Nine Things That Your Parent Taught You About Fix Car Ignition

How to Fix Car Ignition Problems

The car won't start unless the switch sends an electrical signal to the starter. Normal wear and tear over time can cause the switch malfunction.

Using specialized tools, you can remove your steering column trim and access the ignition cylinder module. Consult your repair manual for instructions on how to do this correctly.

1. Check the Switch

One of the most frequently encountered fix ignition switch issues is a defective switch. It acts as an intermediary between two contacts, and controls when relays activate and deactivate. It is less likely to fail because it doesn't channel full power of devices like the starter. The switch can still be damaged or corroded.

A defective switch can be identified by a difficulty turning the key. This could be due to various factors that include not inserting the key correctly or the mechanism wearing out over time. It's also commonplace for people to mistake their keys to their car with the keys of someone else, which can cause mechanical damage.

If the switch isn't working, there are some things you can try before calling a locksmith. You'll first want to ensure that the battery is fully charged and there are no electrical issues within 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'll be able to begin troubleshooting.

Fortunately, the ignition switch is pretty easy to replace. It is connected to the ignition module, a round piece of metal that connects everything. You'll need a flathead and something long enough for you to press the pin in. This could be anything from a paintbrush handle to a Kabob skewer. However, you should avoid using any brittle material that could break inside the hole.

If you're ready for the work, you'll have to take away 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 remove it. Depending on the model, you may have to cut off any cables connected to it. Find out how to do this in the instruction manual for your vehicle.

It is recommended to have the ignition switch replaced by an expert when it's not working. It's not easy to replace the ignition switch, without disabling your steering column. This could result in an unintentional airbag being deployed when you don't do it correctly. It's best to let your local locksmith handle this.

2. Verify the Wire

If you are unable to turn the key in the ignition and key replacement or your car won't start, the issue could be related to any number of parts of your car's ignition system. It's important to understand how the ignition system works so that you can pinpoint issues and make the necessary repairs.

The ignition switch is a low-voltage multi-pole electrical switch that can be turned by the key. It has four positions including off run, accessory, and "lock." If the switch is in the lock position (which usually has the red indicator) the ignition circuit is in operation and it's impossible to start the engine.

To determine whether the ignition switch is bad or if the ignition coil itself is faulty, you'll must conduct a quick electrical test with the help of a voltage meter. The voltmeter should read around 12.6 volts when the ignition switch is in the running position. If the voltage is below that it indicates that there is an open circuit somewhere within the system. This could be at the battery, the solenoid or even the ignition coil itself.

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

When you're changing the switch, make sure to use a new ignition cylinder and a top quality key cut to ensure that your vehicle will run and start correctly. When replacing the ignition switch, be careful not to hit the ignition cylinder pins with your tools or they'll get stuck and the engine won't start. In certain vehicles, you'll need to remove the steering column and gear selector to access the ignition cylinder. This can be difficult, and it is not 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've worked your way through the wiring, battery, and ignition switch and still you can't get your car start, it could be time to examine the cylinder. The cylinder is the part which holds the key and 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 may notice that the key won't turn. Sometimes, the pins inside the cylinder become stuck when they adjust to the shape of the key, which may cause your car key ignition replacement near me not to start. The cylinder could also be loose. A tap using the small tackhammer may help. Be careful not to jumble the springs within and make sure that the key is correctly installed prior to tapping.

Another indication that your cylinder is going bad is when you have to jiggle the key and try multiple positions before it gets started. This is a bad indication and should be corrected immediately, since it will continue to get worse as time passes.

To test the cylinder, you must remove the cover for the steering wheel and disconnect the battery. You should then be able to pull out the old ignition switch as well as the metal ignition cylinder. If you don't own a spare switch, you might be able to bring the original ignition cylinder and switch to locksmiths for reuse as long they're in good shape. After replacing the switch and cylinder, ensure that you reconnect the wiring harness and secure it and then reattach any covers or panels that you have removed.

4. Check the Spark Plugs

The spark plug is the ignition system's final link. When it breaks, the engine can't run. It can be that your vehicle won't start at all or it will run poorly. In either case, the cause is likely to be one of a few things that hinder or prevent electricity from crossing the spark plug gap which ignites your engine's air and fuel mixture to start.

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

If a spark plug goes bad, you might observe that the edge of the central electrode has a slight brown or gray substance on it. The electrode may also have an opaque coating. These deposits or a build-up of fouling could prevent high-voltage electrical current from crossing the gap between your spark plug and igniting an engine.

If you believe that your spark plugs are at fault you can test them by taking the plugs from their tube in the ignition coil. This can be accomplished by disconnection of the coil and the plug wire. Then, you will be required to follow the correct procedure for your car to remove the components that surround the plugs. After removing the plugs, place them on a metal surface that is grounded and start the engine. If they are working you should see a bright blue spark on the point of the central electrode.

If you do not see a spark you have found the issue. The next step is to go backwards through the van ignition repair chain and test each component until the spark plugs stop functioning. It is important to keep in mind 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 prevent major problems in the worst case.
