10 Facts About Fix Car Ignition That Will Instantly Put You In Good Mood
How to Fix Car Ignition Problems

The car won't begin to start until the ignition switch transmits an electrical signal to the starter motor. Normal wear and tear over time may cause the switch to malfunction.

Using special tools, you are able to remove the trim on your steering column and access the ignition cylinder module. Refer to the repair manual to get guidance on how to do this correctly.

1. Check the Switch

One of the most frequently encountered ignition problems is a bad switch. It regulates when relays are activated and deactivated through the use of a bridge. It is less likely to fail due to the fact that it doesn't channel full power of devices such as the starter. However, it's still possible for the switch to get damaged or corrosion-prone.

One sign of a bad switch is a difficulty turning the key. This could be due to various reasons such as not inserting the correct key correctly or deteriorating the mechanism over time. It's not common to see people confuse their keys with keys from someone else's. This can cause mechanical damage.

Before calling a locksmith, you may try a few options. First, you'll want to ensure that the battery is fully charged and that there aren't any other electrical issues in the system. You should also examine the voltage of each component to make sure they're providing enough power. Once you've completed these steps, you can begin troubleshooting.

Fortunately the ignition switch is pretty simple to replace. It is connected to the ignition module, a round piece of equipment that holds everything together. To replace it, you'll require an flathead screwdriver as well as something long enough to press the pin into. It could be anything from a paintbrush handle to a kabob skewer, but you should stay clear of any brittle material that could break inside the hole.

Remove any trim pieces that cover the area around the switch once you're ready to go. After this, loosen and remove any screws that are holding the switch in place and then gently remove it. Depending on the model you may need to disconnect any cables connected to it. You can find out how to do this in the instruction manual for your vehicle.

It is recommended to have the ignition switch replaced by professionals if it doesn't work. It's difficult to replace the ignition switch without disabling the steering column. This could lead to the unintentional airbag being deployed when you don't do it correctly. Therefore, it is recommended to let your locksmith take care of this for you.

2. Verify the Wire

Your car may not start if you cannot turn the ignition key or it won't start. This could be due to a variety of components in the ignition system. Understanding how the ignition system functions can help you spot problems and make the appropriate repairs.

The ignition switch is an electrical switch with multiple poles that is operated by the key. It has four positions, including "off", "accessory", "run" and the "lock". If the switch is in the lock position (which usually has a red indicator), the ignition circuit is live and it's not possible to start the engine.

To determine whether the ignition switch is defective or if the ignition coil is faulty, you'll need to do a quick electrical test with the help of a voltmeter. If the ignition switch is set to run, the voltmeter should show approximately 12.6, If the voltage is lower than that, there is an open circuit somewhere within the system. This could be at the solenoid, the battery or the ignition coil itself.

Disconnect the electrical connector from the ignition switch to ensure no other components can interfere with your test. Set the voltmeter on the resistance or continuity modes and connect one lead onto 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 doesn't register any voltage then it's time to replace the switch.


When you're replacing the switch, be sure to use a new ignition cylinder and a top quality key cut to ensure that your car will start and run properly. Also, when you replace the ignition switch, be cautious not to touch the ignition cylinder pins with your tools or they'll get stuck and the engine won't be able to start. You'll need to take off the steering wheel and the gear selector in certain vehicles to gain access to the ignition cylinder. This can be difficult and isn't recommended until you have a vehicle's owner's manual that says it's safe. Otherwise serious damage to the steering column or shifting mechanism is likely.

3. Check ignition cylinder repair

If you've tried the battery, the wiring, and the ignition switch but still cannot get your car started It could be time to inspect the cylinder. The cylinder is the part which holds the key and is mechanically linked to the steering lock to ensure that a would-be burglar can't drive the car without it.

You may notice that your key will not rotate if the cylinder is worn out. Sometimes, the pins inside the cylinder are stuck as they adapt to the shape of the key, which may cause your car to not start. Alternatively, the cylinder may be loose, but a tap with the tack hammer may help to free it. Be careful not to crush the springs in the cylinder and ensure that the key is correctly installed prior to tapping.

If you are required to jiggle and move your key before it can begin, this is another indication that your cylinder has gone bad. This is a sign of trouble and must be fixed immediately as it will only get worse over time.

To test the cylinder, you'll need to disconnect your battery and take off the cover from your steering wheel until you're able to access the ignition module. You should then be able to remove the old ignition switch and the cylinder made of metal. If you don't own a spare switch, you might be able take your original ignition cylinder as well as switch to locksmiths for reuse so long they're in good shape. After replacing the ignition switch and cylinder, make sure to reconnect the wiring, secure it and reattach all covers and panels that you took off.

4. Check Spark Plugs

The spark plug is the ignition system's final link. The engine cannot run in the event that the spark plug fails. It could be in the form of your car not running at all, or it could start but not run well. In either case, the reason is likely to be one of the factors that block or hinder electricity from jumping across the spark plug gap, which causes your engine's air and fuel mixture to start.

Before you begin working on your spark plugs, be sure that you are working on a safe surface, using protective gloves and tools to avoid being hit with. Spark plugs can be extremely hot and can cause serious injuries if touched by hands without gloves.

When a spark plug is bad, you may be able to see that the top of the central electrode has a slight brown or gray substance on it. The electrode may also have a dark coating. These deposits or a build-up of fouling could prevent high-voltage electrical current from jumping across the gap of your spark plug, igniting an engine.

If you suspect that your spark plugs are to blame, you can test them by taking them from their tube inside the ignition coil. You can do this by disconnecting the coil from the plug wire, and following the appropriate procedure for your car to remove components that cover the spark plugs. After removing the plugs, place them on a surface that is grounded, and start the engine. If they're good, you should be able to see a strong blue spark extending across the gap at the tip of the central electrode.

If you don't detect a spark, you've identified the problem. The next step is to go back through the ignition system chain, testing each part until you find out what's stopping the spark plugs from performing their job. It's important to remember that all systems wear out and break over time and this is particularly the case with ignition systems. That said, routine maintenance can reduce the wear and tear and prevent a major headache at the worst possible moment.
