Since it doesn't transmit the full power of devices such as the starter, it's a lighter-duty component that is less likely to fail. However it's still possible for the switch to be damaged or corroded.

A defective switch can be identified by a difficulty turning the key. This could be due to many things such as incorrectly inserting the key or wearing out the mechanism over time. It's not uncommon for people to confuse their keys with keys from someone else's. This can cause mechanical damage.

Before calling a auto locksmith ignition replacement you might want to try a few things. You'll first want to ensure that the battery is fully charged and that there are no electrical issues in the system. It is also important to check the voltage of each component to determine if it's supplying adequate power. Once you've done these steps, it's now time to begin troubleshooting.

Fortunately the ignition switch is simple to replace. It's connected to the ignition cylinder, which is a round module that holds everything together. It's necessary to use a flathead and something long enough to press the pin in.

To determine whether the ignition switch defective or if the ignition coil is bad, you have to conduct an electrical test using a voltmeter. The voltmeter should read around 12.6 volts when the ignition switch is in the running position. If the voltage falls below that, it means there's an open circuit somewhere within the system. This could be a solenoid, battery or the ignition coil.

Connect the electrical connector to the ignition switch to ensure no other components can interfere with your test. Set the voltmeter on the continuity or resistance modes and place one lead onto one of the terminals on the ignition switch. The other lead should go to the positive terminal of the battery. If the voltage meter reads "open" or doesn't register any voltage it's time to replace the switch.
