How to Fix Car Ignition Switch Problems If your vehicle starts and runs but the ignition switch won't turn on the spark plugs, there could be a myriad of reasons. Some are easy and cheap to fix, while others require specialized tools and assistance from an expert mechanic. First, you need to lubricate the socket that holds the key. You can use graphite powder or a silicon spray. Make sure that the ignition cylinder is free of no obstructions or loose springs. Battery If your car isn't starting, it could be because the battery is dead. This is a common issue that can be resolved by charging the battery or making a jump. If this doesn't solve the problem, it is likely that your ignition switch is not working properly. This component carries battery power to other electrical components, including the starter motor and the ignition coil. If the ignition switch is damaged it is not able to allow current flow through, and the engine won't start. The battery is responsible for all the electrical energy in your vehicle. It's a black box with positive (+) and negative (–) terminals on top. The terminals may become corrosion-prone, which can stop the battery from providing power to the rest the vehicle. You can clean the battery terminals by disconnecting the battery and using a wire brush to get rid of any corrosion. You can also apply baking soda as a solution to clean the terminals. Your car's battery could be at the end of its life and will require replacement. A new battery will supply the proper voltage to your vehicle's spark plugs. This is crucial for a functioning engine. The ignition coil converts low voltage from your battery into high voltage to spark the spark plugs in your car and start the engine. If your ignition coil is not working properly and not functioning properly, it will not be able to spark the plugs. Your engine won't start. The ignition coil can be inspected by checking the engine for a spark or turning the key to see whether it spins. You may have to replace the starter motor as well. If you hear a grating sound when you turn the key in your ignition, it is a sign that the bearings within the starter are starting to wear out. This could be a costly fix, so it's recommended to replace the starter motor as soon as possible if you notice any signs of wear and wear. The replacement of the starter motor is a relatively simple process that requires replacing a few parts and bolts. Alternator The alternator is an appliance 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 malfunctioning. This will allow you to determine if the alternator is causing the battery to drain or your battery is old and should be replaced. When the vehicle is idle the alternator supplies power to the dash lights as well as the radio. It also provides power to the windshield wipers, the power windows, electric steering, heated seats and the power windows. A voltmeter is a tool to check the voltage of your alternator and battery. If your battery's voltage is lower than 6 volts, it should be replaced or charged immediately. A dead or low-volt battery can also stop the starter motor from cranking the engine over and will require more jumper cables to start your car. Before you begin to dismantle the alternator, switch off the ignition and secure all doors. It is also important to disconnect the negative cable from the battery, tuck it away somewhere safe and put on your safety gear. Consult a vehicle's specific repair manual for guidance on how to gain access to the alternator, as well as any other components you'll need to take off. If your vehicle has 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 an alternator's terminal that is marked as WL or IND. Some vehicles, however, have an additional relay for this function. If your warning light does not blink, it's likely that you have an issue that is not related to the one you are experiencing. It is recommended to regularly check your alternator for any indications of a malfunction. While you could perform some of the tests by yourself, you should bring your vehicle into Les Schwab for a free inspection and expert advice. Our technicians can check for corrosion on your battery, battery posts (+ and +) and relays, fuses, as well as voltage output as well as cold starting amps and more. Starter Motor The starter motor is an essential component of the ignition system. It rotates the engine to allow air to be drawn in, which is needed to ignite the fuel. It is typical for the starter motor to be the cause when your car won't turn over. There are many methods of troubleshooting that can be used to assist you in identifying and fixing the issue. When you turn on your car's ignition key, a switch inside the starter engages a pinion-gear that fits into grooves of the flywheel. The pinion gear is then turned the flywheel, which starts the engine. The pinion gear retracts when you release the key to prevent damage. There are a myriad of things that can go wrong in the starter motor, such as an electrical problem in the internal windings, mechanical issues (such as teeth not meshing on the flywheel or pinion gear) or a dead battery. A damaged starter motor could sound like a dead cell phone battery. It can make a clicking sound as it tries to turn the engine over. If the starter motor doesn't work, one of the first things a mechanic would examine is the condition of charge of the battery and its terminals. If the battery is corroded or is low it must be charged or replaced. Depending on how serious the issue is, the mechanic can also test the solenoid using a multimeter. The solenoid is a huge magnetic switch that transmits an electric current from the battery cables that are thick to the starter. This switch connects the bulky cable from the battery to windings in the starter which turns the motor. It also pushes an axis rod to trigger an engaging fork, which causes the pinion to automatically engage with the flywheel. Another option is to disable the ignition switch using the jumper wire. This is an option for a short-term fix, and you should not try it unless sure how to do it. You'll need to be careful to route 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 an electrical current to the starter. However, it is not immune to wear like other parts of the car. The switch can also become stuck in its place or become 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 gets stuck in the ignition, it might be locked. This problem occurs in a variety of vehicles because of a lack oil lubrication. Using a silicone or graphite-based oil on the release pin can aid. Spray some lubricant on the ignition, then move the key. If you're stuck you can try using a hacksaw or piler blade. A problem with the ignition can also lead to other problems. The anti-theft system may not function, or the starter motor may not start when you plug in the key. It could also cause other functions to stop working or cease to function at all. A malfunctioning ignition could cause additional wear and tear on other parts. For instance, if have a heavy keychain, or several items on your keychain, it could strain the ignition switch when you plug it in and accelerate the wear and tear on its internal components. Extreme temperature fluctuations may impact the materials and lubricants in the ignition switch. It is crucial to test the replacement ignition switch prior to assembling the other parts and the steering column. Make sure that the switch is working and that the engine starts without any issues. Make sure that the new ignition switch with the vehicle's model and make. If you're unsure of your ability to install the new ignition switch it could be worth hiring a dealership service shop to do it for you. car key ignition replacement near me can also test and connect other components or replace them.
