Hello,

So, when you turn the key does it make any noise?

Just so we cover the basics, have you tried to jump start it? It is possible to have a weak battery and not be able to start the engine.

If you are able to jump start the vehicle and it runs normal, then it is just a bad battery and need to be replaced.

If it just makes clicking noise, it could be the starter. As the noise comes from the solenoid and it is unable to engage the starter motor.
First check the starter cable, make sure it is secured and free of any corrosions. Also verify the battery terminal is clean.

Also check the starter relay, located under the hood fuse box. Check for corrosions or burnt pins. That relay can also be tested.

Thank you.
