20 Questions You Should Ask About Fix Car Ignition Before You Buy Fix Car Ignition

How to Fix Car Ignition Problems

The car won't begin to start until the ignition switch transmits an electrical signal to the starter motor. Normal wear and tear over time can cause the switch to malfunction.

Using specialized tools, you can remove your steering column trim and gain access to the ignition cylinder module. Consult your repair manual for instructions on how to do this in a safe manner.

1. Check the Switch

A defective switch is one of the most frequent ignition problems. It regulates when relays are activated and deactivated through the use of a bridge. It is less likely to fail because it doesn't channel full power from devices like the starter. However, it's still possible for the switch to become damaged or corroded.

A defective switch can be identified by a difficult time turning the key. This could be due to a variety of things such as not inserting the key correctly or the mechanism wearing out over time. It's also common for people to mix up their car keys with the keys of someone else, which can cause mechanical damage.

Before contacting a locksmith, you can try a few things. You'll first want to ensure that the battery is fully charged and there are no electrical issues within the system. You should also check the voltage of each component to determine if it's supplying adequate power. After you've completed these steps, you'll be able to begin troubleshooting.

Luckily, the ignition switch is pretty simple to replace. It's connected to the ignition cylinder, a round module that holds everything together. You'll need to use a flathead and a piece of material long enough to push the pin into. This can be anything from an artist's brush to a kabob skewer, but you should stay clear of anything brittle that could break inside the hole.

Remove any trimming pieces that are covering the area around the switch when you are ready to work. Once you've done this take off and loosen any screws that keep the switch in place, and then gently pull it out. Depending on the model, you might need to disconnect any cables connected to it. If you have a manual for your vehicle it will explain exactly how to do this.

It is recommended to have the ignition switch replaced by professionals if it doesn't work. It's difficult to replace the ignition switch without removing the steering column. This could lead to an accidental airbag deployment when you don't do it correctly. It's best to let your local locksmith handle this.

2. Check the Wire

The car may not start if you cannot turn the key or it will not start. This could be due a number components in the ignition system. Understanding how the ignition system works can help you spot problems and make the appropriate repairs.

The ignition switch is a low-voltage multi-pole electrical switch which is turned by the key. It has four positions including off, accessory, run and "lock." If car ignition switch repair is in the lock position (which usually has the red indicator), the ignition circuit is active and it's not possible to start the engine.

You can use a voltmeter quickly test the ignition switch and ignition coil. If the ignition switch is running and the voltmeter is reading around 12.6, If the voltage drops below that, it means there's an open circuit somewhere within the system. This could be at the solenoid, the battery or the ignition coil itself.

Connect the electrical connector to the ignition switch to ensure that there are no other components that could interfere with the test. Set the voltmeter to the resistance or continuity modes and place one lead on one of the terminals of the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltmeter reads "open" or does not register any voltage it's time to replace the switch.

Make sure you use a new ignition key and high-quality ignition cylinder when replacing the switch to ensure your vehicle is running and starts correctly. Also, when replacing the ignition switch, you must be careful not to hit the pins of the ignition cylinder with your tools or they'll get stuck and your engine will not start. In some vehicles, you'll have to remove the steering column and the gear selector to get access to the ignition cylinder. This can be difficult and should not be done unless you have an owner's guideline that says it's safe to do this. If you do not, it is possible to cause irreparable damage to your steering column and the shift mechanism.

3. Check the Cylinder

If you have tried the battery, the wiring, and the ignition switch but you are still unable to start your car It could be time to check the cylinder. The cylinder is the component that holds the key and is mechanically attached to the steering lock to ensure that thieves can't drive the car if it's not there.

You may be noticing that your key does not rotate if the cylinder is worn out. Sometimes, the pins within the cylinder become stuck as they adapt to the shape of your key, which could cause your car not to start. The cylinder may also be sloppy. Tapping it with the tackhammer can aid. Be careful not to crush the springs within and make sure that your key is correctly inserted before tapping.

If you are required to jiggle and move your key around before it will begin, it is a sign that your cylinder has been damaged. This is a sign of trouble and should be addressed immediately, since it will only get worse with time.

To examine the cylinder, you must remove the steering wheel cover and disconnect the battery. The old ignition switch should be easy to remove, as should the cylinder made of steel. If you don't have an extra ignition switch lying around, it's possible to take your original ignition switch and cylinder to a locksmith to reuse them as long as they're in good condition. After replacing the switch and cylinder be sure to reconnect the wiring harness and secure it and then reattach any covers or panels you removed.

4. Check the Spark Plugs

The spark plug is the final link in your ignition chain. If it fails it will stop the engine from running. This could take the form of your car not running at all, or it could start but not run well. In either of these scenarios, it's likely that one of several factors are hindering or blocking electrical current from crossing spark plug gaps, which in turn ignites the mixture of fuel and air inside your engine.

Be sure to use protective tools and gloves before you begin working with your spark plugs. Spark plugs can be extremely hot and can cause serious injuries if handled with hands that are not protected.

When a spark plug is bad, you might observe that the edge of the electrode's central portion has some light brown or gray substance on it. It may also have a black coating on the opposite side of the electrode. These deposits, also known as fouling, can stop high-voltage electricity from crossing the spark plug gap and sparking your engine.

If you believe that your spark plugs may be at fault you can test them by taking the plugs from their tube in the ignition coil. This can be done by disconnecting the coil from the plug wire, and following the proper procedure for your car to remove the components that cover the spark plugs. After you have removed the plugs, place them on a metal surface that is grounded, and start the engine. If they are working you will see an intense blue spark at the point of the central electrode.

If you don't see a spark, you've identified the issue. Next, you'll need to go backwards through your ignition chain and check each component until the spark plugs stop working. Every system will get older and eventually break This is especially applicable to ignition systems. But, regular maintenance can help reduce the wear and tear and avoid a big headache at the worst moment.
