious damage to the steering column or shifting mechanism is possible.

3. Check the Cylinder

If you've worked your way through the battery, wiring and ignition switch but can't get your car to start, it might be time to check the cylinder. It's the component that holds your key and is connected to the lock on the steering wheel so a would-be thief can't drive the car without keys.

To check the cylinder you will need to remove the cover for the steering wheel and disconnect the battery. Then, you'll be able pull out the old ignition switch and the cylinder made of metal. If you don't have an extra ignition switch lying around, it's possible to take your original ignition switch and cylinder to a locksmith to reuse them as long as they are in good condition. After replacing the ignition switch and cylinder ensure that you connect the wiring, secure it and reattach all covers and panels that you removed.

4. Check the Spark Plugs

The spark plug is the final link in your ignition chain. When it breaks, the engine can't run. This can take the form of your car ignition switch repair not starting at all, or it may start but run poorly. In either case, the cause is likely to be one of a few things that prevent or impair electricity from jumping across the spark plug gap, which allows your engine's gas and fuel mixture.

Before you begin working on your spark plugs, be sure you're working on a level surface and using gloves and tools that are protected to keep from being struck. Spark plugs can be extremely hot and could cause serious injuries if touched with bare hands.

When a spark plug goes bad, you might notice that the tip of the electrode's central portion has a slight brown or gray residue on it. The electrode could also have a dark layer. These deposits or fouling can hinder high-voltage electrical currents from jumping across the gap between the spark plug and starting an engine.
