Can Fix Car Ignition Ever Be The King Of The World?
How to Fix Car Ignition Problems

The car won't start until the ignition switch sends the electrical signal to the starter motor. Normal wear and tear over time may cause the switch to malfunction.

You can remove the steering column trim using specially designed tools to gain access to the ignition cylinder module. Check out your repair manual to learn how to do it correctly.

1. Make sure you check the Switch

A malfunctioning switch is one of the most frequent ignition problems. It regulates the time when relays are activated and deactivated through the use of bridge. Since it doesn't harness the full power of devices like the starter, it's a less powerful component that's less likely fail. It is still susceptible to being damaged or damaged or corroded.

One sign of a bad switch is the difficulty in turning the key. This could be due to many things such as incorrectly inserting the key or deteriorating the mechanism over time. It's also common for people to mix up their car keys with another's, which could lead to mechanical damage.

If the switch isn't functioning there are a few things you could try before calling a locksmith. First, you'll need to make sure that the battery is fully charged and that there aren't any other electrical issues within the system. You should also examine the voltage of every component to determine if it's providing enough power. Once you've completed these steps, you'll be able to begin troubleshooting.

The ignition switch is simple to replace. It is connected to the ignition module, a round component that holds everything together. To replace it, you'll need a flathead screwdriver and something long enough to press the pin inside. You can make use of anything from a paintbrush to a kabob stick, but avoid anything brittle as it could break into the hole.

If you're ready for the work, you'll need to remove any trim pieces that cover the area around the ignition switch. After this take off and loosen any screws that keep the switch in place and then carefully pull it out. Depending on the model you might need to disconnect the cables that connect to it. You can find out how to do this in the manual of your vehicle.

If the ignition switch isn't working it's recommended to replace it by professionals. It's difficult to replace the ignition switch without removing your steering column. This could result in the unintentional airbag being deployed in the event that you don't do it correctly. It is recommended to leave it to your local locksmith to handle this.

2. Verify the Wire

The car may not start if you are unable to turn the key or if it won't start. This could be due a number components in the ignition system. Understanding how the ignition system works will help you identify problems and make the necessary repairs.

The ignition switch is a low-voltage multi-pole electrical switch which is operated by a key. It includes four positions "off", "accessory", "run" and the "lock". When the switch is locked (which is typically shown by the red light), the ignition circuit is in operation and it is not possible to start your vehicle.

You can use a voltmeter to quickly test the ignition switch or coil. The voltmeter should be reading around 12.6 volts when the ignition switch is in the running position. If the voltage is below that it indicates that there is an open circuit somewhere within the system. This could be the solenoid, the battery or the ignition coil.

Connect the electrical connector to the ignition switch to ensure no other components can interfere with your test. Then set the voltmeter to the continuity or resistance mode and put one lead on one of the ignition switch's terminals. The other lead should go to the positive terminal on the battery. If the voltmeter shows "open" or doesn't show any voltage then it's time to replace the switch.

Use a new ignition key and high-quality ignition cylinder when you replace the switch to ensure your vehicle runs and starts properly. When you replace the switch, ensure not to touch the pins of the ignition cylinder using your tools. Otherwise, they will get stuck and the engine will not run. In certain vehicles, you'll need to remove the steering column and gear selector to get access to the ignition cylinder. This can be difficult and isn't recommended until you have an owner's manual that states it's safe. Otherwise, serious damage to the steering column and shifting mechanism is possible.

3. Check the Cylinder


If you've worked your way through the wiring, battery, and ignition switch, but cannot get your car to start, it could be time to check the cylinder. The cylinder is the part which holds the key and is mechanically attached to the steering lock so that a would-be burglar can't drive the car without it.

If your cylinder has started to wear out, you could find that the key doesn't turn. Sometimes, the pins within the cylinder get stuck when they adjust to the shape of your key, which may cause your car not to start. The cylinder could also be loose, but a tap with the tack hammer may help to free it. Be careful not to mix the springs, and make sure your key is properly inserted.

Another sign that your cylinder is in trouble is when you have to turn the key and try multiple positions before it begins. This is a bad sign and should be corrected right away because it will get worse with time.

To examine the cylinder you'll have to disconnect your battery and remove the cover around your steering wheel until you are able to access the ignition module. The old ignition switch should be easy to remove, as should the cylinder for ignition made of metal. 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. After replacing the ignition switch and cylinder make sure to reconnect the wiring, secure it and reattach all covers and panels that you removed.

4. Make sure you check the Spark Plugs

The spark plug is your ignition system's final link. The engine won't start when the spark plug is broken. It can be that your car won't start at all or will run poorly. In either case, the reason is likely to be one of a few factors that block or hinder electricity from jumping across the spark plug gap which ignites your engine's air and fuel mixture to start.

Before you begin working on your spark plugs, make sure you're working on a safe surface and using protective gloves and tools to avoid getting zapped. Spark plugs are hot and can cause serious injury when you touch them with bare skin.

There may be a slight gray or brown residue on the tip of the electrode if a spark plug is bad. It could also have a black layer on the opposite side of the electrode. The deposits or fouling may prevent high-voltage electrical current from crossing the gap between your spark plug, igniting an engine.

If you believe that your spark plugs may be to blame You can test them by removing the plugs from their tube in the ignition coil. ignition key won't turn can do this by disconnecting the coil from the plug wire, and following the correct procedure for your vehicle to remove the components that cover the spark plugs. After removing the plugs, place them on a surface that is grounded. Then start the engine. If they are working you should see a bright blue spark near the point of the central electrode.

If you don't see a spark you have identified the problem. The next step is to work back through the ignition system chain, testing each part until you find out what's blocking the spark plugs from doing their job. It's important to remember that all systems wear down and break down over time, and this is especially the case with ignition systems. Routine maintenance can help to reduce the time it takes to repair and avoid a major headache at the worst possible time.
