Car would not crank at all, does not make a sound?

Hello,

It sounds like the ignition switch might be faulty.
The ignition switch is the electrical component that the lock cylinder attaches to.
Over time the connectors on the switch become worn and can lose connection. This can trigger a no start of the engine.
Typically, when this happens, as you turn the key there is no click or any sound from the engine or the starter, since they are not getting any power from the switch.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
