How to Fix Car Ignition Problems

The car won't begin unless the switch sends an electrical signal to the starter. Over time, normal wear and tear could cause the switch to malfunction.

Using specialized tools, you can remove the steering column trim and gain access to the ignition cylinder module. Check out your repair manual to learn how to do it correctly.

1. Check the Switch

A defective switch is one of the most frequent ignition problems. It regulates when relays are activated and deactivated through the use of a bridge. It is more likely to fail since it does not channel full power from devices like the starter. It is still susceptible to being damaged or corrosion-prone.

A malfunctioning switch can be recognized by a slow time turning the key. This could be due to various reasons that include incorrectly inserting a key or the mechanism being worn out over time. It's also common for people to mistake their keys to their car with those of another's, which could lead to mechanical damage.

Before contacting a locksmith, you might want to try a few things. First, you'll need to make sure the battery is charged and that there are no other electrical issues that could be affecting the system. You should also check the voltage of every component to make sure they're sufficient power. After you've completed the above steps, you can 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 need an flathead screwdriver as well as something long enough to press the pin into. This can be anything from a paintbrush handle to a Kabob skewer. However, it is best to avoid anything brittle that could break within the hole.

When you're ready to do the job, you'll need to remove any trim pieces covering the area around the ignition switch.

It's best to leave it to your local locksmith to handle this.

2. Check the Wiring

If you are unable to turn the ignition key or your car isn't starting, your issue could be due to any of the components of your vehicle's ignition system. Understanding how the ignition system works will help you identify problems and make the necessary 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, accessory, run and "lock." If the switch is locked (which is typically indicated by the red light) the ignition circuit is active and it is impossible to start your vehicle.

To determine whether the ignition switch damaged or if the ignition lock repair services coil itself is bad, you must conduct a quick electrical test using a voltmeter. The voltmeter should read around 12.6 volts when the ignition switch is in the running 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 coil.

Remove the electrical connector so that it doesn't interfere with the 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 be connected to the positive terminal of the battery. If the voltmeter shows "open" or fails to register any voltage, you should replace the switch.

When replacing the switch, be certain to use a new ignition cylinder and a top quality key cut to ensure that your car will run and start correctly. When you replace the switch, be sure not to hit the pins of the ignition cylinder with your tools. In the event of a collision, they'll get stuck and the engine will not run. In some vehicles, you'll need remove the steering column and gear selector in order to access the ignition cylinder. This can be a challenge, and it is not recommended until you have an owner’s manual that says it's safe. If you do not then you could cause severe damage to your steering column and shift mechanism.

3. Check the Cylinder

If you've gone through the wiring, battery, and ignition switch but you can't get your car ignition repair start, it might be time to check the cylinder. The cylinder is the part that holds the key and is mechanically connected to the steering lock to ensure that burglars won't be able to drive the car without it.

You may notice that your key will not turn if the cylinder is worn out. Sometimes, the pins in the cylinder become stuck when they adjust to the shape of the key, which can cause your car to not start. The cylinder could also be sloppy. A tap with the small tackhammer may aid. Just be careful not to jumble the springs inside and ensure that your key is correctly inserted before tapping.

If you need to jiggle and move your key before it will begin, this is another indication that your cylinder is become damaged. This is a negative sign and should be corrected right away, since it will only get worse with time.

To examine the cylinder you'll need to unplug your battery and remove 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 ignition switch lying around, it's likely possible that you can take your original ignition switch and cylinder to a locksmith to reuse them as long as they are in good condition. After replacing the ignition switch and cylinder make sure to reconnect the wiring and secure it before reattaching the covers and panels you took off.

4. Check the Spark Plugs

The spark plug is your ignition system's last link. If it fails it stops the engine from running. 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 electricity from jumping across spark plug gaps, which in turn ignites the fuel mixture and air within your engine.

Before you begin working on your spark plugs, be sure that you are working on a level surface and using gloves and tools that are protected to keep from getting struck. Spark plugs can get very hot and can cause serious injuries if they are touched with bare hands.

When a spark plug goes bad, you may notice that the tip of the central electrode has a light gray or brown residue on it. The electrode may also have a dark coating. These deposits or a build-up of fouling could stop high-voltage electrical current from jumping across the gap of your spark plug, igniting an engine.

If you believe that your spark plugs may be to blame, you can test them by removing them from their tube inside the ignition coil. This can be done by disconnecting the coil and the plug wire. After that, you'll have to follow the proper procedure for your vehicle in order to remove the components that surround the plugs. Once you have removed the plugs, you can place them on a metal surface that is grounded and turn the engine. If they're good, you should see a strong blue spark across the gap at the tip of the central electrode.

If you don't see a spark, you've found the problem. The next step is to go backwards through the ignition chain and test each part until the spark plugs aren't functioning. It's important to remember that all systems wear down and break over time and this is particularly true of ignition systems. However, regular maintenance can to slow down the process and avoid a major headache at the worst moment.
