How to Fix Car Ignition Switch Problems

If your car is running and starts, but the ignition switch won't turn on the spark plugs, there may be a myriad of reasons for this. Some are easy and cheap 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. Make sure that the ignition cylinder is free of no loose springs or obstructions.

Battery

If your car doesn't start, it could be because your battery is dead. This is a common problem that can be resolved by charging the battery or making an electrical jump. If this doesn't solve the problem, your ignition switch may be defective. The switch is the one that supplies battery power to the other electrical components, including the starter motor and ignition coil. If the ignition switch is not working properly it is not able to allow current be passed through, and the engine won't start.

The battery is the primary source of electrical energy in your vehicle. The battery is a black box with positive (+) and negative (-) terminals on the top. The terminals can become corrosion-prone, which can stop the battery from supplying power to the rest the vehicle. By disconnecting the battery, you can employ a wire bristle get rid of any corrosion. You can also apply a baking soda solution to clean the terminals.

Your car's battery could be nearing the end of its lifespan and will require replacement. A new battery will provide the correct voltage to your vehicle's spark plugs, which is required for a properly working engine.

The ignition coil is responsible for turning low voltage from the battery into high voltage that can ignite the spark plugs in your car ignition lock to start the engine. If your ignition coil is not working properly, it will not be able to spark the plugs. Your engine won't start. The ignition coil can be inspected by checking the engine for a spark or turning the key to see if it turns over.

It is also possible to replace the starter motor. If you hear a grinding noise when you turn the key in your ignition, it is a sign that the bearings within the starter are starting to wear out. It could be a costly repair, so it is recommended to replace your starter motor immediately if you begin to notice signs of wear. Changing the starter motor is an easy process that requires replacing some bolts and parts.

Alternator

The alternator is an instrument that charges your battery while your engine is running. It also provides power to your car's electrical parts. If you suspect a problem with your alternator, you must first test the battery. This will allow you to determine if your alternator draining the battery or if your battery is old and requires replacement.

While the vehicle is idle the alternator is able to supply power to the dash lights and radio. It also powers the windshield wipers, the power windows, electric steering, heated seats, and the power windows. A voltmeter is a tool to determine the voltage of your alternator and battery. If your battery is less than 6 volts, then it needs to be charged or replaced immediately. Batteries that are dead or not charged will also stop the starter from turning the engine over, and will require additional jumper cables in order to start your vehicle.

Before you begin to dismantle the alternator, switch off the ignition and secure all doors. Remove the negative cable and secure it. Wear safety equipment. Refer to a vehicle specific repair manual for instructions on how to access the alternator as well as any other components you require to take off.

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

It is recommended to regularly check your alternator for indications of malfunction. You can do some of these checks by yourself, however it is best to bring your vehicle into Les Schwab so that they can look it over and offer you advice from a professional. Our technicians can check for corrosion on your battery, battery posts (+ and -) fuse, relays, and fuses as well as voltage output and cold starting amps and much more.

Starter Motor

The starter motor is a crucial component of the ignition system. It rotates the engine to allow air to be sucked in which will ignite the fuel. It is quite common that the starter motor will be at fault when your car doesn't turn. There are a number of troubleshooting techniques that can help you identify the issue and resolve it.

When you turn on your car Ignition repair's ignition and key replacement key, a switch within the starter turns on a pinion-gear that is fitted into grooves on the flywheel. The pinion gear turns the flywheel, which in turn begins the engine. When you release the key the pinion gear retracts, and is released from the flywheel to avoid damage.

The starter motor can be affected by a variety of things, such as mechanical problems (such as teeth that don't mesh on the flywheel) or dead cells. Often, a faulty starter motor will sound like a dead battery; it will make a clicking sound as it tries to turn over the engine but can't.

The charge level and the terminals of the battery will be checked by a technician in the event that the starter motor does not work. If the battery is low or has rust on its terminals, it'll require charging or replaced.

Depending on how severe the issue is, the mechanic may also test the solenoid using a multimeter. The solenoid is a huge magnetic switch that sends a rush of power from the thick battery cables to the starter. This switch connects the thick cable from the battery to the starter's windings which turn the motor. It also pushes a rod to actuate an engaging fork that pushes the pinion to automatically engage with the flywheel.

A jumper wire can be used to bypass the ignition. This is an option for a short-term fix and you shouldn't try it unless you're confident about how to do it. You'll need to route the jumper wire to the battery terminals and make sure the switch is set to the "Start" position.

Ignition Switch

The ignition switch is where you insert your key into the car. This allows the system to enable electrical flow to your starter and to start the engine, however it's not immune from wear and tear as other parts of your car.

It could have been locked if your key is difficult to turn or gets stuck in the ignition. This is a common problem 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 a small amount into the ignition cylinder replacement near me and then try moving the key. If it's stuck then try using a hacksaw or piler blade.

An issue with the ignition can also cause other issues. The anti-theft system may stop working or the starter motor might not start when you plug the key. It could also cause other functions to lose power or not work at all.

A failing ignition can also cause additional wear and tear on other parts. For instance, if you have a heavy keychain or a variety of items on your keychain it can strain the ignition switch when you put it in, and could increase the wear on its internal components.
