1. Make sure you check the Switch

One of the most common ignition issues is a defective switch. It controls when relays are activated and deactivated by 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. It is still susceptible to being damaged or corroded.

One sign of a bad switch is a difficulty turning the key. This can be due to many factors such as incorrectly inserting a key or deteriorating the mechanism over time. It is also common for people to mistake their Fix Car Ignition keys with another's, which could lead to mechanical damage.

If the switch isn't working, there are a few things you can try before calling a locksmith. First, you'll want to make sure the battery is charged and that there aren't any other electrical issues in the system. Also, you should verify the voltage of every component to ensure they are supplying enough power. Once you've completed these steps, you're ready to start troubleshooting.

This could be the solenoid, the battery or the ignition coil.

Remove the electrical connector from the ignition switch so that no other components interfere with your test. Set the voltmeter in the resistance or continuity modes and place one lead on one of the terminals of the ignition switch. The other leads should go to the positive terminal on the battery. If the voltmeter is "open" or does not show any voltage, you must replace the switch.
