How to Fix Car Ignition Switch Problems

There are a myriad of reasons your car ignition replacement might start and run but the ignition fails to start the spark plugs. Some are easy and cheap to fix, while others require special tools and assistance from a mechanic.

First, 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 loose springs or obstructions.

Battery

If your car won't start it could be because your battery is dead. This is a common problem which can be resolved by an extra jump or charging the battery. If this doesn't solve the problem your ignition switch could be bad. This component carries battery power to other electrical components, like 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 begin.

The battery is the source of all the electrical energy in your car. The battery is a black box with positive (+) and negative (-) terminals on the top. The terminals can be corroded, preventing the battery from supplying power to the rest the vehicle. By disconnecting the battery you can employ a wire bristle remove any corrosion. You can also clean the terminals with baking soda as a solution.

It is also possible that your car's battery has just reached the end of its lifespan and is in need of replacement. A new battery will provide the correct voltage to the spark plugs in your vehicle, which is required to ensure that your engine is running properly.

The ignition coil converts the battery's low voltage into high voltage that causes the spark plugs inside your car and then start the engine. If the ignition coil is faulty, it won't be capable of sparking the plugs, and your engine will not start. You can test the ignition cylinder lock repair coil by checking whether there is a spark in the engine or turning the key to see if the engine turns over.

You may need to replace the starter motor too. If you hear a grinding sound as you turn the ignition key, this means that the starter bearings are worn out. It can be an expensive repair so it is best to replace your starter motor when you begin to detect signs of wear. It's an easy process that involves replacing the bolts and a few components.

Alternator

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

Your car's alternator also provides power for the dashboard lights, windshield wipers, power windows, electric steering, heated seats and your radio while the vehicle is idle. You can use a voltmeter to check your battery and the alternator for proper voltage levels. 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 and will require additional jumper cables to start your car.

Before you begin removing the alternator, switch off the ignition and secure all doors. Disconnect the negative cable and store it in a safe place. Wear safety equipment. Refer to a vehicle specific repair manual for instructions on how to access the alternator and any other components you require to take off.

Once you've removed the belt, if your vehicle is equipped with one remove the warning light wire from the back of the alternator. This will usually connect directly to the alternator's terminal that is marked as WL or IND. Some vehicles, however have a separate relay for this function. If your warning light doesn't blink, you may suspect a different problem.

The alternator is a crucial component of your vehicle, and it is important to check it frequently to look for signs of problems. You can do certain of these tests by yourself, however it is best to bring your car to Les Schwab so that they can inspect it and give you expert advice. Our technicians can test for corrosion on your battery posts, battery (+ and +) and relays, fuses, and voltage output as well as cold starting amps and many more.

Starter Motor

The starter motor is a crucial component in the ignition system. It turns the engine to allow air to be sucked in, which is needed to ignite the fuel. It is common that the starter motor will be at fault when your car doesn't turn. There are a few troubleshooting methods that can help you diagnose the issue and fix it.

When you turn the key in your vehicle's ignition, a switch on the starter is activated by the pinion gear, which fits into grooves on the flywheel. The pinion gear then turns the flywheel, which then begins the engine. The gear retracts once you release the key to prevent damage.

There are a variety of things that could cause problems with the starter motor including an electrical failure in the internal windings, mechanical issues (such as teeth no longer meshing on the flywheel or pinion gear) or a dead battery. A malfunctioning starter motor may sound like a dead phone battery. It will make a clunk sound as it tries but cannot turn the engine over.

If the starter motor doesn't work One of the first things a mechanic would check is the state of charge on the battery and its terminals. If the battery is depleted or has rust on its terminals, it will require charging or replaced.

Depending on the degree of the problem, the mechanic may also test the starter solenoid with a multimeter. The solenoid, which is a large magnet switch, transmits an energy surge from the thick batteries cables to the starter. This switch connects the bulky cable from the battery to the starter's windings which turns the motor. It also pulls a rod to actuate an engaging fork which pushes the pinion to automatically engage with the flywheel.

A jumper wire can be used to disable the ignition. This is only a temporary solution however it shouldn't be a recommendation unless you're able to perform it correctly. You'll need to carefully route the jumper wire to battery terminals and make sure the switch is in the "Start" position.

ignition key replacement Switch

The ignition switch is the place where you insert your car keys. This allows the system to enable electrical flow to your starter and then start the engine, however it isn't immune to wear and tear as other car components. The switch may also become stuck in its slot or locked. You should check for problems regularly so you can act before your car doesn't start.

It could be locked if your key is difficult to turn or becomes stuck in the ignition. This is a common problem for many vehicles and is due to a lack of lubrication. Using a graphite or silicone-based oil on the release pin can help. Spray a little into the ignition, and then try moving the key. If it's still stuck, use 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 may stop working or the starter motor might not turn on when you put the key. It could also cause other functions to stop working or cease to function at all.

A failing ignition switch can also leave you with lots of wear and tear on other parts. If you own a keychain with multiple items or a heavy one, this could cause strain on the ignition switch and increase wear on the internal components. Extreme temperature fluctuations may impact the materials and lubricants used in the ignition switch.

Once you have a replacement ignition switch, it's important to test it prior reassembling the steering column and other parts. Make sure the replacement ignition switch works and that your engine starts smoothly. It is also important to confirm that the new ignition switch is compatible with your vehicle's model and model. It might be worth it to have a dealership install the ignition switch for you if you aren't sure about your ability to do so. They can also test the replacement and install any other parts that require connecting or replaced.
