How to Fix Car Ignition Problems

The car won't begin unless the switch transmits an electrical signal to the starter. Normal wear and tear over time could result in the switch not functioning properly.

Utilizing specialized tools, you can take off the trim on your steering column and gain access to the ignition cylinder module. Refer to your repair ignition lock cylinder manual for learn how to do it right.

1. Check the Switch

A bad switch is among the most frequently encountered ignition issues. It functions as an intermediary between two contacts, controlling the relays' activation and deactivation. It is less likely to fail due to the fact that it does not channel full power from devices like the starter. However, it's still possible for the switch to become damaged or corroded.

One sign of a damaged switch is the difficulty in turning the key. This could be due to many things, including incorrectly inserting the key or wearing out the mechanism over time. It is also common for people to mistake their car keys with another's, which could cause 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 the battery is fully charged and that there aren't any other electrical issues that could be affecting the system. Also, you should test the voltage of each component to see if they're supplying adequate power. Once you've completed these steps, you're ready to begin troubleshooting.

Fortunately the ignition switch is pretty simple to replace. It is connected to the ignition module, a round component that holds everything together. You'll need an elongated flathead as well as something long enough for you to push the pin into. You can use anything from a paintbrush, to a kabob stick, but avoid anything that is hard as it could cause damage to the hole.

Remove any trim pieces that cover the area around the switch when you're ready to get started. Once you've done this, loosen and remove any screws that keep the switch in place, and then gently remove it. Depending on the model, you may also have to unplug the wires that connect to it. If you have a manual for the vehicle you own, this will tell you exactly how to do it.

If the ignition switch isn't functioning, it's best to have it replaced by an expert. Replacing it can involve disabling the steering column, which may trigger unintentional airbag deployment if it's done incorrectly. It's best to leave it to your local locksmith to handle this.

2. Verify the Wire

If you can't turn the key in the ignition or your car won't start, the issue could be due to any number of parts of your car's ignition system. It is important to know how the ignition system functions to be able to spot issues and make the necessary repairs.

The ignition switch is a low-voltage multi-pole electrical switch which is operated by a key. It has fill not turn if the cylinder is worn out. Sometimes, the pins inside the cylinder become stuck when they adjust to the shape of the key, which could 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 disturb the springs within and make sure that the key is correctly inserted before tapping.

If you need to jiggle and move your key before it can begin, this is another indication that your cylinder is been damaged. This is a red flag and needs to be fixed immediately, as it will only get worse with time.

To examine the cylinder you'll need to disconnect your battery and remove the cover from your steering wheel until you are able to access the ignition module. The old ignition switch should be simple to remove, as should the metal ignition lock repair cylinder. 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 locksmith and reuse them, as long as they are in good condition. After replacing the ignition switch and cylinder make sure to reconnect the wiring to secure it, then reattach the covers and panels you removed.

4. Check the Spark Plugs

The spark plug is the ignition system's final link. The engine cannot start if the spark plug breaks. It can be that your car won't start at all or it will run poorly. In either case, it is likely that one of several things are preventing or impeding electricity from jumping across spark plug gaps, which then ignites the fuel mixture and air within your engine.

Be sure to wear protective tools and gloves before working with your spark plugs. Spark plugs can be extremely hot and can cause serious injuries if touched by hands without gloves.

When a spark plug goes bad, you may observe that the edge of the central electrode is covered with some light brown or gray residue on it. The electrode could also be covered with an opaque coating. These deposits, also known as corrosion, can prevent high-voltage electricity from jumping across the spark plug gap and igniting your engine.

If you think that your spark plugs are at fault, you can test them by taking them from their tube in the ignition coil. This can be accomplished by disconnection of the coil and the plug wire. After that, you'll be required to follow the correct procedure for your vehicle to take off the components that are covering the plugs. After you have removed the plugs, place them on a surface that is grounded, and begin the engine. If they are good, you should see a bright blue spark across the gap between the tip of the central electrode.

If you do not see a spark, you've found the issue. The next step is to go through the ignition chain, testing each element until you can determine what is hindering the spark plugs from performing their job. All systems wear out and eventually break and this is especially relevant to ignition systems. However, regular maintenance can slow the process down and avoid a major problem at the worst moment.
