How to Fix Car Ignition Problems

The car ignition locked won't start until the switch sends an electrical signal to the starter. Over time wear and tear can cause the switch to malfunction.

With the help of specialized tools, you are able to remove the trim on your steering column and gain access to the ignition cylinder module. Refer to your repair ignition lock cylinder manual for learn how to do it correctly.

1. Make sure you check the Switch

A malfunctioning switch is one of the most frequently encountered ignition issues. It regulates the time when relays are activated and deactivated through the use of a bridge. Because it doesn't channel the full power of devices like the starter, it's a less powerful component that's less likely to fail. However, it's still possible for the switch to get damaged or corroded.

A malfunctioning switch is identified by a difficult time turning the key. This could be due to various factors such as improperly inserting the key, or the mechanism wearing out over time. It's not unusual for people to mix their keys up with those of others. This can result in mechanical damage.

Before calling 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 in the system. It is also important to verify the voltage of every component to ensure that they are providing enough power. After you've completed these steps, it's now time to begin troubleshooting.

The ignition switch is simple to replace. It is connected to the ignition module, a round component that connects everything. To replace it, you'll need a flathead screwdriver, and something that is long enough to push the pin into. This can be anything from a paintbrush handle to a kabob skewer, but you should stay clear of anything brittle that could break inside the hole.

Remove any trim pieces that are covering the area around the switch once you're ready to work. After taking off the trim pieces, remove any screws holding the switch in place. Then carefully take it off. Depending on the model, you may also have to unplug any wires that connect to it. You can learn how to do this in the manual of your vehicle.

If the ignition switch isn't functioning it is recommended to have it replaced by professionals. It can be difficult to replace the ignition switch, without disabling your steering column. This could result in the unintentional airbag being deployed if you do it incorrectly. This is why it's best to have the auto locksmith ignition replacement in your area handle this for you.

2. Verify the Wire

Your car might not start if you are unable to turn the key or if it isn't starting. This could be due to a number of components within the ignition key replacement system. It is important to know how the ignition system works so that you can pinpoint problems and make the right repairs.

The ignition switch is an electric switch that has multiple poles and is operated by the key. It has four positions, which include "off", "accessory", "run" and the "lock". If the switch is in the lock position (which usually has an indicator in red), the ignition circuit is live and it's impossible to start the engine.

To determine whether the ignition switch damaged or the ignition coil is defective, you will need to do a quick electrical test with the help of a voltmeter. When the ignition cylinder lock repair switch is set to run at a certain voltage, the voltmeter should read about 12.6, If the voltage falls below that it indicates that there is an open circuit within the system. This could be at the solenoid, the battery or at the ignition coil itself.

Disconnect the electrical connector so that it doesn't interfere with the test. Then, set the voltmeter to the continuity or resistance mode and place one lead on one of the ignition switch's terminals. The other lead should be connected to the positive terminal of the battery. If the voltmeter is "open" or fails to show any voltage, you should replace the switch.

When replacing the switch, be certain to use a new ignition cylinder as well as a high quality key cut to ensure that your vehicle will start and run correctly. Also, when replacing the ignition switch, be careful not to strike the pins of the ignition cylinder with your tools or they'll become stuck and your engine won't be able to start. In certain vehicles, you'll need to remove the steering column and gear selector in order to access the ignition cylinder. This isn't easy and is not recommended unless you have an owner's guideline that says that it is safe to do so. If you don't, it is possible to cause serious damage to your steering column and shift mechanism.

3. Check the Cylinder

If you've sifted through the wiring, battery and ignition switch and still can't get your car to start, it could be time to examine the cylinder. It's the part that holds your key and is mechanically connected to the lock on the steering wheel so a would-be thief can't steer the car without the key.

You may notice that your key will not turn if the cylinder has worn out. The pins in the cylinder can get stuck as they adapt to the shape of your key. This could cause your vehicle to not start. The cylinder might also be sloppy. A tap using the tackhammer can aid. Be careful not mixing the springs, and ensure that your key is correctly placed.

Another indication that your cylinder is in trouble is if you have to move the key around and try different positions before it begins. This is a sign of trouble, and it must be addressed immediately, since it will only get worse with time.

To check 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 metal ignition cylinder. If you don't have an extra ignition switch lying around, it's likely possible that you can take your original ignition switch and the cylinder to a locksmith in order to reuse them as long as they are in good condition. After replacing the switch and cylinder, make sure you connect the wiring harness and secure it and reattach any covers, or panels you removed.

4. Check the Spark Plugs

The spark plug is the ignition system's last link. When it breaks, the engine can't run. This could take the form of your car not running at all, or it could start but then run poorly. In either case, the reason is likely to be one of a few factors that block or hinder electricity from crossing the spark plug gap which allows your engine's gas and fuel mixture to run.

Make sure you wear protective tools and gloves before working with your spark plugs. Spark plugs can get very hot and cause serious injuries if they are handled with hands that are not protected.

When a spark plug is bad, you might observe that the edge of the central electrode is covered with a slight brown or gray substance on it. The electrode may also have an opaque coating. These deposits, or fouling, can stop high-voltage electrical current from crossing the spark plug gap and igniting your engine.

If you believe that your spark plugs could be at fault you can test them by removing them from their tube inside the ignition coil. You can do this by disconnecting the coil from the plug wire, and following the proper procedure for your vehicle to remove the components that cover the spark plugs. Once you have removed the plugs you can place them on a surface that is grounded and crank the engine. If they're good, you should see a strong blue spark extending across the gap in the middle of the central electrode.

If you don't see a spark, you've found the issue. The next step is to go backwards through the chain of ignition and test each component until the spark plugs stop working. All systems will get older and eventually break, and this is particularly applicable to ignition systems. Regular maintenance can reduce the wear and tear and prevent an issue in the worst case.
