How to Fix Car Ignition Switch Problems

If your vehicle starts and runs but the ignition switch doesn't turn over the spark plugs, it could be a myriad of causes. Some are simple and inexpensive to fix, others require specialized tools and assistance from an expert mechanic.

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

Battery

It could be that your battery is dying if your car isn't starting. This is a frequent issue that can be fixed with an extra jump or charging the battery. If this doesn't fix the issue your ignition switch could be defective. This component is responsible for transferring battery power to other electrical components, such as the starter motor and the ignition coil. If the ignition switch is not working properly it will not allow current to flow through, and the engine will not begin.

The battery is the main source of the electrical energy in your vehicle. It's a black box with positive (+) and negative (-) terminals that are on top. The terminals may be corroded and stop the battery from providing electricity to the rest of the vehicle. By disconnecting the battery, you can make use of a wire bristle to remove any corrosion. You can also apply a baking soda solution to clean the terminals.

It is also possible that your car's battery is nearing the end of its life and requires replacement. A new battery will supply the proper voltage to your vehicle's spark plugs. This is essential for a functioning engine.


The ignition coil is responsible for turning low voltage from the battery into high voltage, which will then ignite the spark plugs in your car to start the engine. If the ignition coil is defective it will not be in a position to ignite the plugs and your engine will not start. You can test the ignition coil by checking for a spark inside 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 grinding sound as you turn the ignition key it is a sign that the starter bearings are deteriorating. It can be an expensive repair so it is best to replace your starter motor when you begin to begin to notice signs of wear. It's a relatively simple process that involves replacing some bolts and parts.

Alternator

The alternator is the one that charges your battery and also powers the electrical components of your car when the engine is running. Check the battery first if you suspect your alternator is malfunctioning. This will enable you to determine if your alternator draining the battery or if your battery is old and requires replacement.

The alternator in your car also provides the power to the windshield wipers, dash lights, electric steering, power windows, heated seats and your radio when the vehicle is idling. You can use a voltmeter check your battery and the alternator for the proper voltage levels. If your battery is less than 6 volts, it must be charged immediately or replaced. A dead or weak battery can also stop the starter motor from cranking the engine and will require additional jumper cables to start your car.

Before you begin dismantling the alternator, switch off the ignition and secure all doors. You should also disconnect the negative cable from the battery, and then put it away somewhere safe and put on safety gear. Consult a vehicle's specific repair manual for instructions on how to access the alternator as well as any other components you require to remove.

Once you've removed the belt, if your vehicle is equipped with one take off the warning light wire from the side of the alternator. It will typically connect directly to an alternator's terminal that's marked as WL or IND. Certain vehicles have a separate relay to perform this function. If your warning light doesn't come on, it is likely to be a different issue.

It is recommended to regularly check your alternator for indications of a malfunction. While you could perform some of the checks on your own, it's recommended to bring your vehicle to Les Schwab for a complimentary inspection and expert advice. Our trained technicians can test your battery, battery posts (the terminals marked + and +) for corrosion, fuses, relays as well as voltage output, cold cranking amps and more to determine what the problem is.

Starter Motor

The starter motor is a crucial element of the ignition system. It turns the engine to allow air to be drawn in which will ignite the fuel. When your car won't start it's usually due to a problem with the starter motor. There are a variety of troubleshooting techniques that can be used to help you diagnose and fix the issue.

When you turn on the ignition of your vehicle, a switch in the starter is activated by a pinion gear that fits into grooves on the flywheel. The pinion gear then turns the flywheel, which then begins the engine. The pinion gear retracts when you remove the key, thereby preventing damage.

The starter motor could be affected by a variety of things, including mechanical issues (such as teeth not lining up on the flywheel) or a dead cell. A faulty starter motor can sound like a dead cell phone battery. It will make a clunk sound as it tries but cannot turn the engine around.

If the starter motor isn't functioning, one of the first things a mechanic will look at is the state of charge on the battery and its terminals. If the battery has corrosion or is low it needs to be charged or replaced.

Depending on the extent of the problem, the mechanic may also test the solenoid on the starter using a multimeter. The solenoid is a huge magnetic switch that sends the power of the battery cables that are thick to the starter. The switch connects the long cable from the battery to the windings in the starter which turns the motor. It also triggers an axis rod to trigger an engaging fork which pushes the pinion to automatically engage with flywheel.

Another option is to bypass the ignition switch by using an extension wire. This is only an option for a short-term fix that you should not try it unless you're sure how to do it. ignition and key replacement 'll need to be careful about routing the jumper wire to battery terminals, and ensure that the switch is set to the "Start" position.

Ignition Switch

The ignition switch is where you insert your car key. This allows the system to allow electrical flow to the starter and then start the engine, but it isn't immune to wear and tear as other car parts. The switch can also get stuck inside its slot or become locked. You should be looking for issues regularly so you can act before the car stops working.

It could be locked if the key is difficult to turn or gets stuck in the ignition. This is a typical issue for a variety of vehicles and occurs due to a lack lubrication. You can apply a graphite- or silicone-based grease to lubricate the release pin. Spray some lubricant into the ignition and then turn the key. If you're stuck you can try using a piler or hacksaw blade.

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

A malfunctioning ignition switch could also cause lots of wear and tear on other components. If you have keys with many items, or a bulky one, this could put strain on the ignition switch and increase wear on the internal components. Extreme temperature fluctuations can affect the materials and lubricants in the ignition switch.

It is crucial to test the new ignition switch prior to reassembling other components and the steering column. Make sure the replacement ignition switch is working and that your engine is running smoothly. You should also double-check that the new ignition switch is compatible with your vehicle's model and model. It could be worth it to have a dealership install the ignition switch for you, if you aren't sure about your ability to do so. They can also test and connect any other components or replace them.
