How to Fix Car Ignition Switch Problems

If your car starts and runs, but the ignition switch won't switch over the spark plugs, there could be a number of causes. Some are easy and cheap to fix, while others require specialized tools and assistance from a mechanic.

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

Battery

If your car won't start it could be due to the battery being dead. This is a common problem that can be fixed with an extra jump or charging the battery. If this doesn't fix the issue, your ignition switch may be defective. The switch is the one that supplies battery power to other electrical components, including the starter motor and ignition coil. If the ignition switch is damaged it won't permit current to flow through, and the engine won't start.

The battery is the source of all the electrical energy in your vehicle. The battery is a black box with positive (+) and negatively (-) terminals on the top. The terminals can become corroded, preventing the battery from supplying electricity to the rest of the vehicle. By disconnecting the battery, you can make use of a wire bristle to get rid of any corrosion. You can also use baking soda to clean the terminals.

The battery in your car could be at the end of its life and need to be replaced. A new battery will provide the proper voltage to the spark plugs in your vehicle which is essential to ensure a functioning engine.

The ignition coil converts the battery's low voltage into high voltage that causes the spark plugs in your car and then start the engine. If the ignition coil is damaged, it won't be in a position to ignite the plugs and the engine won't start. The ignition coil can be checked by checking the engine for a spark or turning the key to check if it turns over.

It is also possible to replace the starter motor. If you hear a grinding noise when you turn on your ignition, it means that the bearings within the starter are starting to wear out. This can 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. Changing the starter motor is an easy process that requires replacing a few parts and bolts.

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. Examine the battery first if you suspect your alternator is failing. This will help you determine if your alternator is causing your battery to drain or your battery is old and requires to be replaced.

Your car's alternator also provides the power to the dashboard lights, windshield wipers and power windows, electric steering, heated seats and your radio even when the vehicle is idle. You can use a voltmeter to check your battery and the alternator for proper voltage levels. If your battery's voltage is lower than 6 volts, it should be replaced or charged right away. Batteries that are dead or not charged will also stop the starter from turning the engine on, and will require additional jumper cables in order to start your car.

Before you begin to dismantle the Alternator, shut off the ignition and lock all doors. You should also disconnect the negative cable from the battery, then tuck it away in a safe location and put on your safety equipment. Check out a specific vehicle repair manual to learn how to access the alternator, as well as any other components you require to remove.

If your vehicle has a warning light wire, you can remove it from the back of the generator following removing the belt. This wire will connect directly to an alternator terminal marked WL or IN. Some vehicles have a separate relay that can perform this function. If your warning light does not appear, it is likely to be an issue with your vehicle.

The alternator is an essential component of your vehicle, and you must inspect it regularly to look for signs of problems. You can do some of these checks by yourself, however it is best to bring your vehicle to Les Schwab so that they can look it over and provide you with expert advice. Our trained technicians can test your battery posts, battery (the terminals that are marked + and +) for corrosion and fuses, relays and voltage output as well as cold cranking amps and more to determine what the problem is.

Starter Motor

The starter motor is a crucial component of the ignition system. It turns the engine to allow air to be drawn in which will ignite the fuel. It is common for the starter motor to be the cause when your car isn't turning over. There are a number of troubleshooting methods to help you determine the problem and fix it.

When you turn on your vehicle's ignition 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 begins the engine. When you release the key, the pinion gear retracts, and disengages from the flywheel to prevent damage.

The starter motor could be affected by a variety of factors, including mechanical problems (such as teeth not meshing on the flywheel) or a dead cell. A faulty starter motor can sound like a dead phone battery. It can make a clicking sound as it attempts to turn the engine over.

The condition of the battery and the battery's terminals will be checked by a technician when the starter motor fails to work. If the battery is damaged or is not functioning properly it must be charged or replaced.

Depending on how severe the issue is, a mechanic could also test the solenoid with a multimeter. The solenoid, which is a large magnet switch, transmits an electric current from the thick batteries cables to the starter. This switch basically connects the battery cable to the wires inside the starter that actually activate the electric motor, plus it pushes an actuator rod that turns on an engaging fork, which will then push the pinion gear to automatically engage with the flywheel.

Another option is to bypass the ignition switch using a jumper wire. This is a temporary option, and it isn't recommended unless you're able to do it right. You'll need to be careful to connect your jumper wires to the battery terminals and make sure that the switch is in the "Start position".

ignition lock repair Switch

The ignition switch is the place where you insert your car keys. The system uses this to start the engine and to send electrical current to the starter. However, it is not immune to wear like other parts of the car. The switch may also get stuck inside its slot or become locked. You should be looking for issues regularly so you can act before the car won't start.

If your key is experiencing a struggle to turn or it gets stuck in the ignition, it could have been locked. This is a problem that is common in vehicles due to a lack oil lubrication. You can use a silicone or graphite-based grease to lubricate the release pin. Spray a bit of it into the ignition and try moving the key. If it's stuck you can try using a piler or hacksaw blade.

An ignition issue can cause a variety of other issues too. The anti-theft feature may stop working or the starter motor might not turn on when you insert the key. It can also cause auxiliary functions to lose power or not work at all.

A damaged ignition switch could also leave you with a lot of extra wear and tear on other parts. If you have a keychain with multiple items or a heavy one, this can cause strain on the ignition switch and accelerate wear on the internal components. Extreme temperature fluctuations can also affect the materials and lubricants in the ignition switch.

If you've purchased a replacement ignition switch, you need to test it before reassembling the steering column and other parts. Make sure the replacement ignition switch functions and that your engine is running smoothly. Also, make sure the new ignition switch is compatible with the vehicle's make and model. It might be worth it to get a dealership to install the ignition switch for you if are not confident about your ability to install it. They can also test and connect other components or replace them.
