1. Make sure to check the Switch

A malfunctioning switch is one of the most frequent ignition problems. It functions as bridge between two contacts, controlling the relays' activation and deactivation. It is less likely to fail due to the fact that it doesn't channel full power from devices like the starter. It is still susceptible to being damaged or damaged or corroded.

Before calling a locksmith you can try a few things. First, you'll want to ensure that the battery is fully charged and that there are no other electrical issues within the system. Also, you should test the voltage of each component to see if they're providing enough power. Once you've completed these steps, it's time to begin troubleshooting.

Luckily, the ignition switch is pretty simple to replace. It is connected to the ignition module, a round piece of equipment that connects everything. To replace it, you'll require a flathead screwdriver, and something long enough to push the pin into.

The ignition switch is a low-voltage multi-pole electrical switch that is operated by a key. It has four positions that are off, accessory, run and "lock." When the switch is in the lock position (which typically has the red indicator), the ignition circuit is active and it's impossible to start the engine.

You can use a voltage meter to quickly test the ignition switch and ignition coil. When the ignition switch is running and the voltmeter is reading about 12.6, If the voltage falls below that then there is an open circuit within the system. This could be a battery, solenoid, or the ignition coil.

Disconnect the electrical connector so that it does not interfere with the test. Then you should set the voltmeter in the continuity or resistance mode and place one lead on one of the ignition switch terminals. The other leads should go to the positive terminal of the battery. If the voltage meter reads "open" or does not register any voltage then it's time to replace the switch.

When replacing the ignition switch, be careful not to strike the ignition cylinder pins with your tools or they'll get stuck and your engine will not start. In some vehicles, you'll have to remove the steering column and gear selector to access 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 and shifting mechanism is likely.
