How to Fix Car Ignition Switch Problems

If your vehicle starts and runs but the ignition switch doesn't switch over the spark plugs, there may be a myriad of causes. Some are easy and inexpensive to fix, whereas others require specialized equipment and the help of a mechanic.

Lubricate the socket of the key first. You can use either graphite powder or silicon aerosol spray. Make sure that the ignition cylinder is free of no obstructions or loose springs.

Battery

It could be that your battery is dead if your vehicle won't start. This is a common issue which can be fixed with charging the battery or making a jump. If this does not solve the problem, it is possible that the ignition switch is bad. This component supplies battery power to the other electrical components, like the starter motor and ignition coil. If the ignition switch is faulty 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 car. The battery is a black box with positive (+) and negatively (-) terminals on the top. The terminals could be corroded and stop the battery from supplying power to the rest of the vehicle. Clean the battery terminals by disconnecting the battery and using a wire brush to eliminate any corrosion. You can also apply baking soda as a 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 correct voltage to the spark plugs in your vehicle, which is required to ensure a functioning engine.

The ignition coil converts low voltage from your battery into high voltage that causes the spark plugs of your car, and to start the engine. If your ignition coil is not working properly, it will not be able spark the plugs. Your engine won't start. You can test the ignition coil by looking whether there is a spark in the engine or turning the key and seeing whether the engine is turning.

It is also possible to replace the starter motor. If you hear a grating sound when you turn on your ignition, it's a sign that the bearings within the starter are starting to wear out. It is a costly repair, so it is recommended to replace your starter motor immediately if you detect signs of wear. The starter motor can be replaced by replacing the bolts and parts.

Alternator

The alternator charges your battery and also powers the electrical components of your vehicle while the engine is running. If you suspect that there is a issue with your alternator, you must first test the battery. This will allow you to determine whether your alternator is causing the battery to deplete or if your battery is old and requires to be replaced.

Your car's alternator also provides power for the dash lights, windshield wipers, electric steering, power windows, heated seats and your radio when the vehicle is idle. A voltmeter can be utilized to check the voltage of your alternator and battery. If your battery has less than 6 volts, it must be replaced or charged right away. A dead or weak battery can also stop the starter motor from turning the engine over and will require additional jumper cables to get your car started.

Before you begin removing the alternator, ensure that the ignition is off and all doors are locked. Unplug the negative cable and store it safely. Wear safety gear. Consult a repair manual specific to your vehicle for instructions on how to remove the alternator or any other parts.

If your car has a warning light wire, you can disconnect it from the back of the generator after taking off the belt. The wire will be connected directly to an alternator terminal that is marked WL or IN. Certain vehicles have a separate relay that can perform this function. If your warning light does not blink, it's likely to be an issue that is not related to the one you are experiencing.

It is recommended to regularly check your alternator for any signs of malfunction. While you can perform some of the tests by yourself, you should bring your vehicle to Les Schwab for a complimentary inspection and expert advice. Our technicians can check for corrosion on your battery posts, battery (+ and -) and relays, fuses, as well as voltage output, cold starting amps, and much more.

Starter Motor

The starter motor is a crucial component of the mobile ignition lock repair services system. It is responsible for turning the engine to draw into air, which is necessary to ignite the fuel. It is quite common that the starter motor will be the cause when your car isn't turning over. Fortunately, there are several methods of troubleshooting that can help you diagnose and fix the problem.

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

The starter motor could be affected by a range of things, including mechanical issues (such as teeth not meshing on the flywheel) or dead cells. A damaged starter motor could sound like a dead cell phone battery. It will make a clicking sound as it tries to turn the engine.

If the starter motor doesn't work, one of the first things a mechanic should look at is the state of charge on the battery and its terminals. If the battery is damaged or is not functioning properly, it will need to recharged or replaced.

Depending on how severe the issue is, a mechanic may also test the solenoid using a multimeter. The solenoid is a large magnetic switch that delivers the power of the battery cables that are thick to the starter. This switch connects the bulky cable from the battery to windings in the starter which will turn the motor. It also triggers the rod to activate an engaging fork which pushes the pinion to automatically engage with flywheel.

A jumper wire can be used to bypass the ignition. This is a temporary solution but it shouldn't be recommended unless you are able to do it correctly. 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 Switch

The ignition switch is the place where you insert your key into the car. The system uses this to start the engine and send electrical current to the starter. However, it is not immune to wear and tear as other parts of the car. The switch may also get stuck in its slot or become locked. You should check for problems regularly to identify the problem before your car doesn't start.

It could have been locked if your key is difficult to turn or becomes stuck in the ignition. This is a common problem for many vehicles and happens due to a lack lubrication. You can use a silicone or graphite-based oil to lubricate your release pin. Spray a small amount into the ignition and try moving the key. If it's stuck then try using a hacksaw or piler blade.

An issue with the ignition may cause other issues. The anti-theft system may stop working or the starter motor might not crank when you put in the key. It can also cause auxiliary functions to lose power or cease to function altogether.

A malfunctioning ignition could cause additional wear and tear on other parts. If you own keys with many items or a heavy one, this could stress the ignition switch and increase wear on the internal components. Extreme temperature fluctuations can also affect the materials and lubricants in the ignition switch.

Once you have a replacement ignition switch, it's important to test it prior to assembling the steering column and other parts. Make sure that the switch is working and that the engine starts without any issues. You should also double-check that the new ignition switch is compatible with your vehicle's model and model. If you're unsure of your ability to install the new ignition switch it could be worth employing a dealership service shop to complete the task for you. They will also test the replacement and install any other components that need to be connected or replaced.
