How to Fix Car Ignition Problems

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

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

1. Check the Switch

A bad switch is among the most frequently encountered ignition issues. It regulates the moment relays are activated, and deactivated, acting as a bridge. It is less likely to fail due to the fact that it doesn't channel full power of devices such as the starter. However it's still possible for the switch to become damaged or corroded.

One sign of a bad switch is difficulty turning the key. This could be due to many things, including not inserting the key correctly or wearing out the mechanism over time. It is also common for people to mix up their keys to their car with someone else's, which can cause mechanical damage.

If the switch isn't working there are some things you can try before calling a locksmith. First, you must ensure that the battery is fully charged and there aren't any electrical issues with the system. Also, you should examine the voltage of each component to ensure that they are sufficient power. After you've completed these steps, you'll be able to begin troubleshooting.

The ignition switch is simple to replace. It's connected to the ignition cylinder, a round module that connects everything. To replace it, you'll require an flathead screwdriver as well as something long enough to press the pin into. You can use anything from a paintbrush to a kabob stick, but avoid anything that is brittle, as it can be broken into the hole.

Remove any trim pieces that overhang the switch once you're ready to go. After removing the trim pieces, remove any screws holding the switch in position. Then carefully take it off. Depending on the model you may have to cut off any cables connected to it. If you have a manual for your vehicle and model, it will show you exactly how to do this.

If the ignition switch isn't working it is recommended to have it replaced by a professional. It's not easy to replace the ignition switch, without disabling the steering column. This could lead to an accidental airbag being deployed when you don't do it correctly. This is why it's best to have your local locksmith handle this for you.

2. Verify the Wire

If you're unable to turn the key in the ignition or your car isn't starting, your issue could be due to any number of parts of your car's ignition system. Understanding how the ignition system works will help you identify problems and make the appropriate repairs.

The ignition switch is a low voltage multi-pole electrical switch which is turned by the key. It has four positions, including "off", "accessory", "run" and the "lock". If the switch is locked (which is usually indicated by a red light) the ignition circuit is active and it is inaccessible to start your vehicle.

To determine if the ignition switch is damaged or if the ignition coil is defective, you will have to conduct an electrical test using a voltmeter. 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 within the system. This could be at the battery, the solenoid or at the ignition coil itself.

Connect the electrical connector to the ignition switch to ensure that no other components can interfere with the test. Set the voltmeter on the resistance or continuity modes and connect one lead onto one of the terminals of the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltmeter reads "open" or fails to register any voltage, you should replace the switch.

Use a brand new ignition key ignition replacement and high-quality ignition cylinder when replacing the switch to ensure your vehicle runs and starts properly. When replacing the switch, ensure not to touch the pins of the ignition cylinder with your tools. Otherwise, they will get stuck and your engine won't be able to run. In some vehicles, you'll have to remove the steering column and the gear selector to get access to the ignition cylinder. This isn't easy and isn't recommended until you have an owner's manual that states it's safe. Otherwise severe damage to the steering column or shifting mechanism is possible.

3. Check the Cylinder

If you have tried the battery, the wiring, and the ignition switch, but still can't start your car It could be time to examine the cylinder. The cylinder is the part that holds the key. It is mechanically attached to the steering lock so that burglars won't be able to drive the car if it's not there.

If your cylinder is beginning to wear out, you could be noticing that your key isn't able to turn. The pins inside the cylinder may become stuck when they adapt to your key's shape. This could cause your vehicle to not start. The cylinder might also be loose. Tapping it with a small tackhammer will help. Be sure not to mix up the springs and make sure your key is correctly installed.

If you need to jiggle and move your key before it will start, this is another sign that your cylinder has gone bad. This is a negative sign, and it must be fixed immediately as it will only worsen over time.

To test the cylinder, you'll have to disconnect your battery, and then remove the cover on your steering wheel until you can access the ignition module. The old ignition switch should be easy to remove, as well as the cylinder for ignition made of metal. If you don't have an extra switch, you might be able to bring your original ignition cylinder as well as switch to locksmiths for reuse as long as they're in good working order. After replacing the switch and cylinder, ensure that you reconnect the wiring harness, secure it in place and reattach any covers or panels that you have removed.

4. Check the Spark Plugs

The spark plug is the final link in your ignition chain. When it is damaged it will stop the engine from running. It could be that your vehicle won't start at all or will 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 ignites your engine's air and fuel mixture to run.

Before you begin working on your spark plugs, be sure that you are working on a safe surface, using gloves and tools that are protected to prevent being hit with. Spark plugs can be extremely hot and cause serious injuries if they are handled with hands that are not protected.

You might notice a light brown or gray residue on the top of the electrode if a spark plug is bad. It could also have a black layer on the sides of the electrode. These deposits, or corrosion, can prevent high-voltage electricity from jumping across the gap between the spark plug and sparking your engine.

If you think that your spark plugs are at fault You can test them by taking them from their tube inside the ignition coil. This can be done by disconnecting the coil from the plug wire and following the proper 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 begin the engine. If they're working, you should see a bright blue spark extending across the gap at the tip of the central electrode.

If you aren't seeing a spark, you have found the issue. The next step is to work back through the ignition 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 particularly applicable to ignition systems. Routine maintenance can help to reduce the wear and tear and avoid a major headache at the worst time.
