Because it isn't able to harness the full power of devices like the starter, it's a less powerful component that's less likely fail. However, it's still possible for the switch to get damaged or corrosion-prone.

One sign of a damaged switch is the difficulty in turning the key. This can be due to many factors that include incorrectly inserting a key or deteriorating the mechanism over time. It's also common for people to mix up their car key ignition replacement near me keys with someone else's, which can lead to mechanical damage.

Before calling a locksmith you might want to try a few things. First, you'll need to make sure that the battery is fully charged and that there aren't any other electrical issues within the system.

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

Remove the electrical connector so that it doesn't interfere with the test. Set the voltmeter on the resistance or continuity modes and place one lead on one of the terminals on the ignition switch.
