How to Fix Car Ignition Problems
The car won't begin unless the switch transmits an electrical signal to the starter. Over time, normal wear and tear could cause the switch to fail.
You can remove the steering column trim using special tools to access your ignition cylinder module. Refer to the repair manual to get guidance on how to do this in a safe manner.
1. Check the Switch
A defective switch is one of the most common ignition issues. It functions as bridge between two contacts, regulating when relays activate and deactivate. Because it isn't able to transmit the full power of devices such as the starter, it's a lighter-duty component that's less likely fail. The switch can still be damaged or corrosion-prone.
One indication of a defective switch is difficulty turning the key. This can be due to various reasons that include the wrong way to insert a key, or deteriorating the mechanism over time. It's not uncommon for people to confuse their keys with keys from someone else's. This can cause mechanical damage.
If the switch isn't functioning there are a few things you can try before calling a locksmith. First, ensure that the battery is fully charged and that there are no other electrical issues that could be affecting the system. Also, you should examine the voltage of each component to ensure they are sufficient power. After you've completed the above steps, you're ready to begin troubleshooting.
Luckily, the ignition switch is easy to replace. It is connected to the ignition module, a round piece of metal that holds everything together. It's necessary to use an elongated flathead as well as something that is long enough to push the pin into. It could be anything from a paintbrush handle to a Kabob skewer, but you should stay clear of anything that is brittle and break within the hole.
When you're ready to do the work, you'll need to take away any trim pieces that cover the area around the ignition switch. Once you've done this remove and loosen the screws that hold the switch in place, and then gently pull it out. Depending on the model, you may have to cut off the cables that connect to it. Find out how to do it in the manual of your vehicle.
If the ignition switch isn't working it is recommended to have it replaced by professionals. Replacing it can involve disabling the steering column, which could trigger an unintentional deployment of airbags if done improperly. Therefore, it is recommended to let your local locksmith handle this for you.
2. Verify the Wire
If you're unable to turn the key in the ignition key replacement cost or your car isn't starting, your problem could be related to any of the components in your car's ignition system. Understanding how the ignition system works can help you spot problems and make the necessary repairs.
The lost ignition key switch is an electrical switch that has multiple poles and is operated by a key. It includes four positions "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 not possible to start the engine.
You can use a voltage meter to quickly test the ignition switch or ignition coil. 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 in the system. It could be the solenoid, the battery or the ignition key replacement cost coil.
Remove the electrical connector from the ignition switch to ensure there are no other components that could interfere with your test. Then set the voltmeter to the resistance or continuity mode and put one lead on one of the terminals on the ignition switch. The other lead should go to the positive terminal on the battery. If the voltage gauge reads "open" or does not register any voltage, it's time to replace the switch.
When you're changing the switch, make certain to use a new ignition cylinder and a good quality key cut to ensure that your car will run and start correctly. When you replace the switch, make sure not to strike the pins of the cylinder's ignition with your tools. Otherwise, they'll get stuck and the engine won't run. You'll need to remove the steering wheel as well as the gear selector on some vehicles to access the ignition cylinder. This isn't easy and is not recommended unless you have an owner's manual that states it's safe to do so. If you do not you could cause serious damage to your steering column and the shift mechanism.
3. Check the Cylinder
If you've worked your way through the wiring, battery, and ignition switch but you can't get your car start, it might be time to look at the cylinder. The cylinder is the component that holds the key. It is mechanically connected to the steering lock to ensure that a would-be burglar can't drive the car without it.
You may be noticing that your key does not rotate if the cylinder is worn out. Sometimes, the pins inside the cylinder get stuck as they adapt to the shape of the key, which could cause your car to not start. The cylinder could also be shaky, but a tap with the tack hammer may aid in releasing it. Be careful not to crush the springs inside and ensure that the key is correctly inserted before tapping.
Another indication that your cylinder is failing is if you have to move the key around and try multiple positions before it starts. This is a bad indication and should be corrected immediately, as it can only get worse with time.
To check 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 metal ignition cylinder. If you don't have an extra ignition switch lying around, it's likely that you could 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, ensure that you reconnect the wiring harness, secure it in place and then reattach any covers or panels you removed.
4. Check the Spark Plugs
The spark plug is your ignition system's final link. When it breaks, the engine can't run. It could be that your car won't start at all or it will run badly. In either case, it is likely that one of several things are hindering or preventing the flow of electricity across spark plug gaps, which ignites the mixture of fuel and air inside your engine.
Before you begin working on your spark plugs, make sure that you work on a level surface and using protective gloves and tools to prevent being struck. Spark plugs can be very hot and can cause serious injuries if they are touched with bare hands.
When a spark plug goes bad, you may observe that the edge of the electrode's central portion has a slight brown or gray residue on it. The electrode could also have a dark coating. The deposits or fouling may stop high-voltage electrical current from crossing the gap of your spark plug and igniting an engine.
If you think that your spark plugs may be to blame you can test them by removing the plugs from their tube in the ignition coil. You can do this by disconnecting the coil from the plug wire, and following the proper procedure for your car to remove any components that are covering the spark plugs. Once you have removed the plugs you can place them on a grounded metal surface and crank the engine. If they're good you will see a bright blue spark across the gap between the tip of the central electrode.
If you don't see a spark you have found the issue. The next step is to work back through the ignition chain, testing each component until you discover what's hindering the spark plugs from performing their job. It's important to remember that all systems wear down and break down over time, and this is especially true of ignition systems. Routine maintenance can help to reduce the time it takes to repair and prevent a major headache in the worst case.
