How to Fix Car Ignition Problems
The car won't start until the ignition switch transmits an electrical signal to the starter motor. Normal wear and tear over time may result in the switch not functioning properly.
Using specialized tools, you can take off your steering column trim and gain access to the ignition cylinder module. Check out your repair manual to learn how to do it right.
1. Make sure you check the Switch
One of the most frequently encountered ignition issues is a defective switch. It functions as a bridge between two contacts, controlling the time when relays are activated and deactivated. It is less likely to fail due to the fact that it does not channel full power of devices such as the starter. It is still susceptible to being damaged or corroded.
One indication of a defective switch is difficulty turning the key ignition replacement. This can be caused by various reasons, including incorrectly inserting a key or wearing down the mechanism over time. It's also commonplace for people to mix up their keys to their car with those of another's, which could lead to mechanical damage.
Before contacting a locksmith, you may try a few options. First, make sure that the battery is fully charged and there aren't any electrical issues within the system. It is also important to check the voltage of every component to ensure that they are providing enough power. After you've completed these steps, you're ready to begin troubleshooting.
The ignition switch is easy to replace. It's connected to the ignition cylinder, which is a round module that holds everything together. You'll need an elongated flathead as well as something that is long enough to push the pin into. You can employ anything from a paintbrush, to a Kabob stick, but be careful of anything that is brittle, as it can cause damage to the hole.
Remove any trim pieces that overhang the switch when you are ready to get started. After you've removed the trim pieces remove any screws that are holding the switch in position. Then carefully take it off. Depending on the model, you may also need to disconnect any wires connected to it.

The ignition switch is an electric switch with multiple poles that is operated by a key. It has four positions: off, accessory, run and "lock." When the switch is in the lock position (which typically has an indicator in red) the ignition circuit is in operation and it is not possible to start the engine.
To determine if the ignition switch is bad or if the ignition coil itself is bad, you must conduct a quick electrical test with a voltmeter. When the ignition switch has been set to run at a certain voltage, the voltmeter should read about 12.6, If the voltage drops below that level, it's a sign there's an open circuit somewhere in the system. This could be at the solenoid, the battery or even the ignition coil itself.
Remove the electrical connector from the ignition switch so that no other components can interfere with your test. Then you should set the voltmeter in the continuity or resistance mode and put one lead on one of the ignition switch terminals. The other leads should go to the positive terminal of the battery. If the voltmeter reads "open" or does not register any voltage, it's time to replace the switch.
If you're replacing the switch, make sure to use a new ignition cylinder and a top quality key cut to ensure that your vehicle will start and run correctly. When replacing the ignition switch, be cautious not to touch the ignition cylinder pins with your tools, or they'll get stuck and your engine won't start. You'll have to take off the steering wheel as well as the gear selector in some vehicles to access the ignition cylinder. This can be a challenge, and it is not recommended until you have an owner's manual that says it's safe. If you don't then you could cause serious damage to your steering column and the shift mechanism.
3. Check the Cylinder
If you've tried the battery, the wiring and the ignition switch but still can't start your car, it may be time to inspect the cylinder. The cylinder is the component that holds the key and is mechanically linked to the steering lock so that burglars won't be able to drive the car without it.
You may notice that your key will not turn if the cylinder has worn out. The pins in the cylinder may become stuck as they adapt to the shape of your key. This could cause your car to not start. Or, the cylinder might be loose however a tap using a small tack hammer can aid in releasing it. Be careful not to disturb the springs in the cylinder and ensure that the key is correctly installed prior to tapping.
If you need to jiggle and move the key before it will start, this is another sign that your cylinder has been damaged. This is a sign of trouble, and it must be fixed immediately as it will only worsen over time.
To check the cylinder, you'll need to unplug your battery and take off the cover around your steering wheel until you're able to access the ignition module. You'll then be able to remove the old ignition switch and the cylinder made of metal. If you don't have an extra ignition switch lying around, it's possible that you can take your original ignition switch and the cylinder to a auto locksmith ignition replacement in order to reuse them as long as they're in good condition. After replacing the switch and cylinder be sure to reconnect the wiring harness, secure it in place and reattach any covers or panels that you have removed.

You may notice a light brown or gray residue on the tip of the electrode if a spark plug is bad. It may also have a black coating on the opposite side of the electrode. These deposits or fouling can stop high-voltage electrical current from jumping across the gap of your spark plug, igniting an engine.
If you suspect your spark plugs could be the culprit you can test them if you remove the plugs from their tube inside the ignition coil. You can do this by disconnecting the coil from the plug wire, and following the correct procedure for your Car Ignition System Repair to remove components that cover the spark plugs. Once you have removed the plugs you can place them on a metal surface that is grounded and crank the engine. If they are working you will see an intense blue spark near the tip of central electrode.
If you do not detect a spark, you've discovered the problem. Next, you'll need to go backwards through the chain of ignition and check each component until the spark plugs aren't functioning. It's important to remember that all systems wear down and break over time and this is particularly true of ignition systems. Routine maintenance can help to reduce the time it takes to repair and prevent an issue at the worst possible time.
