How to Fix Car Ignition Switch Problems

If your vehicle starts and runs but the ignition switch isn't able to turn over the spark plugs, there could be a number of reasons for this. Some are easy and cheap to fix, while others require specialized tools and help from an expert mechanic.

First, lubricate the key socket. You can apply graphite powder, or a silicon aerosol spray. Make sure that the ignition cylinder is clean and has no loose springs or obstructions.

Battery

It could be that your battery is dying if your vehicle won't start. This is a frequent issue which can be resolved by getting a jump or charging the battery. If this doesn't fix the issue the ignition switch could be bad. The switch is the one that supplies battery power to other electrical components, such as the starter motor and the ignition coil. If the ignition switch is not working properly it is not able to allow current be passed through, and the engine will not start.

The battery is the main source of the electrical energy in your car. It's a black box with positive (+) and negative (-) terminals on the top. The terminals may get corroded, preventing the battery from providing electricity to the rest of the vehicle. Clean the battery's terminals by disconnecting the battery and using a wire brush to remove any corrosion. You can also clean the terminals with a baking soda solution.

The battery in your car could be nearing the end of its life and will require replacement. A new battery will provide the correct voltage to your vehicle’s spark plugs. This is crucial to ensure that your engine is running properly.

The ignition coil is responsible for turning low voltage from the battery into high voltage that can ignite your car key ignition problems's spark plugs to start the engine. If your ignition coil is not working properly, it will not be able to spark the plugs. The engine will not start. You can test the ignition coil by looking for a spark in the engine or turning the key to see whether the engine is turning.

You might also have to replace your starter motor. If you hear a grating sound when you turn the ignition key it means that the starter bearings are worn out. It can be an expensive repair, so it is recommended to replace your starter motor immediately if you notice signs of wear. Changing the starter motor is an easy process that requires replacing some bolts and parts.

Alternator

The alternator is a device that charges your battery when your engine is running. It also powers your car's electrical components. If you suspect a issue with your alternator, you should test the battery first. This will enable you to determine if your alternator is draining the battery, or if your battery is old and in need of replacement.

While the vehicle is idle the alternator supplies power to the dash lights and radio. It also powers the windshield wipers as well as the power windows, the electric steering, heated seats, and the power windows. A voltmeter is a tool to test the voltage of your alternator and battery. If your battery has less than 6 volts it should be replaced or charged immediately. A dead or low-volt battery can also stop the starter from turning the engine on and may require additional jumper cables to start your car.

Before you begin removing the Alternator, turn off the ignition and secure all doors. Also, disconnect the negative cable from the battery, then tuck it away in a safe place and put on the safety equipment. Consult a vehicle's specific repair manual for guidance on how to access the alternator as well as any other components you'll need to remove.

If your vehicle is equipped with a warning light wire, you can remove it from the back of the generator following taking off the belt. This will usually connect directly to an alternator's terminal that is marked either WL or IND. Some vehicles have a separate relay to perform this function. If your warning light doesn't come on, it is likely that there is an issue with your vehicle.

It is recommended to regularly check your alternator for any indications of malfunction. While you can perform some of the checks yourself, it's best to bring your vehicle to Les Schwab for a no-cost inspection and expert advice. Our technicians can test for corrosion on your battery posts, battery (+ and -) and relays, fuses, and voltage output as well as cold starting amps and more.

Starter Motor

The starter motor is a crucial component in the ignition system. It is responsible for turning the engine so that it can take into air, which is essential to ignite the fuel. It is common for the starter motor to be the cause when your car doesn't turn. There are a variety of troubleshooting techniques that can be used to assist you in identifying and fixing the problem.

When you turn on your vehicle's ignition, a switch in the starter engages with a pinion gear that fits into grooves on the flywheel. The pinion gear turns the flywheel that begins the engine. When you release the key the pinion gear retracts and disconnects from the flywheel to prevent damage.

There are a myriad of things that can cause problems with the starter motor including an electrical failure in the internal windings, mechanical issues (such as teeth no longer connecting to the flywheel or pinion gear) or a dead battery. Often, a faulty starter motor can sound like a dead battery; it'll make a clicking noise when it attempts to turn over the engine, but it won't.

If the starter motor doesn't work One of the first things a mechanic would check is the state of charge on the battery and its terminals. If the battery is damaged or is depleted, it will need to charged or replaced.

Depending on how serious the issue is, the mechanic may also test the solenoid with a multimeter. The solenoid is a massive magnetic switch that delivers the power of the battery cables that are long and thick to the starter. The switch connects the long battery cable to the windings inside the starter that turn the electric motor and also pushes an actuator rod that turns on an engaging fork which in turn pushes the pinion gear to automatically engage with the flywheel.

Another option is to bypass the ignition switch using a jumper wire. This is a temporary fix, and you should not attempt it unless you are sure how to do it. You will need to carefully connect your jumper wires to the battery terminals and make sure that the switch is in the "Start position".

Ignition Switch

The ignition switch is the place where you insert your key into the car. This switch is used by the system to start the engine and to send electrical current to the starter. However, it is not immune to wear like other parts of the car. The switch may also become stuck in its slot or even locked. It is essential to check it regularly for problems so that you can act prior to the car not starting.

If your key is experiencing a struggle to turn or gets stuck in the ignition, it might be locked. This is a typical issue for many vehicles and happens because of a lack of lubrication. You can make use of a graphite or silicone-based oil to lubricate your release pin. Spray some lubricant onto the ignition and then turn the key. If it's stuck, make use of a piler or a hacksaw blade to assist in moving it.

An issue with the ignition can also lead to other problems. The anti-theft feature could not work or the starter motor could not turn on when you insert the key. This can cause secondary functions to stop working or stop functioning.

A malfunctioning ignition could cause extra wear and tear to other parts. For example, if you carry a bulky keychain, or several items on your keychain, it could strain the ignition switch when you plug it in, and could increase the wear and tear 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 the replacement ignition switch functions and that your engine is running smoothly. It is also important to confirm that the new ignition switch is compatible with your vehicle's model and model. It may be worthwhile to hire a dealership to install the ignition switch for you if aren't sure about your ability to do so. They can also test and connect other parts or even replace them.
