1. Make sure to check the Switch

A bad switch is one of the most frequent ignition problems. It controls the moment relays are activated, and deactivated through the use of a bridge. Because it isn't able to transmit the full power of devices such as the starter, it's a lighter component that's less likely to fail. The switch can still be damaged or corroded.

One sign of a bad switch is difficulty turning the key. This can be caused by many factors that include not inserting the correct key correctly or the mechanism being worn out over time. It's also common for people to mistake their car keys with the keys of someone else, which can cause mechanical damage.

Before contacting a locksmith, you may try a few options. You'll first want to ensure that the battery is fully charged and there aren't any electrical issues in the system. You should also check the voltage of every component to make sure they're sufficient power. After you've completed these steps, you'll be able to begin troubleshooting.

Luckily the ignition switch is pretty simple to replace. It is connected to the ignition module, which is a round component that connects everything. To replace it, you'll need a flathead screwdriver, and something that is long enough to push the pin inside.

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

You can use a voltage meter to quickly test the ignition switch and ignition coil. The voltmeter should be reading around 12.6 volts when the ignition switch is in the running position. If the voltage drops below that, it indicates there's an open circuit in the system. This could be the solenoid, battery, or the ignition coil.

Connect the electrical connector to ensure that it doesn't interfere with the test. Set the voltmeter on the resistance or continuity modes and then place one lead on one of the terminals of the ignition switch. The other leads should go to the positive terminal of the battery. If the voltmeter is "open" or fails to register any voltage, you must replace the switch.

Use a brand new ignition key and high-quality ignition cylinder when you replace the switch to ensure your vehicle runs and starts properly. When you replace the switch, ensure not to strike the pins of the ignition cylinder using your tools. In the event of a collision, they'll get stuck and your engine will not run.

It's the component that holds your key and is mechanically connected to the lock on the steering wheel so that a potential thief cannot drive the car without a key.

If your cylinder has started to wear out, you may be noticing that your key isn't able to turn. Sometimes, the pins within the cylinder are stuck when they adjust to the shape of the key, which can cause your car not to start. The cylinder may also be sloppy. A tap using the tackhammer can help. Be careful not mixing up the springs and ensure that the key is correctly inserted.

You might notice a light gray or brown residue on the edge of the electrode if the spark plug is damaged. The electrode could also be covered with an opaque coating. These deposits or a build-up of fouling could hinder high-voltage electrical currents from crossing the gap between your spark plug and igniting an engine.

Then, you'll need to follow the correct procedure for your car to remove the components that surround the plugs. After you have removed the plugs you can place them on a surface that is grounded and crank the engine.
