How to Fix Car Ignition Switch Problems

If your vehicle starts and runs but the ignition switch doesn't turn over the spark plugs, there may be a myriad of reasons for this. Some are easy and cheap to fix, while others require specialized tools and assistance from an expert mechanic.

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

Battery

It could be that your battery is dead when your car isn't starting. This is a common issue that can be fixed by a jump or charging of the battery. If this doesn't solve the issue your ignition switch could be defective. This component carries battery power to other electrical components, such as the starter motor and ignition coil. If the ignition switch is defective, it will not allow current to pass through and the engine will not start.

The battery is the primary source of electrical energy in your vehicle. It's a black, insulated box with positive (+) and negative (-) terminals on the top. The terminals may be corroded and stop the battery from providing electricity to the rest of the vehicle. You can clean the battery's terminals by disconnection of the battery and using a wire brush to eliminate any corrosion. You can also apply a baking soda solution to clean the terminals.

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

The ignition coil converts the battery's low voltage into high voltage, which causes it to ignite the spark plugs inside your car and then start the engine. If the ignition coil is damaged it won't be able to spark the plugs. Your engine won't start. You can test the ignition coil by looking for a spark in the engine or turning the key and observing if the engine turns over.

You might also have to replace your starter motor. If you hear a grinding sound when you turn your ignition key it is a sign that the starter bearings are wearing out. It is a costly repair, so it is recommended to replace your starter motor immediately if you detect signs of wear. The replacement of the starter motor is a relatively simple process that requires the replacement of a few parts and bolts.

Alternator

The alternator is the one that charges your battery and powers the electrical parts of your car while the engine is running. If you suspect that there is a problem with your alternator, you should first test the battery. This will allow you to determine if your alternator is draining the battery or if your battery is old and needs replacement.

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

Before you begin removing the alternator, ensure that the lost ignition key is off and all the doors are locked. Unplug the negative cable and store it safely. Wear safety equipment. Check out a specific vehicle repair manual for guidance on how to gain access to the alternator and any other parts you need to remove.

After you've removed the belt, if your car ignition barrel replacement has one remove the warning light wire from the back of the alternator. The wire will connect directly to an alternator terminal identified WL or IN. Certain vehicles, however, have an additional relay for this purpose. 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.

You should regularly inspect your alternator for any indications of a malfunction. You can do some of these checks yourself, but it's best to bring your car into Les Schwab so that they can examine it and give you expert advice. Our technicians can check for corrosion on your battery posts, battery (+ and +), fuses, relays as well as voltage output and cold starting amps and many more.

Starter Motor

The starter motor is a crucial component of the lost ignition key system. It turns the engine over so that air can be drawn in and ignite the fuel. It is common that the starter motor will be the cause when your car won't turn over. There are many methods of troubleshooting that can aid in diagnosing and fixing the issue.

When you turn on your vehicle'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 begins the engine. The pinion gear retracts when you release the key to prevent damage.

The starter motor can be affected by a number of things, including mechanical issues (such as teeth not lining up on the flywheel) or dead cells. A defective starter motor can sound like a dead battery; it'll make a click when it attempts to turn over the engine, but won't.

The state of charge and the battery's terminals will be checked by a mechanic if the starter motor doesn't work. If the battery has corrosion or is low it needs to be recharged or replaced.

Depending on the extent of the problem, the mechanic may also test the starter solenoid with a multimeter. The solenoid is a massive magnet switch, transmits an energy surge from the long battery cables to the starter. This switch essentially connects the long battery cable to the windings inside the starter that actually make the electric motor turn and also pushes a rod that actuates an engaging fork which is then pushed by the gear pinion to automatically engage with the flywheel.

Another option is to bypass the ignition switch by using a jumper wire. This is only a temporary solution but it shouldn't be recommended unless you're able to perform it correctly. You'll need to be careful about routing the jumper wire to battery terminals and make sure the switch is set to the "Start" position.

Ignition Switch

The ignition switch is the place where you insert your key into the car. It is used to start the engine and send electrical current to the starter. However it isn't immune to wear like other parts of the car ignition Locksmith. The switch may also get stuck in its slot or become locked. It is important to regularly check it for issues so you can take action before the car doesn't start.

If your key is a struggle to turn or gets stuck in the ignition, it might be locked. This is a common problem for a variety of vehicles and occurs because of a lack of lubrication. Using a silicone or graphite-based oil on the release pin can help. Spray some lubricant into the ignition, and then move the key. If it's still stuck employ a piler or hacksaw blade to assist in moving it.

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

A failing ignition switch can cause a lot of extra wear and tear on other parts. For instance, if you have a large keychain, or several items on your keychain it can strain the ignition switch when you insert it in, and could increase the wear on its internal components. Extreme temperature fluctuations may affect the materials and lubricants used in the ignition switch.

It's important to test the new ignition switch prior to reassembling other components and the steering column. Make sure that the new ignition switch works and that your engine starts smoothly. Make sure that the new ignition switch with the vehicle's model and make. It might be worth it to hire a dealership to install the ignition switch for you if you aren't confident in your ability to install it. They can also test and connect any other parts or replace them.
