However, it's still possible for the switch to get damaged or corrosion-prone.

One sign of a damaged switch is a difficulty turning the key. This can be caused by various reasons that include not inserting the correct key correctly or wearing down the mechanism over time. It's not common to see people mix their keys up with keys from someone else's. This could 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 there aren't any electrical issues with the system.

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

Remove the electrical connector from the ignition switch to ensure no other components interfere with the test. Then you should set the voltmeter in the resistance or continuity mode and put one lead on one of the ignition switch terminals. The other leads should go to the positive terminal on the battery.
