Because it isn't able to channel the full power of devices like the starter, it's a lighter-duty component that's less likely to fail. It is still susceptible to being damaged or corrosion-prone.

One sign of a damaged switch is difficulty turning the key. This could be due to many factors, including the wrong way to insert a key ignition replacement, or wearing down the mechanism over time. It is also common for people to mistake their car keys with another's, which could result in mechanical damage.

Before calling a locksmith, you might want to try a few things. You'll first want to ensure that the battery is fully charged and there are no electrical issues with the system.

You can use a voltmeter quickly test the ignition switch or coil. If the ignition cylinder replacement near me switch is set to run, the voltmeter should show approximately 12.6, If the voltage falls below that, it means there's an open circuit within the system. It could be the battery, solenoid or the ignition coil.

Remove the electrical connector from the ignition switch to ensure that there are no other components that could interfere with the test. Set the voltmeter in the continuity or resistance modes and 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 reads "open" or does not show any voltage, you must replace the switch.

Use a new ignition key and high-quality ignition cylinder when you replace the switch to ensure your vehicle starts and runs correctly.
