The 9 Things Your Parents Taught You About Fix Car Ignition

How to Fix Car Ignition Problems

The car ignition switch repair won't start until the ignition switch sends the electrical signal to the starter motor. Over time wear and tear may cause the switch to malfunction.

You can remove the steering column trim using specialized tools to gain access to your ignition cylinder module. Refer to the repair manual to get guidance on how to do this properly.

1. Make sure you check the Switch

One of the most frequent ignition problems is a bad switch. It acts as a bridge between two contacts, and controls when relays activate and deactivate. Because it isn't able to transmit the full power of devices like the starter, it's a lighter component that's less likely fail. It is still susceptible to being damaged or corroded.

One sign of a damaged switch is a difficulty turning the key. This can be due to a number of factors that include incorrectly inserting a key or deteriorating the mechanism 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. First, ensure that the battery is fully charged and there are no other electrical issues that could be affecting the system. Also, you should test the voltage of each component to see if they're capable of supplying enough power. Once you've done these steps, you're ready to start troubleshooting.

The ignition switch is simple to replace. It's connected to the ignition cylinder, which is a round module that holds everything together. To replace it, you'll require an flathead screwdriver as well as something that is long enough to push the pin inside. It could be anything from a paintbrush handle to a Kabob skewer, but you should stay clear of anything that is brittle and break inside the hole.

Remove any trim pieces that overhang the switch when you are ready to go. After that, loosen and remove any screws that are holding the switch in place then carefully pull it out. Depending on the model, you might also need to disconnect the wires that connect to it. You can learn how to do it in the manual of your vehicle.

If the ignition switch isn't functioning, it's best to have it replaced by a professional. Replacing it can involve disabling the steering column which could trigger an unintentional airbag deployment if it's done in a wrong manner. It's best to allow your locksmith to take care of this.

2. Verify the Wire

If you can't turn the key in the ignition lock repair or your car won't start, your issue could be due to any number of components of your vehicle's ignition system. Understanding how the ignition system works will help you identify problems and make the correct repairs.

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

To determine if the ignition switch is damaged or the auto ignition key replacement coil is faulty, you'll must conduct a quick electrical test with the help of a voltage meter. The voltmeter should read around 12.6 volts when the ignition switch is in the run position. If the voltage falls below that, it indicates there's an open circuit somewhere within the system. This could be the solenoid, battery, or the ignition coil.

Connect the electrical connector to the ignition lock repair near me switch so that no other components interfere with your test. Set the voltmeter in the continuity or resistance modes and place one lead onto one of the terminals on the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltmeter reads "open" or does not show any voltage, you should replace the switch.

When replacing the switch, be sure to use a new ignition cylinder and a top quality key cut to ensure that your car will start and run correctly. When replacing the ignition switch, you must be careful not to hit the cylinder's pins on the ignition with your tools, or they'll get stuck and your engine will not start. In certain vehicles, you'll need to remove the steering column and the gear selector to get access to the ignition cylinder. This can be difficult and isn't recommended until you have a vehicle's owner's manual that states it's safe. Otherwise serious damage to the steering column or shifting mechanism is likely.

3. Check the Cylinder

If you have tried the battery, the wiring, and the ignition switch, but still cannot get your car ignition switch repair to start, it may be time to inspect the cylinder. The cylinder is the component which holds the key and is mechanically connected to the steering lock to ensure that burglars won't be able to drive the car without it.

If your cylinder has started to wear out, you might find that the key doesn't turn. The pins of the cylinder can get stuck when they adapt to your key's shape. This could cause your vehicle to not start. Alternatively, the cylinder may be loose, but a tap with a small tack hammer can aid in releasing it. Be careful not to crush the springs within and make sure that your key is properly placed before tapping.

If you are required to jiggle and move the key before it can start, this is another indication that your cylinder has gone bad. This is a negative sign, and it must be addressed immediately as it will only worsen over time.

To test the cylinder, you'll need to take off the steering wheel cover and disconnect the battery. You'll then be able to pull out the old ignition switch as well as the cylinder made of metal. If you don't own an extra switch, you may be able take your original ignition cylinder and switch to locksmiths for reuse as long they're in good shape. After replacing the switch and cylinder, ensure that you reconnect the wiring harness, secure it in place and then reattach any covers or panels you've removed.

4. Check the Spark Plugs

The spark plug is the last link in your ignition chain. The engine cannot start in the event that the spark plug fails. This could take the form of your car not running at all, or it may start but run poorly. In any case, the root is likely to be one of the factors that block or hinder electricity from jumping across the spark plug gap which ignites your engine's air and fuel mixture to start.

Be sure to use gloves and protective tools before you begin working with your spark plugs. Spark plugs are hot and could cause serious injury if you touch them with your naked skin.

If a spark plug goes bad, you might observe that the edge of the central electrode has some light brown or gray residue on it. It may also have a black layer on the sides of the electrode. These deposits or fouling can prevent high-voltage electrical current from crossing the gap between your spark plug, igniting an engine.

If you suspect your spark plugs might be the cause you can test them if you remove them from the tube that is inside the ignition coil. This can be done by disconnecting the coil and the plug wire. Then, you will have to follow the proper procedure for your vehicle to remove the components that cover the plugs. After removing the plugs place them on a surface that is grounded, and start the engine. If they are good you will see a bright blue spark extending across the gap between the tip of the central electrode.

If you don't see any spark, you've found the problem. The next step is to go backwards through the chain of ignition and test each component until the spark plugs are no longer functioning. It's important to remember that all systems wear down and break over time and this is particularly applicable to ignition systems. That said, routine maintenance can help slow the process down and avoid a major headache at the worst possible time.
