How to Fix Car Ignition Switch Problems

If your car starts and runs, but the ignition switch isn't able to switch over the spark plugs, there may be a variety of causes. Some are easy and inexpensive to repair, while others require specialized equipment and help of a mechanic.

Lubricate the key socket first. You can use graphite powder or a silicon spray. Also, ensure that the ignition cylinder is free of obstructions and loose springs.

Battery

If your car doesn't start it could be because your battery is dead. This is a common issue which can be resolved by an extra jump or charging the battery. If this doesn't fix the problem, it is likely that your ignition switch is defective. This component is responsible for transferring power from the battery to other electrical components like the starter motor and the ignition coil. If the ignition switch is faulty it will not allow current to flow through, and the engine won't begin.

The battery is the primary source of electrical energy in your vehicle. The battery is a black box with positive (+) and negatively (-) terminals on the top. The terminals can become corroded and prevent the battery from supplying power to the rest of the vehicle. You can clean the battery terminals by disconnecting the battery and using a wire brush to get rid of any corrosion. You can also clean the terminals with baking soda.

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

The ignition coil converts the battery's low voltage into high voltage to spark the spark plugs inside your car, and to start the engine. If the ignition coil is faulty it will not be capable of sparking the plugs and the engine won't start. The ignition coil can be checked by examining the engine for a spark or turning the key to determine whether it spins.

You may have to replace the starter motor too. If you hear a grating sound when you turn your ignition key it is a sign that the starter bearings are deteriorating. It can be an expensive repair, so it is recommended to replace your starter motor as soon as you notice signs of wear. The starter motor can be changed by replacing a few bolts and parts.

Alternator

The alternator is the one that charges your battery and powers the electrical components of your car while the engine is running. If you suspect a issue with your alternator, you should test the battery first. This will allow you to determine if the alternator is draining the battery or if your battery is old and in need of replacement.

The alternator in your car also provides power for your dash lights, windshield wipers as well as power windows, electric steering, heated seats and your radio even when the vehicle is idling. A voltmeter can be used to test the voltage of your alternator and battery. If your battery is less than 6 volts, it should be replaced or charged right away. Batteries that are dead or not charged will also prevent the starter from turning the engine over and will require additional jumper cables in order to start your vehicle.

Before you begin removing the alternator, ensure that the ignition is turned off and all the doors are locked. It is also important to disconnect the negative cable from the battery, tuck it away in a safe place and put on your safety gear. Consult a repair manual specific to your vehicle to get instructions on how to remove the alternator or any other parts.

After you've removed your belt, if your vehicle has one remove the warning light wire from the back of the alternator. This wire will connect directly to the alternator terminal that is marked WL or IN. Some vehicles have an additional relay that performs this function. If your warning light does not appear, it is likely that there is a different issue.

You should regularly inspect your alternator for indications of malfunction. While you can do some of the tests on your own, it's recommended to bring your vehicle into Les Schwab for a complimentary inspection and expert advice. Our highly trained technicians can examine your battery posts, battery (the terminals marked + and -) for corrosion relays, fuses, voltage output as well as cold cranking amps and more to determine what the problem is.

Starter Motor

The starter motor is an important element of the ignition system. It is responsible for turning the engine to draw into air, which is necessary to ignite the fuel. It is typical for the starter motor to be the cause when your car won't turn over. There are a number of troubleshooting methods that can help you identify the issue and fix it.

When you turn on your car's ignition key, a switch within the starter activates a pinion gear that fits into grooves in the flywheel. The pinion gear turns the flywheel, which then starts 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 go wrong with the starter motor for example, an electrical issue in the internal windings, mechanical issues (such as teeth not connecting to the pinion gear or flywheel) or a dead battery. A damaged starter motor could sound like a dead phone battery. It can make a clicking sound when it tries but cannot turn the engine.

If the starter motor isn't working, one of the first things a mechanic should check is the state of charge on the battery and its terminals. If the battery is depleted or has rust on its terminals it will need to be charged or replaced.

Depending on how serious the issue is, a mechanic may test the solenoid by using a multimeter. The solenoid is a massive magnet switch, delivers an electric current from the thick batteries cables to the starter. This switch basically connects the thick battery cable to the wires inside the starter, which make the electric motor turn as well as it pulls an actuator rod that turns on an engaging fork, which in turn pushes the pinion gear to automatically engage with the flywheel.

A jumper wire can be used to disable the ignition. This is a temporary option, and it isn't recommended unless you are able to do it right. You'll need to carefully route the jumper wire to battery terminals, and ensure that the switch is in the "Start" position.

Ignition Switch

The ignition switch is the place where you insert your car key. The system uses this to start the engine and to send an electrical current to the starter. However it isn't immune to wear and tear like other parts of the car. The switch may also become stuck in its slot or locked. It is important to check for issues frequently to be able to act before the car won't start.

It could be locked if the key is difficult to turn or gets stuck in the ignition. This is a typical issue for many vehicles and happens due to a lack of lubrication. Using some graphite or silicone-based oil on the release pin can help. Spray some lubricant onto the ignition, and then move the key. If you're stuck then try using a hacksaw or piler blade.

A problem with the ignition can lead to a number of other issues too. The anti-theft system may stop working or the starter motor might not crank when you put in the key. This could also cause the other functions to stop functioning or cease to function.

A failing ignition key replacement cost switch can cause lots of wear and tear on other components. For instance, if you have a large keychain or a variety of items on your keychain, it can strain the ignition switch when you insert it in and can accelerate the wear on its internal components. Extreme temperature fluctuations may affect the materials and lubricants used in the ignition switch.

It is important to test the new ignition switch prior to reassembling other parts and the steering column. Make sure that the switch is working and that the engine starts without issues. Verify the compatibility of the new ignition switch with your car's model and make. It might be worth it to get a dealership to install the ignition switch for you if aren't sure about your ability to do so. They can also test the replacement and install any other parts that require to be connected or replaced.
