How to Fix Car Ignition Switch Problems

There are many reasons why your car may start and run but the ignition fails to turn on the spark plugs. 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. Also, make sure 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 which can be fixed with either charging your battery or the jump. If this does not fix the problem the ignition switch could be bad. The switch is the one that supplies battery power to the other electrical components, like the starter motor and ignition coil. If the ignition switch is defective it will not allow current to be passed through, and the engine won't start.

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

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

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 the ignition coil is damaged it will not be in a position to ignite the plugs and your engine will not start. The ignition coil can be checked by examining the engine for sparks or turning the key to see if it turns over.

It is possible to replace the starter motor, too. If you hear a grinding sound when you turn the key in your ignition, it means that the bearings inside the starter are beginning to wear out. This could be a costly repair, therefore it is recommended to replace the starter motor early on in the event that you notice signs of wear and wear. The starter motor can be replaced by replacing some bolts and other components.

Alternator

The alternator charges your battery and powers the electrical parts of your vehicle while the engine is running. If you suspect a issue with your alternator, you should test the battery first. This will help you determine if your alternator is causing the battery to drain or the battery is just old and should be replaced.

While the vehicle is in idle, the alternator provides power to the dash lights and radio. It also powers the windshield wipers as well as the power windows, the electric steering, the heated seats and the power windows. You can use a voltage meter to examine your battery and alternator for the proper voltage levels. If your battery's voltage is lower than 6 volts it should be charged immediately or replaced. A low or dead batteries can also stop the starter from turning over the engine and may require additional jumper cables to start your car.

Before you begin removing the alternator, ensure that the ignition is turned off and all doors are locked. Remove the negative cable and store it in a safe place. Wear safety equipment. Refer to a repair manual specific to your vehicle to get instructions on how to remove the alternator, or any other parts.

If your vehicle is equipped with a warning light wire, you can disconnect it from the back of the generator following removing the belt. This wire will usually connect directly to the alternator's terminal that is marked either WL or IND. Some vehicles, however, have a separate relay to perform this purpose. If your warning light doesn't come on, it is likely that you have an issue that is not related to the one you are experiencing.

You should regularly inspect your alternator for any indications of malfunction. You can perform certain of these tests yourself, but it is best to bring your vehicle to Les Schwab so that they can examine it and give you expert advice. Our certified technicians will examine your battery posts, battery (the terminals 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 turns the engine to allow air to be sucked in and ignite the fuel. It is common for the starter motor to be at fault when your car won't turn over. Fortunately, there are several methods of troubleshooting that can assist you in identifying and fixing the problem.

When you turn on your car's ignition key, a switch inside the starter turns on a pinion-gear that is fitted into grooves on the flywheel. The pinion gear turns the flywheel, which in turn starts the engine. When you release the key the pinion gear retracts and is released from the flywheel, thereby preventing damage.

There are a variety of things that can go wrong with the starter motor such as an electrical problem in the internal windings, a mechanical issue (such as teeth not meshing with the flywheel or pinion gear) or a dead battery. A malfunctioning starter motor may sound like a dead cell phone battery. It will make a clicking sound as it tries to turn the engine around.

If the starter motor isn't working One of the first things a mechanic would look at 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 problem is, the mechanic can also test the solenoid with a multimeter. The solenoid is a huge magnet switch, sends an energy surge from the long battery cables to the starter. The switch connects the long cable from the battery to windings in the starter which will turn the motor. It also pushes an axis rod to trigger an engaging fork that pushes the pinion to automatically engage with flywheel.

A jumper wire can be used to bypass the ignition. This is an interim solution that you should not try it unless you're certain of the procedure. You'll need to be careful 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 where you insert your car key. The system uses this to start the engine and send an electrical current to the starter. However it isn't 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 frequently for issues so you can act before the car stops working.

If your key seems to struggle to turn, or is stuck in the ignition, it might be locked. This is a typical issue for a variety of vehicles and occurs because of a lack of lubrication. You can use a silicone or graphite-based oil to lubricate your release pin. Spray some lubricant into the ignition, then move the key. If you're stuck then try using a piler or hacksaw blade.

A problem with the ignition could cause a host of other issues, too. The anti-theft system might not function or the starter motor might not turn on when you put in the key. This could also cause the secondary functions to stop working or cease to function.

A failing ignition can also cause extra wear and tear on other components. For instance, if you carry a bulky keychain or a variety of items on your keychain, it can strain the ignition switch when you insert it in, and could increase the wear on its internal components. Extreme temperature fluctuations can also impact the materials and lubricants in the ignition switch.

Once you have a replacement ignition switch, you need to test it prior reassembling the steering column and other components. Make sure the replacement ignition switch works and that your engine is running smoothly. Verify ignition key replacement of the new ignition switch with your car's model and make. If you're unsure of your ability to install the new ignition switch, it might be worth hiring a dealership service shop to do it for you. They can also test the new switch and install any other parts that need to be connected or replaced.
