How to Fix Car Ignition Switch Problems

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

First, lubricate the socket that holds the key. You can apply graphite powder or silicon spray. Make sure that the ignition cylinder is free of no obstructions or loose springs.

Battery

If your car isn't starting it could be because the battery is dead. This is a common issue that can be fixed with a jump or charging of the battery. If this doesn't fix the problem, your ignition switch may be defective. 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 won't begin.

The battery is responsible for all the electrical energy that is used in your vehicle. It's a black box with positive (+) and negative (-) terminals on the top. The terminals may get corroded, preventing the battery from supplying power to the rest the vehicle. Clean the battery's terminals by disconnection of the battery and using a wire brush to eliminate any corrosion. You can also use a baking soda solution to help clean the terminals.

Your car battery may also be nearing the end of its lifespan and need to be replaced. A new battery will provide the correct voltage to the spark plugs in your vehicle, which is required to ensure that your engine is running properly.

The ignition coil converts the battery's low voltage into high voltage, which causes it to ignite the spark plugs of your car and then start the engine. If your ignition coil is not working properly, it will not be able to ignite the plugs. The engine will not start. You can test the ignition coil by checking whether there is a spark in the engine or turning the key to see whether the engine is turning.

It is possible to replace the starter motor, too. If you hear a grinding noise when you turn the key in your ignition, it is a sign that the bearings in the starter are starting to wear out. This could be a costly fix, so it's best to replace the starter motor as soon as possible if you notice any signs of wear and tear. The starter motor can be replaced by replacing some bolts and other parts.

Alternator

The alternator charges your battery and powers the electrical parts of your vehicle while the engine is running. Test the battery first if you suspect that your alternator is failing. This will allow you to determine if the alternator is draining the battery, or if your battery is old and requires replacement.

Your car's alternator also supplies the power to the dash lights, windshield wipers, power windows, electric steering heated seats, and your radio even when the vehicle is idling. You can use a voltmeter test your battery and alternator to determine the proper voltage levels. If your battery is below 6 volts, it should be charged or replaced immediately. Batteries that are dead or not charged will also prevent the starter from turning over the engine and may require additional jumper cables to start your car.

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

After you've removed the belt, if your car is equipped with one take off the warning light wire from the back of the alternator. This will usually connect directly to a terminal on the alternator that's marked as WL or IND. Certain vehicles have a separate relay that can perform this function. If your warning light doesn't blink, it's likely that there is an issue that is not related to the one you are experiencing.

You should check regularly your alternator for indications of a malfunction. While you can do some of the tests by yourself, you should bring your vehicle into Les Schwab for a no-cost inspection and expert advice. Our trained technicians can test your battery, battery posts (the terminals that are marked + and -) for corrosion relays, fuses and voltage output as well as cold cranking amps and more to determine what the issue is.

Starter Motor

The starter motor is an essential component of the ignition system. It rotates the engine to allow air to be drawn in which will ignite the fuel. If your car won't start, it's typically caused by a problem with the starter motor. There are many ways to troubleshoot that can assist you in identifying and fixing the issue.

When you turn the key on the ignition of your vehicle the switch inside the starter is activated by a pinion gear that fits into grooves on the flywheel. The pinion gear turns the flywheel, which starts the engine. When you release the key, the pinion gear retracts, and disconnects from the flywheel to avoid damage.

The starter motor can be affected by a range of things, including mechanical issues (such as teeth not meshing on the flywheel) or a dead cell. A defective starter motor will just sound like a dead battery; it'll make a clicking noise as it tries to turn the engine but can't.

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

Depending on how G28 Car Keys is, a mechanic may also test the solenoid using a multimeter. The solenoid, which is a large magnet switch, sends an electric current from the thick batteries cables to the starter. This switch connects the bulky cable from the battery to the windings in the starter which will turn the motor. It also pushes an axis rod to trigger an engaging fork which pushes the pinion to automatically engage with the flywheel.

A jumper wire can be used to disable the ignition. This is an option for a short-term fix and you shouldn't try it unless certain of the procedure. You'll need to take care to connect your jumper wires 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 car key. The system uses this to start the engine and send an electrical current to the starter. However, it is not immune to wear and tear like other parts of the car. The switch could also become stuck in its slot or get locked. It is important to check it frequently for problems so that you can act prior to the car not starting.

If your key seems to struggle to turn or it gets stuck in the ignition, it may be locked. This is a common problem for many vehicles and is due to a lack lubrication. You can make use of a graphite or silicone-based lubricant to lubricate the release pin. Spray a little into the ignition and try moving the key. If it's stuck, use a piler or hacksaw blade to help move it.

An issue with the ignition may cause other issues. The anti-theft function may not function or the starter motor could not be able to turn on when you insert the key. This can cause auxiliary functions to stop working or stop functioning.

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

It's important to test the replacement ignition switch before reassembling other components and the steering column. Make sure the replacement ignition switch works and that the engine starts smoothly. Make sure that the new ignition switch with the vehicle's model and make. If you're unsure of your ability to install the new ignition switch, it might be worth hiring a service shop at a dealership to complete the task for you. They can also test and connect any other parts or even replace them.
