How to Fix Car Ignition Problems

The car won't begin to start until the ignition switch sends the electrical signal to the starter motor. Over time wear and tear could cause the switch to malfunction.

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

1. Make sure to check the Switch

One of the most common ignition issues is a malfunctioning switch. It controls the time when relays are activated and deactivated by acting as bridge. It is less likely to fail because it does not channel the full power of devices like the starter. The switch can still be damaged or corrosion-prone.

One sign of a bad switch is a difficulty turning the key. This can be caused by a number of factors that include not inserting the correct key correctly or deteriorating the mechanism over time. It's also commonplace for people to mistake their keys to their car with those of another's, which could result in mechanical damage.

Before calling a locksmith you might want to try a few things. First, make sure that the battery is fully charged and that there are no electrical issues with the system. You should also examine the voltage of each component to make sure they're supplying enough power. Once you've completed these steps, you'll be able to begin troubleshooting.

The ignition switch is easy to replace. It's connected to the ignition and key replacement cylinder, a round module that connects everything. You'll need to use an elongated flathead as well as something long enough for you to insert the pin. You can make use of anything from a paintbrush to a Kabob stick, but be careful of anything that is brittle, as it can cause damage to the hole.

If you're ready for the job, you'll need to take off any trim pieces covering the area around the ignition switch. After that remove and loosen the screws that hold the switch in place and then carefully pull it out. Depending on the model, you may also have to unplug any wires that connect to it. Find out how to do this in the instruction manual for your vehicle.

If the ignition switch isn't functioning, it's best to have it replaced by professionals. Replacing it can involve disabling the steering column which could trigger an unintentional deployment of airbags if done incorrectly. This is why it's best to have your locksmith take care of this for you.

2. Check the Wire

Your car may not start if you cannot turn the key or if it isn't starting. This could be due to any number of components within the ignition system. It is important to know how the ignition system functions to be able to spot problems and make the right repairs.

The ignition switch is an electric switch with multiple poles that is operated by the key. It includes four positions "off", "accessory", "run" and the "lock". If the switch is in the lock position (which usually has a red indicator), the ignition circuit is active and it is not possible to start the engine.

You can use a voltage meter 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 drops below that, it indicates there's an open circuit somewhere in the system. It could be the solenoid, battery or the ignition coil.

Disconnect the electrical connector from the ignition switch so that there are no other components that could interfere with your test. Set the voltmeter in the resistance or continuity modes and connect one lead onto one of the terminals on the ignition switch. The other leads should go to the positive terminal of the battery. If the voltage gauge reads "open" or doesn't show any voltage it's time to replace the switch.

Use a brand new ignition key and a top-quality ignition cylinder when replacing the switch to ensure your vehicle is running and starts correctly. 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. In certain vehicles, you'll need remove the steering column and the gear selector to access the ignition cylinder. This can be a challenge and is not recommended unless you have an owner's manual that states it's safe to do this. Otherwise serious damage to the steering column or shifting mechanism is possible.

3. Check the Cylinder

If you've sifted through the wiring, battery and ignition switch and still can't get your car to start, it may be time to look at the cylinder. It's the part that holds your key, and is mechanically connected to the steering wheel lock so that a potential thief cannot drive the car without the key.

If your cylinder is beginning to wear out, you might notice that the key won't turn. Sometimes, the pins inside the cylinder are stuck when they adjust to the shape of your key, which could cause your car to not start. The cylinder may also be loose. A tap using the small tackhammer may help. Be sure not to mix up the springs and ensure that your key is properly installed.

If you have to jiggle and move your key before it can begin, it is a indication that your cylinder is become damaged. This is a negative sign and must be fixed immediately as it will only get worse with time.

To check the cylinder, you'll need to unplug your battery and remove the cover on your steering wheel until you can access the ignition module. The old ignition switch should be easy to remove, as should the cylinder made of steel. If you don't have an extra ignition switch lying around, it's that you could take your original ignition switch and cylinder to a locksmith to reuse them as long as they are 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 you've removed.

4. Check the Spark Plugs

The spark plug is the final link in your ignition system chain. The engine will not run when the spark plug is broken. It can be that your vehicle won't start at all or it will run badly. In either case, the cause is likely to be one of the things that prevent or impair electricity from crossing the spark plug gap, which allows your engine's gas and fuel mixture.

Be sure to wear protective tools and gloves before working with your spark plugs. Spark plugs can get very hot and could cause serious injuries if handled with hands that are not protected.

You might notice a light gray or brown residue on the edge of the electrode when the spark plug is defective. The electrode may also have a dark coating. These deposits or a build-up of fouling could hinder high-voltage electrical currents from jumping across the gap of your spark plug and igniting an engine.

If you suspect that 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 accomplished by disconnection of the coil and the plug wire. Then, you will need to follow the correct procedure for your car to remove the components that surround the plugs. After you have removed the plugs, you can place them on a grounded metal surface and turn the engine. If they're good you will see a strong blue spark extending across the gap in the middle of the central electrode.

If you do not detect a spark, you've discovered the problem. The next step is to work through the ignition chain, testing each element until you can determine what is stopping the spark plugs from performing their job. It's important to remember that all systems wear down and break down with time, and this is especially applicable to ignition systems. That said, routine maintenance can to slow down the process and avoid a big problem at the worst time.
