One sign of a bad switch is the difficulty in turning the key. This could be due to various factors such as incorrectly inserting the key or deteriorating the mechanism over time. It's not common to see people mix their keys up with someone else's. This can cause mechanical damage.
If the switch isn't working, there are some things you can try before calling a locksmith.

The ignition switch is a low-voltage multi-pole electrical switch that can be operated by a key. It includes four positions "off", "accessory", "run" and the "lock". When the switch is in the lock position (which usually has an indicator in red), the ignition circuit is active and it's impossible to start the engine.
You can use a voltmeter to quickly test the ignition switch and ignition coil. If the ignition switch is set to run at a certain voltage, the voltmeter should read about 12.6, If the voltage drops below that, it indicates there's an open circuit somewhere within the system. It could be the battery, solenoid, or the ignition coil.
Disconnect the electrical connector from the ignition switch so that there are no other components that could interfere with the test. Then you should set the voltmeter in the resistance or continuity mode and place one lead on one of the ignition key replacement switch terminals. The other lead should be connected to the positive terminal on the battery. If the voltmeter reads "open" or does not detect any voltage, it is recommended to replace the switch.

These deposits or a build-up of fouling could stop high-voltage electrical current from crossing the gap between your spark plug, igniting an engine.
If you suspect your spark plugs could be the cause, you can test them by having them remove them from the tube that is inside the ignition coil. This can be accomplished by disconnection of the coil and the plug wire. Then, you'll need to follow the correct procedure for your car to remove the components that surround the plugs. After you have removed the plugs you can place them on a grounded metal surface and turn the engine. If they are working you will see an intense blue spark near the edge of the central electrode.
