How to Fix Car Ignition Problems

A car ignition lock won't start unless the ignition switch sends the electrical signal to the starter motor. Over time, normal wear and tear could cause the switch to malfunction.

You can remove the steering column trim with specialized tools to access the ignition cylinder module. Check out your repair manual to learn how to do it right.

1. Make sure you check the Switch

A bad switch is among the most frequently encountered ignition issues. It functions as an intermediary between two contacts, and controls the relays' activation and Fix Car Ignition deactivation. It is less likely to fail due to the fact that it doesn't channel full power of devices like the starter. However it's still possible for the switch to become damaged or damaged or corroded.

One indication of a defective switch is difficulty turning the key. This can be caused by many things such as incorrectly inserting the key or deteriorating the mechanism over time. It's not unusual to see people mix their keys up with someone else's. This could cause mechanical damage.

Before contacting a locksmith, you may try a few options. First, make sure that the battery is fully charged and there aren't any electrical issues in the system. It is also important to check the voltage of each component to determine if they're capable of supplying enough power. After you've completed these steps, it's now time to start troubleshooting.

Luckily, the ignition switch is simple to replace. It is connected to the ignition module, which is a round piece of metal that connects everything. To replace it, you'll require an flathead screwdriver as well as something long enough to press the pin inside. This can be anything from paintbrush handles to Kabob skewer, but you should stay clear of any brittle material that could break inside the hole.

Remove any trim pieces that are covering the area around the switch when you are ready to get started. After taking off the trim pieces, remove any screws that are holding the switch in position. Then carefully pull it out. Depending on the model, you may also need to disconnect any wires connected to it. If you have a manual for the vehicle you own it will explain exactly how to do this.

If the ignition switch isn't functioning it is recommended to have it replaced by professionals. It is possible to replace it by turning off the steering column, which could trigger an unintentional airbag deployment if done in a wrong manner. It is recommended to let your local locksmith handle this.

2. Check the Wiring

If you are unable to turn the ignition key or Fix Car Ignition your car isn't starting, your issue could be related to any of the components of your vehicle's ignition system. It's crucial to understand how the ignition system functions to be able to spot issues and make the appropriate repairs.

The ignition switch is a low voltage multi-pole electrical switch which is operated by a key. It has four positions: off, accessory, run and "lock." When the switch is locked (which is usually marked by an red light) the ignition circuit is in operation and it is inaccessible to start your vehicle.

You can use a voltage meter to quickly test the ignition switch or coil. The voltmeter should read around 12.6 volts when the ignition switch is in the running position. If the voltage falls below that, it means there's an open circuit somewhere in the system. This could be at the solenoid, the battery or at the ignition coil itself.

Connect the electrical connector to the ignition switch so that there are no other components that could interfere with your test. Then you should set the voltmeter in the continuity or resistance mode and put one lead on 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, it is recommended to replace the switch.

Use a new ignition key and a top-quality ignition cylinder when replacing the switch to ensure your vehicle starts and runs correctly. When you replace the switch, ensure not to touch the pins of the ignition cylinder with your tools. Otherwise, they will get stuck and the engine will not run. You'll have to take off the steering wheel as well as the gear selector on some vehicles to access the ignition cylinder. This isn't easy and shouldn't be done unless you have an owner's manual that indicates it's safe to do so. If you do not, it is possible to cause serious 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 still can't start your car It could be time to check the cylinder. The cylinder is the component that holds the key. It is mechanically attached to the steering lock to ensure that a would-be burglar can't drive the car without it.

You may notice that your key will not turn if the cylinder has worn out. The pins in the cylinder may become stuck as they adapt to your key's shape. This could cause your vehicle to not start. The cylinder could also be loose. A tap using a small tackhammer will aid. Be careful not to disturb the springs inside and ensure that the key is correctly placed before tapping.

If you are required to move the key before it will begin, it is a indication that your cylinder is been damaged. This is a negative sign, and it must be addressed immediately, since it will only get worse with time.

To examine the cylinder you'll need to unplug your battery and take off the cover around your steering wheel until you are able to access the ignition module. The old ignition switch should be easy to remove, as well as the metal ignition cylinder. If you don't have a spare switch, you might be able to take your original ignition cylinder as well as switch to a locksmith for reuse as long as they're in good condition. After replacing the switch and cylinder, ensure that you reconnect the wiring harness, secure it in place and reattach any covers, or panels that you have removed.

4. Check the Spark Plugs

The spark plug is the ignition system's last link. The engine won't start when the spark plug is broken. It can be that your car won't start at all or it will run poorly. In either case, the cause is likely to be one of several things that prevent or impair the flow of electricity across the spark plug gap, which causes your engine's air and fuel mixture.

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

When a spark plug is bad, you may notice that the tip of the central electrode is covered with a slight brown or gray substance on it. The electrode could also have a dark coating. These deposits, or fouling, may prevent high-voltage electricity from crossing the spark plug gap and sparking your engine.

If you think that your spark plugs could be at fault you can test them by taking them from their tube inside the ignition coil. You can do this by disconnecting the coil from the plug wire and following the correct procedure for your vehicle to remove the components that cover the spark plugs. After you have removed the plugs, you can place them on a surface that is grounded and crank the engine. If they are working you should see an intense blue spark near the edge of the central electrode.

If you don't see a spark, you have found the issue. The next step is to go backwards through your ignition chain and test each part until the spark plugs are no longer working. Every system will wear out and eventually break and this is especially relevant to ignition systems. Routine maintenance can help to reduce the wear and tear and avoid major problems at the worst time.
