You can remove the steering column trim using special tools to gain access to the ignition cylinder module. Refer to your repair manual for learn how to do it right.

1. Check the Switch

A bad switch is one of the most frequent ignition problems. It regulates the moment relays are activated, and deactivated through the use of a bridge. Since it doesn't channel the full power of devices like the starter, it's a less powerful component that is less likely to fail. However, it's still possible for the switch to be damaged or damaged or corroded.

A defective switch can be identified by a difficulty turning the key. This can be due to many factors that include incorrectly inserting a key or wearing down the mechanism over time. It's also commonplace for people to mix up their car keys with the keys of someone else, which can lead to mechanical damage.

Before calling a locksmith you may try a few options. You'll first want to ensure that the battery is fully charged and there are no electrical issues in the system. Also, you should test the voltage of each component to determine if they're capable of supplying enough power. Once you've completed these steps, you can begin troubleshooting.

The ignition switch is easy to replace. It's connected to the ignition cylinder, a round module that connects everything. It's necessary to use a flathead and something long enough to press the pin in.

The ignition switch is a low-voltage multi-pole electrical switch that is operated by a 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 circuit is active and it's not possible to start the engine.

You can use a voltmeter to quickly test the ignition switch or coil. If the ignition key replacement switch is set to run, the voltmeter should show about 12.6, If the voltage drops below that level, it's a sign there's an open circuit in the system. It could be the battery, solenoid, or the ignition coil.

Disconnect the electrical connector so that it doesn't interfere with the test. Then you should set the voltmeter in the continuity or resistance mode and put one lead on one of the ignition switch terminals. The other lead should go to the positive terminal of the battery. If the voltage gauge reads "open" or doesn't show any voltage it's time to replace the switch.

Make sure you use a new ignition key and high-quality ignition cylinder when replacing the switch to ensure that your vehicle starts and runs correctly.
