How to Fix Car Ignition Problems

A car ignition lock won't start unless the ignition switch is sending an electrical signal to the starter motor. Normal wear and tear over time may cause the switch malfunction.

With the help of specialized tools, you are able to remove the steering column trim and gain access to the ignition cylinder module. Refer to your repair manual for learn how to do it correctly.

1. Check the Switch

One of the most frequently encountered ignition issues is a defective switch. It regulates the time when relays are activated and deactivated by acting as a bridge. Since it doesn't harness the full power of devices like the starter, it's a less powerful component that's less likely fail. However, it's still possible for the switch to be damaged or damaged or corroded.

One sign of a damaged switch is difficulty turning the key. This could be due to various factors, including not inserting the key correctly or wearing out the mechanism over time. It is also common for people to mistake their car keys with someone else's, which can result in mechanical damage.

If the switch isn't functioning, there are a few things you can try before calling a locksmith. First, you'll need to make sure the battery is fully charged and there are no other electrical issues within the system. Also, you should examine the voltage of every component to see if they're providing enough power. After you've completed these steps, you're ready to begin troubleshooting.

Luckily the ignition switch is easy to replace. It is connected to the ignition module, a round component that holds everything together. To replace it, you'll need a flathead screwdriver and something that is long enough to push the pin into. This could be anything from an artist's brush to a Kabob skewer. However, it is best to avoid anything that is brittle and break inside the hole.

If you're ready for the work, you'll have to take off any trim pieces covering the area around the ignition switch. After this, loosen and remove any screws that hold the switch in place and then gently pull it out. Depending on the model, you may need to disconnect any cables connected 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 replace it by an expert. It can be difficult to replace the ignition switch without removing your steering column. This could result in the unintentional airbag being deployed in the event that you don't do it correctly. Therefore, it is recommended to let the locksmith in your area handle this for you.

2. Check the Wire

If you're unable to turn the ignition key or your car won't start, the problem could be related to any number of parts of your car's ignition system. Understanding how the ignition system functions will help you determine the cause of the problem and make the necessary repairs.

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

You can use a voltmeter to quickly test the ignition switch or ignition coil. The voltmeter should be reading around 12.6 volts when the ignition switch is in the running position. If the voltage is lower than that then there is an open circuit within the system. This could be at the battery, the solenoid or at the ignition coil itself.

Connect the electrical connector to ensure that it doesn't interfere with the test. Set the voltmeter on the continuity or resistance modes and then place one lead on one of the terminals of the ignition switch. The other lead should be connected to the positive terminal on the battery. If the voltmeter reads "open" or does not detect any voltage, it is recommended to replace the switch.

When replacing 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. Also, when replacing the ignition switch, you must be careful not to strike the ignition cylinder pins with your tools, or they'll become stuck and your engine won't start. In some vehicles, you'll need to remove the steering column and gear selector to get access to the ignition cylinder. This isn't easy and isn't recommended until you have an owner’s manual that states it's safe. Otherwise serious damage to the steering column or shifting mechanism is possible.

3. Check the Cylinder

If you have tried the battery, the wiring and the ignition switch, but still cannot start your car key Ignition problems It could be time to examine the cylinder. The cylinder is the part that holds the key. It 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 turn if the cylinder has worn out. The pins inside the cylinder may become stuck as they adapt to your key's shape. This could cause your vehicle to not start. Or, the cylinder might be loose however a tap using the tack hammer may assist in releasing it. Be careful not mixing with the springs and make sure your key is properly placed.

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

To examine the cylinder, you must remove the cover on the steering wheel and disconnect the battery. The old ignition switch should be easy to remove, as well as the cylinder made of steel. If you don't have an extra ignition switch lying around, it's that you could take your original ignition switch and the cylinder to a locksmith and reuse them as long as they're in good condition. After replacing the ignition switch and cylinder ensure that you connect the wiring and secure it before reattaching the panels and covers that you removed.

4. Make sure you check the Spark Plugs

The spark plug is the final link in your ignition chain. The engine cannot run when the spark plug is broken. It could be that your car will not start at all or it will run poorly. In either of these scenarios, it's likely that one or more factors are hindering or blocking electricity from jumping across spark plug gaps, which ignites the fuel mixture and air within your engine.

Make sure you wear protective tools and gloves before working with your spark plugs. Spark plugs can be extremely hot and cause serious injuries if they are touched by hands without gloves.

When a spark plug is bad, you may be able to see that the top of the central electrode is covered with a slight brown or gray substance on it. The electrode could also be covered with a dark coating. These deposits or a build-up of fouling could hinder high-voltage electrical currents from crossing the gap between your spark plug, igniting an engine.

If you suspect that your spark plugs may be to blame, you can test them by removing the plugs from their tube in the ignition coil. This can be done by disconnecting the coil from the plug wire and following the appropriate procedure for your vehicle to remove the 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 crossing the gap at the tip of the central electrode.

If you don't see any spark, you have found the issue. The next step is to go back through the ignition chain, testing each element until you can determine what is hindering the spark plugs from performing their job. Every system will wear out and eventually fail and this is especially true for ignition systems. However, regular maintenance can slow the process down and avoid a big headache at the worst time.
