How to Fix Car Ignition Switch Problems

There are a myriad of reasons your car may be running and starting but the ignition won't turn on the spark plugs. Some are simple and inexpensive to fix, others require special tools and assistance from a mechanic.

The first step is to lubricate the key socket. You can use graphite powder or silicon aerosol spray. Also, make sure the ignition cylinder is free of obstructions and springs that are loose.

Battery

If your car doesn't start it could be because your battery is dead. This is a frequent issue that can be resolved by a battery charge or the jump. If this doesn't fix the problem, your ignition switch may be defective. This component supplies battery power to other electrical components, like the starter motor and ignition coil. If the ignition switch is faulty, it won't allow current to flow through it and the engine will not start.

The battery is the primary source of electrical energy in your vehicle. The battery is a black, slender box with positive (+) and negative (-) terminals at the top. The terminals may become damaged, preventing the battery from supplying power to the rest of the vehicle. Clean the battery's terminals by disconnecting the battery and using a wire brush to eliminate any corrosion. You can also clean the terminals using baking soda.

Your car's battery could be at the end of its life and will require replacement. A new battery will supply the right voltage to the spark plugs in your vehicle which is necessary to ensure a functioning engine.

The ignition lock repair near me coil is responsible for converting low voltage from the battery to high voltage, which will then ignite the spark plugs in your car to start the engine. If the ignition coil is defective it will not be in a position to ignite the plugs, and your engine won't start. The ignition coil can be checked by examining the engine for a spark or turning the key to see whether it is turning.

It is possible to replace the starter motor, too. If you hear a grinding sound when you turn on your ignition it is a sign that the starter bearings are worn out. It can be an expensive repair, so it's best to replace your starter motor as soon as you begin to notice signs of wear. The replacement of the starter motor is an easy task that involves replacing some bolts and parts.

Alternator

The alternator is an instrument that recharges your battery while your engine is running. It also is the power source for your car's electrical components. Check the battery first if you suspect your alternator is failing. This will help you determine if your alternator is causing the battery to drain or your battery is old and should be replaced.

When the vehicle is idle, the alternator provides power to the dash light and radio. It also powers the windshield wipers as well as the power windows, the electric steering, the heated seats and the power windows. A voltmeter can be used to test the voltage of your alternator and battery. If your battery is less than 6 volts, it should be replaced or charged immediately. A low or dead batteries will also stop the starter from turning the engine on and will require additional jumper cables in order to start your vehicle.

Before you begin removing the Alternator, shut off the lost ignition key and lock all doors. Remove 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 component.

Once you've removed the belt, if the vehicle has one take off the warning light wire from the side of the alternator. This wire will connect directly to an alternator connector identified WL or IN. Certain vehicles, however, have a separate relay for this purpose. If your warning light doesn't appear, it is likely to be an issue with your vehicle.

You should regularly inspect your alternator for signs of malfunction. While you can do some of the checks yourself, it's best to bring your vehicle to Les Schwab for a no-cost inspection and expert advice. Our highly trained technicians can examine 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 an important element of the ignition system. It is responsible for turning over the engine to suck in air, which is necessary to ignite the fuel. If your car won't start, it's typically caused by a problem with the starter motor. There are a variety of troubleshooting techniques that can help you diagnose and fix the issue.

When you turn on your vehicle's ignition key, a switch inside the starter turns on a pinion-gear that fits into grooves in the flywheel. The pinion gear turns the flywheel, which in turn starts the engine. When you release the key the pinion gear retracts and disengages from the flywheel to prevent damage.

There are a myriad of things that can cause problems with the starter motor, including an electrical failure in the internal windings, mechanical issues (such as teeth not meshing with the pinion gear or flywheel) or a dead battery. A faulty starter motor can sound like a dead cell phone battery. It will make a clicking sound when it tries to turn the engine around.

If the starter motor isn't working One of the first things a mechanic would check is the state of charge of the battery and its terminals. If the battery is low or has rust on its terminals it will need to be charged or replaced.

Depending on the severity of the issue, the mechanic could examine the solenoid of the starter with a multimeter. The solenoid is a huge magnet switch, delivers a surge of power from the long battery cables to the starter. The switch connects the long battery cable to windings within the starter that actually make the electric motor turn as well as it pulls a rod that actuates an engaging fork, which in turn pushes the pinion gear to automatically engage with the flywheel.

Another option is to bypass the ignition switch with an extension wire. This is a temporary option but it shouldn't be recommended unless you are able to do it right. You'll need to be careful about routing the jumper wire through the battery terminals and make sure the switch is in the "Start" position.

Ignition Switch

The ignition switch is the place where you insert your car key. This allows the system to allow electrical flow to your starter and to start the engine, but it's not immune to wear and tear like other car ignition replacement parts. The switch can also get stuck in its slot or be locked. You should be looking for issues frequently to be able to 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 occurs in many vehicles due to a lack of grease. Using a silicone or graphite-based lubricant on the release pin could help. Spray some lubricant onto the ignition, then move the key. If you're stuck, try using a hacksaw or piler blade.

An ignition issue can lead to a number of other issues, too. The anti-theft feature could stop working or the starter motor could not be able to turn on when you insert the key. It could also cause other functions to cease functioning or cease to function at all.

A failing ignition switch can cause a lot of wear and tear on other components. If you own keys that have multiple items, or a bulky one, it can put strain on the ignition switch and accelerate wear on the internal components. Extreme temperature fluctuations may affect the materials and lubricants used in the ignition switch.

If you've got a new ignition switch, it's important to test it before reassembling the steering column and other components. Check that the replacement works and that the engine starts without any issues. You should also double-check that the new Ignition Lock Jammed switch is compatible with your vehicle's make and model. If you're not confident in your ability to install the new ignition switch, it might be worth employing a dealership service shop to complete the task for you. They can also test and connect other components or even replace them.
