How to Fix Car Ignition Problems

The car won't begin until the switch sends an electrical signal to the starter. Normal wear and tear over time could cause the switch to malfunction.

You can remove the trim on your steering column using specially designed tools to gain access to the ignition cylinder module. Consult your repair manual to learn how to do it correctly.

1. Check the Switch

A malfunctioning switch is one of the most frequent ignition problems. It functions as an intermediary between two contacts, controlling the time when relays are activated and deactivated. Since it doesn't transmit the full power of devices such as the starter, it's a lighter component that is less likely to fail. However, it's still possible for the switch to be damaged or corroded.

One sign of a damaged switch is the difficulty in turning the key. This could be due to various factors such as improperly inserting the key, or deteriorating the mechanism over time. It's not unusual to see people mix keys with keys from someone else's. This can result in mechanical damage.

Before contacting a locksmith, you may try a few options. You'll first want to ensure that the battery is fully charged and there are no electrical issues within the system. Also, you should check the voltage of every component to ensure that they are providing enough power. After you've completed these steps, you can begin troubleshooting.

Fortunately, the ignition switch is simple to replace. It's connected to the ignition cylinder, a round module that connects everything. To replace it, you'll need an flathead screwdriver as well as something that is long enough to push the pin inside. This could be anything from an artist's brush to a Kabob skewer, but you should avoid using anything that is brittle and break inside the hole.

Remove any trimming pieces that overhang the switch when you are ready to get started. After this take off and loosen any screws that are holding the switch in place and then gently pull it out. Depending on the model, you may need to disconnect any cables that connect to it. If you have a manual for the vehicle you own it will explain exactly how to do this.

It's best to get the ignition switch replaced by professionals when it's not working. The replacement process involves turning off the steering column, which may trigger unintentional deployment of airbags if done in a wrong manner. For this reason, it's best to have your local locksmith handle this for you.

2. Verify the Wire

If you can't turn the ignition key or your car won't start, your problem could be related to any of the parts of your car ignition lock's ignition system. Understanding how the ignition system works will help you identify problems and make the correct repairs.

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

To determine if the ignition switch is bad or if the ignition coil itself is bad, you need to do a quick electrical test using a voltage meter. When the ignition switch has been running and the voltmeter is reading approximately 12.6, If the voltage drops below that, it means there's an open circuit somewhere in the system. This could be the solenoid, battery, or the ignition coil.

Disconnect the electrical connector from the ignition switch so that no other components interfere with the test. Then set the voltmeter to the resistance or continuity mode and place one lead on one of the ignition switch terminals. The other lead should be connected to the positive terminal of the battery. If the voltmeter reads "open" or doesn't register any voltage, it's time to replace the switch.

When replacing the switch, be certain to use a new ignition cylinder and a good quality key cut to ensure that your vehicle will start and run properly. Also, when replacing the ignition switch, you must be careful not to hit the ignition cylinder pins with your tools, or they'll become stuck and your engine will not start. You'll have to take off the steering wheel as well as the gear selector in certain vehicles to access the ignition cylinder. This can be difficult and shouldn't be done unless you have an owner's manual that indicates it's safe to do this. Otherwise serious damage to the steering column or shifting mechanism is possible.

3. Check the Cylinder

If you've sifted through the wiring, battery, and ignition switch, but cannot get your car to start, it might be time to examine the cylinder. It's the component that holds your key and is mechanically connected to the steering wheel lock to ensure that thieves can't drive the car without the key.

If your cylinder has started to wear out, you could notice that the key won't turn. Sometimes, the pins in the cylinder become stuck when they adjust to the shape of your key, which could cause your car not to start. Alternatively, the cylinder may be shaky however a tap using the small hammer from a tack can aid in releasing it. Be sure not to mix up the springs and ensure that the key is correctly placed.

Another indication that your cylinder is failing is if you have to turn the key and try different positions before it gets started. This is does a new ignition switch require a new key negative sign, and it must be fixed immediately, since it will only get worse over time.

To test the cylinder, you will need to remove the cover on the steering wheel 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 likely possible to take your original ignition switch and cylinder to a locksmith to reuse them, as long as they are in good condition. After replacing the ignition switch and cylinder, ensure that you reconnect the wiring and secure it before reattaching all covers and panels that were removed.

4. Make sure you check the Spark Plugs

The spark plug is the final link in your ignition chain. When it breaks it stops the engine from running. It could be in the form of your car ignition switch repair not starting at all, or may start but run poorly. In either of these scenarios, it's likely that one of several things are preventing or impeding electricity from jumping across spark plug gaps, which then ignites the fuel mixture and air inside your engine.

Before you begin working on your spark plugs, make sure that you work on a safe surface and employing protective gloves and tools to avoid being struck. Spark plugs can get very hot and can cause serious injuries if handled with hands that are not protected.

If a spark plug goes bad, you may notice that the tip of the central electrode has some light brown or gray substance on it. The electrode may also have a dark coating. These deposits, or fouling, may prevent high-voltage electricity from crossing the spark plug gap and igniting your engine.

If you suspect that your spark plugs might be the culprit you could test them by remove the plugs from their tube inside the ignition coil. This can be done by disconnecting the coil as well as the plug wire. After that, you'll need to follow the correct procedure for your car ignition barrel replacement Near me to remove the components that cover the plugs. After you have removed the plugs, place them on a metal surface that is grounded and begin the engine. If they're functioning, you should be able to see a strong blue spark at the tip of central electrode.

If you don't see a spark, you've discovered the problem. The next step is to go backwards through the chain of ignition and check each component until the spark plugs aren't functioning. All systems will wear out and eventually fail, and this is particularly relevant to ignition systems. Regular maintenance can slow down the process and avoid a major headache at the worst time.
