How to Fix Car Ignition Problems

The car will not start unless the switch transmits an electrical signal to the starter. Normal wear and tear over time may cause the switch to malfunction.

Using special tools, you are able to remove 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 you check the Switch

One of the most frequently encountered ignition issues is a malfunctioning switch. It functions as an intermediary between two contacts, controlling the time when relays are activated and deactivated. Since it doesn't transmit the full power of devices such as the starter, it's a less powerful component that's less likely fail. The switch can still be damaged or damaged or corroded.

A malfunctioning switch is identified by a difficulty turning the key. This could be due to a number of factors, including the wrong way to insert a key, or deteriorating the mechanism over time. It's not unusual for people to confuse their keys with someone else's. This can cause mechanical damage.

Before calling a locksmith you can try a few things. First, you must ensure that the battery is fully charged and there aren't any electrical issues in the system. Also, you should verify the voltage of every component to ensure that they are providing enough power. Once you've completed these steps, you're ready to begin troubleshooting.

Fortunately the ignition switch is simple to replace. It is connected to the ignition module, a round component that connects everything. To replace it, you'll need an flathead screwdriver as well as something long enough to press the pin inside. This could be anything from paintbrush handles to Kabob skewer. However, it is best to avoid anything that is brittle and break within the hole.

When you're ready to do the job, you'll need to remove any trim pieces covering the area around the ignition switch. After removing the trim pieces, remove any screws holding the switch in place. Then carefully take it off. Depending on the model, you may be required to disconnect any wires that connect to it. If you have a manual for the vehicle you own, this will tell you exactly how to do it.

It is recommended to have the ignition switch replaced by a professional in the event that it isn't working. It's not easy to replace the ignition switch without removing the steering column. This could result in an accidental airbag deployment when you don't do it correctly. fix car ignition is best to let your local locksmith handle this.

2. Check the Wiring

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

The ignition switch is a low-voltage multi-pole electrical switch that is turned by the 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 active and it's impossible to start the engine.

You can use a voltmeter quickly test the ignition switch or ignition coil. When the ignition switch is set to run and the voltmeter is reading around 12.6, If the voltage drops below that level, it's a sign there's an open circuit in the system. This could be at the solenoid, the battery or even the ignition coil itself.

Connect the electrical connector to ensure that it doesn't interfere with the test. Then, set the voltmeter to the continuity or resistance mode and place one lead on one of the terminals on the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltmeter reads "open" or doesn't register any voltage then 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 runs and starts properly. Also, when you replace the ignition switch, be careful not to hit the pins of the ignition cylinder with your tools or they'll get stuck and the engine won't be able to start. In certain vehicles, you'll need remove the steering column and the gear selector in order to access the ignition cylinder. This can be difficult, and it is not recommended until you have an owner's manual that says it's safe. Otherwise serious damage to the steering column and shifting mechanism is possible.

3. Check the Cylinder

If you have tried the battery, the wiring and the ignition switch, but still cannot get your car to start, it may be time to check the cylinder. The cylinder is the piece which holds the key and is mechanically linked to the steering lock so that burglars won't be able to drive the car if it's not there.

You might notice that your key will not turn if the cylinder is worn out. The pins inside the cylinder can get stuck as they adapt to the shape of your key. This can cause your vehicle to not start. Alternatively, the cylinder may be loose, but a tap with the tack hammer may help to free it. Be sure not to mix up the springs and make sure your key is properly installed.

Another indication that your cylinder is going bad is when you need to turn the key and try different positions before it gets started. This is a red flag and should be corrected immediately, as it can only get worse over time.

To examine the cylinder, you will need to remove the cover on the steering wheel and disconnect the battery. The old ignition switch should be easy to remove, as well as the cylinder for ignition made of metal. If you don't own a spare switch, you may be able to bring your original ignition cylinder as well as switch to locksmiths for reuse as long they're in good shape. After replacing the switch and cylinder, be sure to reconnect the wiring harness and secure it and reattach any covers or panels you've removed.

4. Check the Spark Plugs

The spark plug is the last link in your ignition system chain. When it breaks, the engine can't run. This could take the form of your car not starting at all, or it may start but then run poorly. In any case, the root is likely to be one of several things that hinder or prevent electricity from crossing the spark plug gap, which allows your engine's gas and fuel mixture.

Before you begin working on your spark plugs, make sure you're working on a safe surface, using protective gloves and tools to avoid getting struck. Spark plugs can be very hot and can cause serious injuries if touched by hands without gloves.

You might notice a light gray or brown fleck on the tip of the electrode if the spark plug is damaged. It may also have a black coating on the opposite side of the electrode. These deposits or a build-up of fouling could stop high-voltage electrical current from jumping across the gap of the spark plug and starting an engine.





If you believe that your spark plugs may be at fault You can test them by removing them from their tube inside the ignition coil. This can be done by disconnecting the coil as well as the plug wire. Then, you'll be required to follow the correct procedure for your vehicle to take off the components that are covering the plugs. Once you have removed the plugs, you can place them on a surface that is grounded and turn the engine. If they're working, you should see an intense blue spark near the edge of the central electrode.

If you don't see a spark, you have found the problem. The next step is to work back through the ignition chain, testing each component until you find out what's stopping the spark plugs from doing their job. It's important to remember that all systems wear out and break down over time and this is particularly applicable to ignition systems. Routine maintenance can help to slow down the process and prevent a major headache in the worst case.
