How to Fix Car Ignition Problems


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

Utilizing specialized tools, you can remove your steering column trim and gain access to the ignition cylinder module. Refer to your repair manual for instructions on how to do this properly.

1. Make sure to check the Switch

One of the most common ignition problems is a bad switch. It regulates the time when relays are activated and deactivated through the use of bridge. It is less likely to fail due to the fact that it does not channel the full power of devices like the starter. However it's still possible for the switch to become damaged or corroded.

One indication of a defective switch is a difficulty turning the key. This can be caused by a variety of things such as incorrectly inserting the key or wearing out the mechanism over time. It's also commonplace for people to misplace their keys to their car with those of the keys of someone else, which can result in mechanical damage.

If the switch isn't working, there are some things you can try before calling a locksmith. First, ensure that the battery is charged and that there aren't any other electrical issues within the system. You should also examine the voltage of each component to ensure that they are supplying enough power. Once you've done these steps, it's time to start troubleshooting.

The ignition switch is easy to replace. It is connected to the ignition module, which is a round piece of equipment that holds everything together. It's necessary to use a flathead and a piece of material long enough to push the pin into. This could be anything from paintbrush handles to kabob skewer, but it is best to avoid anything that is brittle and break inside the hole.

When you're ready to do the work, you'll need to take away any trim pieces that cover the area around the ignition switch. After taking off the trim pieces, remove any screws that are holding the switch in position. Then carefully pull it out. Depending on the model, you may need to disconnect any cables connected to it. If you have an instruction manual for your vehicle and model, it will show you exactly how to do this.

It is best to have the ignition switch replaced by an expert when it's not working. It can be difficult to replace the ignition switch without disabling your steering column. This could lead to the unintentional airbag being deployed in the event that you don't do it correctly. It's best to let your local locksmith take care of this.

2. Verify the Wire

If you are unable to turn the key in the ignition or your car won't start, your problem could be related to any number of components of your vehicle's ignition system. Understanding how the ignition system works will help you determine the cause of the problem and make the necessary repairs.

The ignition switch is a low-voltage multi-pole electrical switch which is turned by the key. It has four positions that are off run, accessory, and "lock." If the switch is locked (which is typically shown by the red light), the ignition circuit is activated and it is inaccessible to start your car.

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 run position. If the voltage is below that it indicates that there is an open circuit within the system. It could be the solenoid, battery or the ignition coil.

Disconnect the electrical connector so that it does not interfere with the test. Set the voltmeter to the resistance or continuity modes and then place one lead on one of the terminals of the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltmeter shows "open" or does not register any voltage, it's time to replace the switch.

When changing the switch, make certain to use a new ignition cylinder and a good quality key cut to ensure that your car will start and run properly. When replacing the switch, ensure not to strike the pins of the cylinder's ignition with your tools. In the event of a collision, they'll 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 says it's safe. Otherwise, serious damage to the steering column and shifting mechanism is likely.

3. Check the Cylinder

If you have tried the battery, the wiring, and the ignition switch, but still can't get your car started, it may be time to examine the cylinder. It's the component that holds your key, and is mechanically connected to the steering wheel lock so that a potential thief cannot drive the car without a key.

If your cylinder is beginning to wear out, you could find that the key doesn't turn. Sometimes, the pins inside the cylinder get 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 a small tack hammer can aid in releasing it. Be careful not to mix up the springs and ensure that your key is properly installed.

Another indication that your cylinder is going bad is when you need to turn the key and test it in various positions before it starts. This is a sign of trouble and should be corrected immediately, as it will only get worse over time.

To examine auto locksmith ignition replacement , you will need to remove the cover on the steering wheel and disconnect the battery. The old ignition switch should be simple to remove, as well as the cylinder made of steel. If you don't have a spare ignition switch lying around, it's possible that you can take your original ignition switch and the cylinder to a locksmith in order to reuse them as long as they're in good condition. After replacing the ignition switch and cylinder ensure that you reconnect the wiring to secure it, then reattach the covers and panels you took off.

4. Make sure you check the Spark Plugs

The spark plug is your ignition system's last link. When it breaks it will stop the engine from running. This could take the form of your car 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 to run.

Before you begin working on your spark plugs, make sure you're working on a level surface and using protective gloves and tools to keep from getting zapped. Spark plugs can get very hot and can cause serious injuries if touched by hands without gloves.

You may notice a light gray or brown residue on the tip of the electrode if the spark plug is damaged. The electrode could also be covered with a dark coating. These deposits or a build-up of fouling could hinder high-voltage electrical currents from jumping across the gap between your spark plug and igniting an engine.

If you suspect that your spark plugs could be the culprit, you can test them if you remove them from the tube that is inside the ignition coil. You 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, and start the engine. If they're good you should see a bright blue spark crossing the gap at the tip of the central electrode.

If you do not see a spark you have identified the problem. The next step is to go back through the ignition system chain, testing each part until you can determine what is blocking the spark plugs from performing their job. It is important to keep in mind that all systems wear out and break down over time and this is particularly true of ignition systems. But, regular maintenance can help to slow down the process and prevent a major problem at the worst moment.
