How to Fix Car Ignition Problems

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

With the help of special tools, you can remove the trim on your steering column and gain access to the ignition cylinder module. Refer to your repair manual for guidance on how to do this properly.

1. Check the Switch

A defective switch is among the most frequent ignition problems. It controls the moment relays are activated, and deactivated, acting as bridge. Because it isn't able to harness the full power of devices like the starter, it's a lighter component that's less likely to fail. The switch could still be damaged or corroded.

One indication of a defective switch is a difficulty turning the key. This could be due to various factors, including incorrectly inserting the key or the mechanism wearing out over time. It's not uncommon to see people confuse their keys with someone else's. This can result in mechanical damage.

If the switch isn't functioning there are a few things you can try before calling a locksmith. You'll first want to ensure that the battery is fully charged and that there are no electrical issues in the system. You should also check the voltage of every component to make sure they're providing enough power. Once you've completed these steps, you're ready to begin troubleshooting.

The ignition switch is easy to replace. It's connected to the ignition cylinder, a round module that connects everything. To replace it, you'll require a flathead screwdriver, and something long enough to push the pin inside. You can employ anything from a paintbrush, to a Kabob stick, but be careful of anything that is brittle, as it can cause damage to the hole.

Remove any trimming pieces that overhang the switch when you are ready to get started. Once you've done this remove and loosen the screws that hold the switch in place then gently remove it. Depending on the model you may have to cut off any cables connected to it. You can learn how to do this in the manual of your vehicle.

It is recommended to have the ignition switch replaced by professionals if it doesn't work. The replacement process involves turning off the steering column, which could result in unintentional airbag deployment if it's done incorrectly. For this reason, it's often best to have your local locksmith handle this for you.

2. Check the Wiring

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

The ignition switch is a low-voltage multi-pole electrical switch which is turned by the key. It has four positions including off run, accessory, and "lock." If the switch is in the lock position (which typically has an indicator in red), the ignition circuit is active and it's impossible to start the engine.

To determine whether the ignition switch is damaged or if the ignition coil itself is bad, you have to conduct an electrical test with an Voltmeter. The voltmeter should read approximately 12.6 volts when the ignition switch is in the run position. If the voltage is below that, there is an open circuit somewhere within the system. This could be at the solenoid, the battery or the ignition coil itself.

Remove the electrical connector from the ignition switch so that no other components can interfere with your test. Set the voltmeter to the resistance or continuity modes and place 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 register any voltage, you should replace the switch.

Use a brand new ignition key and high-quality ignition cylinder when replacing the switch to ensure your vehicle starts and runs correctly. Also, when replacing the ignition switch, be careful not to hit the ignition cylinder pins with your tools, or they'll get stuck and your engine will not start. https://www.g28carkeys.co.uk/car-ignition-lock-repair-near-me/ 'll need to remove the steering wheel and the gear selector in some vehicles to gain access to the ignition cylinder. This isn't easy and is not recommended unless you have an owner's guideline that says it's safe to do so. If you don't, it is possible to cause irreparable damage to your steering column and the shift mechanism.

3. Check the Cylinder

If you've gone through the battery, wiring and ignition switch and still cannot get your car to start, it could be time to look at the cylinder. It's the part that holds your key and is connected to the steering wheel lock so a would-be thief can't control the car without keys.

If your cylinder has started to wear out, you may notice that the key won't turn. Sometimes, the pins inside the cylinder are stuck as they adapt to the shape of the key, which could cause your car to not start. The cylinder could also be loose and a tap using a small tack hammer can assist in releasing it. Be careful not to disturb the springs inside and ensure that your key is correctly installed prior to tapping.

If you are required to move the key around before it will begin, it is a indication that your cylinder is been damaged. This is a negative sign, and it should be corrected right away, since it will only get worse over time.

To examine the cylinder you'll need to disconnect your battery and remove the cover on your steering wheel until you are able to access the ignition module. You'll then be able pull out the old ignition switch and the cylinder made of metal. If you don't have an additional ignition switch around, it's possible that you can take your original ignition switch and the cylinder to a locksmith and reuse them, as long as they are 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 you've removed.

4. Check the Spark Plugs

The spark plug is the final link in your ignition chain. The engine cannot start in the event that the spark plug fails. It could be that your vehicle won't start at all or it will run badly. In either case, it is likely that one or more things are hindering or preventing electrical current from crossing spark plug gaps, which ignites the air and fuel mixture inside your engine.

Before you begin working on your spark plugs, be sure that you are working on a safe surface and employing protective gloves and tools to prevent getting hit with. Spark plugs are hot and could cause serious injuries when touched with your naked skin.

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

If you suspect that your spark plugs might be the cause you can test them if you remove the plugs 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 any components that are covering the spark plugs. After removing the plugs place them on a metal surface that is grounded and start the engine. If they are good you will see a strong blue spark across the gap between the tip of the central electrode.

If you don't see any spark, you've 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. It's important to remember that all systems wear down and break over time, and this is especially true of ignition systems. Regular maintenance can reduce the time it takes to repair and prevent major problems at the worst time.
