Possible causes and actions:
Low or faulty battery
* Check the battery and connect it to the charger or replace it.
Electrical wiring problems
* Check for damage or breaks in the electrical wiring.
* Check battery terminals and ground connections.
Faulty starter
* Try cranking the engine with the key. If it does not turn or turns slowly, the starter may be faulty.
* Check the starter terminals and try tapping it with a hammer to see if it is stuck.
Faulty ignition switch or starter switch
* Try turning the key to all positions. If you do not hear any clicking or buzzing sounds, this may indicate a problem with the ignition switch or starter switch.
Car alarm problems
*Check whether the car alarm is activated, which may prevent the engine from starting.
* Try disabling the alarm or using a spare key to bypass it.
Faulty engine control unit (ECU)
*If none of the above options help, the engine control unit may be faulty.

Additional actions:
* Make sure the key is in the “ON” position.

* If possible, try starting the engine using jumper cables.
*Consult a professional mechanic if the problem does not resolve on your own.
