How to Fix Car Ignition Problems

The car ignition switch repair won't begin unless the switch transmits an electrical signal to the starter. Normal wear and tear over time may result in the switch not functioning properly.

With the help of specially designed tools, you can take off the steering column trim and access the ignition cylinder module. Refer to your repair manual for learn how to do it correctly.

1. Make sure you check the Switch

A bad switch is among the most frequently encountered ignition issues. It regulates when relays are activated and deactivated through the use of a bridge. Because it doesn't harness the full power of devices such as the starter, it's a less powerful component that is less likely to fail. It is still susceptible to being damaged or corrosion-prone.

One sign of a bad switch is difficulty turning the key. This can be due to various reasons such as the wrong way to insert a key, or wearing down the mechanism over time. It's not uncommon for people to mix their keys up with someone else's. This could cause mechanical damage.

Before calling a locksmith you might want to try a few things. You'll first want to ensure that the battery is fully charged and there are no electrical issues within the system. It is also important to examine the voltage of every component to determine if they're supplying adequate power. After you've completed the above steps, you're ready to begin troubleshooting.

Luckily the ignition switch is simple to replace. It's connected to the ignition cylinder, which is a round module that connects everything. To replace it, you'll require a flathead screwdriver, and something that is long enough to push the pin inside. You can make use of anything from a paintbrush, to a kabob stick, but avoid anything that is hard as it could cause damage to the hole.

If you're ready for the work, you'll have to remove any trim pieces that cover the area around the ignition switch. After you've removed the trim pieces take off any screws that hold the switch in place. Then, carefully pull it out. Depending on the model, you may also need to disconnect the wires that connect to it. Find out how to do this in the instruction manual for your vehicle.

If the ignition switch isn't working it is recommended to have it replaced by professionals. It's difficult to replace the ignition switch without disabling the steering column. This could lead to an accidental airbag being deployed in the event that you don't do it correctly. It's best to allow your locksmith to take care of this.

2. Check the Wire

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

The ignition switch is a low-voltage multi-pole electrical switch that can be turned by the key. It includes four positions "off", "accessory", "run" and the "lock". When the switch is in the lock position (which typically has a red indicator), the ignition circuit is active and it is not possible to start the engine.

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

Connect the electrical connector to the ignition switch to ensure 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 voltage meter reads "open" or doesn't register any voltage then it's time to replace the switch.

Use a brand new ignition key and a top-quality ignition cylinder when you replace the switch to ensure that your vehicle runs and starts properly. When replacing the switch, be sure not to strike the pins of the ignition cylinder using your tools. Otherwise, they will get stuck and the engine won't be able to run. In certain vehicles, you'll need to remove the steering column and the gear selector to access the ignition cylinder. This isn't easy and should not be done unless you have an owner's manual that indicates it's safe to do so. Otherwise severe damage to the steering column and shifting mechanism is likely.

3. Check the Cylinder

If you've worked your way through the wiring, battery and ignition switch, but cannot get your car to start, it could be time to check the cylinder. The cylinder is the component which holds the key and is mechanically attached to the steering lock to ensure that burglars won't be able to drive the car if it's not there.

If your cylinder is beginning to wear out, you may be noticing that your key isn't able to turn. The pins in the cylinder can get stuck as they adapt to your key's shape. This could cause your vehicle to not start. The cylinder may also be sloppy. Tapping it with the small tackhammer may help. Just be careful not to crush the springs inside and ensure that your key is properly placed before tapping.

If you have to jiggle and move the key before it will start, this is another sign that your cylinder has gone bad. This is a sign of trouble and needs to be fixed immediately, as it will only get worse with time.

To check the cylinder you must remove the steering wheel cover and disconnect the battery. The old ignition switch should be simple to remove, as well as the cylinder for ignition made of metal. If you don't have an extra ignition switch lying around, it's likely possible that you can take your original ignition key replacement switch and the cylinder to a locksmith and reuse them as long as they're in good condition. After replacing the switch and cylinder make sure you connect the wiring harness and secure it and then reattach any covers or panels you removed.

4. Check the Spark Plugs

The spark plug is the ignition system's final link. The engine cannot run in the event that the spark plug fails. This can take the form of your car not running at all, or may start but run poorly. In any case, the root is likely to be one of a few factors that block or hinder electricity from crossing the spark plug gap, which allows your engine's gas and fuel mixture to start.

Before you begin working on your spark plugs, be sure you're working on a safe surface and using gloves and tools that are protected to avoid being hit with. Spark plugs can be extremely hot and could cause serious injuries if they are handled with hands that are not protected.

If a spark plug goes bad, you might be able to see that the top of the electrode's central portion has a light gray or brown substance on it. The electrode may also have an opaque coating. These deposits or fouling can stop high-voltage electrical current from crossing the gap of the spark plug and starting an engine.

If you suspect that your spark plugs may be to blame, you can test them by taking them from their tube inside the ignition coil. This can be done by disconnecting the coil as well as the plug wire. Then, you'll be required to follow the correct procedure for your vehicle to remove the components that surround the plugs. After you have removed the plugs, place them on a surface that is grounded and begin the engine. If they're good, you should see a strong blue spark crossing the gap between the tip of the central electrode.

If you don't see a spark, you've identified the issue. Next, you'll need to go backwards through the ignition cylinder lock repair chain and test each part until the spark plugs aren't functioning. All systems will wear out and eventually fail, and this is particularly true for ignition systems. But, regular maintenance can help slow the process down and avoid a major headache at the worst possible time.
