How to Fix Car Ignition Switch Problems

There are a variety of reasons your car might run and start, but the ignition doesn't turn on the spark plugs. Some are easy and inexpensive to repair, while others require specialized equipment and the help of an expert mechanic.

Lubricate the socket of the key first. You can apply graphite powder, or a silicon aerosol spray. Make sure that the ignition cylinder has 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 that can be solved with a jump or charging of the battery. If this does not fix the problem your ignition switch could be defective. This component is responsible for transferring battery power to other electrical components like the starter motor and ignition coil. If the ignition switch is not working properly, it will not allow current to flow through, and the engine will not begin.

The battery is the source of all the electrical energy that is used in your vehicle. It's a dark box with positive (+) and negative (-) terminals on top. The terminals can get corroded, preventing the battery from providing power to the rest the vehicle. You can clean the battery's terminals by disconnection of the battery and using a wire brush to remove any corrosion. You can also apply baking soda to clean the terminals.

The battery in your car could be nearing the end of its life and will require replacement. A new battery will supply the proper voltage to your vehicle's spark plugs which is essential to ensure that your engine is running properly.

The ignition coil is responsible for turning low voltage from the battery into high voltage that will spark the spark plugs in your car to start the engine. If the ignition coil is defective and is not able to spark the plugs and your engine will not start. The ignition coil can be inspected by checking the engine for sparks or turning the key to determine whether it spins.

It is also possible to replace your starter motor. If you hear a grinding sound when you turn the key in your ignition, it's a sign that the bearings inside the starter are starting to wear out. It can be an expensive repair so it is best to replace your starter motor as soon as you detect signs of wear. The replacement of the starter motor is a relatively simple process that requires replacing the bolts and a few components.

Alternator

The alternator charges your battery and powers the electrical parts of your car while the engine is running. If you suspect a problem with your alternator you must first test the battery. This will help you determine if your alternator draining the battery or if your battery is old and requires replacement.

The alternator in your car also provides the power to the dashboard lights, windshield wipers and electric steering, power windows heated seats, and your radio even when the vehicle is idling. You can use a voltmeter examine your battery and alternator for proper voltage levels. If your battery is less than 6 volts it should be charged immediately or replaced. A low or dead batteries will also prevent the starter from turning the engine over, and will require additional jumper cables to begin your car.

Before you begin to dismantle the Alternator, shut off the mobile ignition lock repair services and lock all doors. Unplug the negative cable and secure it. Wear safety gear. Check out a repair manual that is specific to your vehicle for instructions on how to remove the alternator or any other parts.

After you've removed your belt, if the vehicle has one, disconnect the warning light wire from the back of the alternator. This wire will usually connect directly to the alternator's terminal that's labeled WL or IND. Certain vehicles have a separate relay that can perform this function. If your warning light does not come on, you should be able to identify a different issue.

You should regularly inspect your alternator for signs of malfunction. While you can do some of the checks by yourself, you should bring your vehicle into Les Schwab for a complimentary inspection and expert advice. Our highly trained technicians can examine your battery posts, battery (the terminals that are marked + and -) for corrosion, fuses, relays and voltage output and cold cranking amps, and more to determine what the issue is.

Starter Motor

The starter motor is an essential component in the ignition system. It rotates the engine to allow air to be sucked into it which will ignite the fuel. It is quite common that the starter motor will be at fault when your car won't turn over. There are a few troubleshooting methods to help you determine the issue and resolve it.

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

There are a myriad of things that can be wrong in the starter motor, such as an electrical problem in the internal windings, mechanical issues (such as teeth no longer connecting to the pinion gear or flywheel) or a dead battery. Often, a faulty starter motor will just sound like a dead battery. it'll make a click when it attempts to turn over the engine but can't.

The condition of the battery and the battery's terminals will be checked by a technician if the starter motor doesn't work. If the battery is low or has rust on its terminals, it'll need to be charged or replaced.

Depending on how severe the problem is, the mechanic may test the solenoid by using a multimeter. The solenoid is a large magnetic switch that transmits an electric current from the battery cables that are long and thick to the starter. The switch connects the long cable from the battery to the windings in the starter which turn the motor. It also pushes an axis rod to trigger an engaging fork which pushes the pinion to automatically engage with the flywheel.

Another option is to disable the ignition switch by using an extension wire. This is only a temporary fix and you shouldn't try it unless confident about how to do it. You will need to carefully connect your jumper wires to the battery terminals, and then make sure that the switch is in the "Start position".

Ignition Switch

The ignition switch is the place where you insert your car keys. It is used to start the engine and send electrical current to the starter. However it isn't immune to wear like other components of the car. The switch can also become stuck in its place or become locked. You should check for problems frequently to be able to act before the car ignition locked won't start.

It could be locked if your key is difficult to turn or becomes stuck in the ignition. This problem occurs in many vehicles because of a lack grease. Using a silicone or graphite-based grease on the pin that releases the key could aid. Spray a small amount into the ignition, and then try moving the key. If you're stuck then try using a piler or hacksaw blade.

An ignition issue can cause a variety of other issues as well. The anti-theft device may stop working or the starter motor may not start when you plug the key. It can also cause auxiliary functions to stop working or cease to function at all.

A malfunctioning ignition could cause extra wear and tear to other parts. If you have keys that have multiple items, or a large one, this can stress the ignition switch and accelerate wear on the internal components. Extreme temperature changes can also impact the materials and lubricants used in the ignition switch.

Once you have a replacement ignition switch, it's important to test it before reassembling the steering column and the other components. Make sure the replacement ignition switch functions and that the engine starts smoothly. It is also important to confirm that the new ignition switch is compatible with your vehicle's model and model. If you're not sure of your ability to install an ignition switch that is new it could be worth hiring a dealership service shop to do it for you. They will also test the replacement and install any other components that require to be connected or replaced.
