How to Fix Car Ignition Problems

The car ignition lock won't begin unless the switch sends an electrical signal to the starter. Over time wear and tear may cause the switch to malfunction.

Utilizing special tools, you can take off the steering column trim and gain access to the ignition cylinder module. Consult your repair manual to learn how to do it correctly.

1. Check the Switch

One of the most common ignition issues is a defective switch. It controls the moment relays are activated, and deactivated, acting as bridge. It is less likely to fail due to the fact that it does not channel full power of devices like the starter. The switch can still be damaged or corroded.

A defective switch can be identified by a difficulty turning the key. This could be due to various factors such as improperly inserting the key, or wearing out the mechanism over time. It's also common for people to mix up their car keys with another's, which could result in mechanical damage.

Before calling a locksmith ignition replacement cost, you may try a few options. First, you'll need to make sure the battery is charged and that there aren't any other electrical issues in the system. You should also examine the voltage of every component to determine if they're supplying adequate power. Once you've completed these steps, it's now time to start troubleshooting.

The ignition switch is easy to replace. It is connected to the ignition module, which is a round component that holds everything together. To replace it, you'll require an flathead screwdriver as well as something long enough to press the pin inside. You can use anything from a paintbrush, to a Kabob stick, but be careful of anything brittle as it could be broken into the hole.

Remove any trimming pieces that cover the area around the switch when you're ready to go. Once you've done this remove and loosen the screws that are holding the switch in place, and then gently pull it out. Depending on the model, you may be required to disconnect the wires that connect to it. You can learn how to do it in the manual of your vehicle.

If the ignition switch isn't functioning it's recommended to have it replaced by an expert. Replacing it can involve disabling the steering column, which could result in unintentional deployment of airbags if done in a wrong manner. It is best to allow your locksmith to take care of this.

2. Check 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 components in your car's ignition system. Understanding how the ignition system functions will help you determine the cause of the problem 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 that are off run, accessory, and "lock." If the switch is locked (which is typically shown by the red light), the ignition circuit is activated and it is impossible to start your car.

To determine whether the ignition switch is bad or the ignition key replacement coil is bad, you have to conduct an electrical test using a voltage meter. When the ignition switch is running at a certain voltage, the voltmeter should read about 12.6, If the voltage falls below that level, it's a sign there's an open circuit somewhere within the system. This could be the battery, solenoid, or the ignition coil.

Connect the electrical connector to ensure that it does not interfere with the test. Then, set the voltmeter to the continuity or resistance mode and place one lead on one of the ignition switch's terminals. The other lead should be connected to the positive terminal of the battery. If the voltage gauge shows "open" or doesn't show any voltage it's time to replace the switch.

If you're changing the switch, make certain to use a new ignition cylinder as well as a high quality key cut to ensure that your vehicle will run and start correctly. When replacing the ignition switch, you must be cautious not to touch the cylinder's pins on the ignition with your tools or they'll become stuck and your engine will not start. You'll need to take off the steering wheel as well as the gear selector on some vehicles to get access to the ignition cylinder. This can be a challenge and should not be done unless you have an owner's manual that indicates that it is safe to do so. If you don't then you could cause serious damage to your steering column and shift mechanism.

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 might be time to examine the cylinder. It's the component that holds your key and is mechanically connected to the lock on the steering wheel so a would-be thief can't steer the car without a key.

You may be noticing that your key does not turn if the cylinder has worn out. Sometimes, the pins inside the cylinder become stuck when they adjust to the shape of your key, which may cause your car to not start. Alternatively, the cylinder may be shaky and a tap using the small hammer from a tack can help to free it. Be careful not to disturb the springs in the cylinder and ensure that your key is correctly inserted before tapping.

Another indication that your cylinder is going bad is when you have to jiggle the key and try multiple positions before it starts. This is a bad indication and needs to be fixed immediately, as it will only get worse over time.

To examine the cylinder, you must remove the cover for the steering wheel and disconnect the battery. Then, you'll be able pull out the old ignition switch and the cylinder made of metal. If you don't have a spare ignition switch lying around, it's possible that you can take your original ignition switch and the cylinder to a locksmith in order to reuse them as long as they're in good condition. After replacing the switch and cylinder ensure that you reconnect the wiring harness and secure it and reattach any covers or panels you've removed.

4. Check Spark Plugs

The spark plug is the final link in your ignition chain. If it fails it will stop the engine from running. It could be in the form of your car not running at all, or it may start but then run poorly. In either case, the reason is likely to be one of a few things that hinder or prevent electricity from crossing the spark plug gap which causes your engine's air and fuel mixture to start.

Be sure to use protective tools and gloves before working with your spark plugs. Spark plugs are hot and can cause serious injuries when you touch them with bare skin.

When a spark plug is bad, you might observe that the edge of the central electrode is covered with some light brown or gray residue on it. It may also have a black coating on the opposite side of the electrode. These deposits or fouling can prevent high-voltage electrical current from crossing the gap between the spark plug and starting an engine.

If you suspect that your spark plugs could be the culprit you can test them if you remove them from their tube inside the ignition coil. This can be accomplished by disconnecting the coil as well as the plug wire. Then, you will be required to follow the correct procedure for your vehicle to take off the components that are covering the plugs. After you have removed the plugs you can place them on a surface that is grounded and then crank the engine. If they're working, you should be able to see a strong blue spark at the edge of the central electrode.

If you don't see any spark, you've found the problem. The next step is to go back through the ignition chain, testing each component until you discover what's stopping the spark plugs from doing their job. It is important to keep in mind that all systems wear out and break down with time, and this is especially applicable to ignition systems. That said, routine maintenance can slow the process down and avoid a major problem at the worst moment.
