How to Fix Car Ignition Switch Problems

If your vehicle starts and runs but the ignition switch doesn't switch over the spark plugs, there could be a myriad of causes. Some are easy and cheap to fix, while others require special tools and assistance from an expert mechanic.

Lubricate the socket before you use it. You can use either graphite powder or silicon aerosol spray. Also, ensure that the ignition cylinder is free of obstructions and springs that are loose.

Battery

If your car won't start, it could be because your battery is dead. This is a common problem which can be fixed with a battery charge or the jump. If this does not fix the problem the ignition switch could be bad. This component is responsible for transferring power from the battery to other electrical components such as the starter motor and lost ignition key coil. If the ignition switch is defective, it will not allow current to be passed through, and the engine won't start.

The battery is the source of all electrical energy in your vehicle. It's a dark box with positive (+) and negative (-) terminals on top. The terminals may become corrosion-prone, which can stop the battery from providing electricity to the rest of the vehicle. Clean the battery terminals by disconnecting the battery and using a wire brush to eliminate any corrosion. You can also clean the terminals with baking soda as a solution.

It's also possible that your car's battery is at the end of its life and requires replacement. A new battery will provide the proper voltage to the spark plugs in your vehicle, which is required for a properly working engine.

The ignition coil converts low voltage from your battery into high voltage, which causes it to ignite the spark plugs inside your car and then start the engine. If the ignition coil is faulty and is not able to spark the plugs and your engine won't start. The ignition coil can be inspected by checking the engine for a spark or turning the key to check if it turns over.

You may also need to replace your starter motor. If you hear a grating sound when you turn your ignition key it means that the starter bearings are wearing out. It could be a costly repair, so it's best to replace your starter motor immediately if you notice signs of wear. Changing the starter motor is a relatively simple process that requires replacing the bolts and a few components.

Alternator

The alternator charges your battery and also powers the electrical components of your vehicle while the engine is running. If you suspect a problem with your alternator you should first test the battery. This will help you determine if your alternator draining the battery or if the battery is old and needs replacement.

The alternator in your car also provides power for the dashboard lights, windshield wipers as well as power windows, electric steering, heated seats and your radio when the vehicle is idling. A voltmeter can be utilized to check the voltage of your alternator and battery. If your battery is less than 6 volts, it should be replaced or charged right away. A dead or low-volt battery will also prevent the starter from turning the engine over and will require additional jumper cables to start your car.

Before you begin to dismantle the Alternator, shut off the ignition and lock all doors. Unplug the negative cable and store it in a safe place. Wear safety equipment. Refer to a repair manual specific to your vehicle to get instructions on how to remove the alternator or any other component.

If your car has a warning light wire, you can disconnect it from the side of the generator after taking off the belt. This will usually connect directly to an alternator's terminal that's labeled as WL or IND. Certain vehicles, however, have an additional relay for this function. If your warning light does not blink, it's likely that you have a different issue.

The alternator is a vital component in your vehicle, and it is important to check it frequently for signs of trouble. While you can do some of the tests yourself, it's best to bring your vehicle to Les Schwab for a no-cost inspection and expert advice. Our highly trained technicians can examine your battery, battery posts (the terminals that are marked + and +) for corrosion and fuses, relays as well as voltage output, cold cranking amps and more to determine what the problem is.

Starter Motor

The starter motor is an essential element of the ignition system. It is responsible for turning the engine so that it can suck in air, which is essential to ignite the fuel. If your car won't start, it's usually caused by a problem with the starter motor. There are several ways to troubleshoot that can help you diagnose the issue and resolve it.

When you turn on your vehicle's ignition cylinder replacement near me key, a switch inside the starter activates a pinion gear that fits into grooves of the flywheel. The pinion gear turns the flywheel which initiates the engine. When you release the key the pinion gear retracts, and disconnects from the flywheel to prevent damage.

The starter motor could be affected by a range of factors, including a mechanical problem (such as teeth not meshing on the flywheel) or a dead cell. A damaged starter motor could sound like a dead cell phone battery. It will make a clicking sound as it tries but cannot turn the engine.

The state of charge and the battery's terminals will be checked by a mechanic when the starter motor fails to work. If the battery is corroded or is low it needs to be recharged or replaced.

Depending on how serious the issue is, the mechanic can test the solenoid by using a multimeter. The solenoid is a huge magnetic switch that delivers the power of the thick battery cables to the starter. This switch essentially connects the thick battery cable to windings within the starter that turn the electric motor as well as it pulls the rod, which turns an engaging fork, which will then push the pinion gear to automatically engage with the flywheel.

Another option is to bypass the ignition switch by using a jumper wire. This is only a temporary fix and you shouldn't attempt it unless you are sure how to do it. You'll need to carefully route the jumper wire to the battery terminals, and ensure that the switch is in the "Start" position.

Ignition Switch

The ignition switch is the place where you insert your key into the car. It is used to start the engine and to send electric current to the starter. However, it is not immune to wear like other parts of the car. The switch can also become stuck in its place or become locked. It is important to check for issues regularly to identify the problem before the car stops working.

If your key seems to struggle to turn or it is stuck in the ignition, it might be locked. This is a typical issue for many vehicles and is due to a lack of lubrication. Using a graphite or silicone-based grease on the pin that releases the key could help. Spray some lubricant on the ignition, and then move the key. If it's still stuck employ a piler or hacksaw blade to assist in moving it.

A problem with the ignition can also cause other issues. The anti-theft function may not work or the starter motor could not be able to turn on when you insert the key. It can also cause auxiliary functions to cease functioning or cease to function at all.

A failing ignition can also cause extra wear and tear on other parts. For instance, if you have a large keychain, or several items on your keychain it could strain the ignition switch when you insert it in, and could increase the wear on its internal components. Extreme temperature fluctuations can affect the lubricants and materials used in the ignition switch.

If you've got a new ignition switch, it's crucial to test it before reassembling the steering column and other parts. Make sure that the new ignition switch functions and that the engine starts smoothly. Verify the compatibility of the new ignition switch with your car ignition lock's model and model. It may be worthwhile to have a dealership install the ignition switch for you, if you are not confident about your ability to install it. They can also test and connect other components or replace them.
