If you have serious vehicle problems, look for professionals at the dealer’s shop; if you want to fix some small ones by yourself, we have listed a few solutions for you.
Check out if the dashboard lights up when the key switch starts.

See if the battery connection ends and the ground ends connected to the beam are loose; tighten them if the dashboard doesn’t light up or does flicker.

Check the vehicle starter-relay if the starter doesn’t work, and check again after replacing the starter-relay with the cabin lift relay.

If all the above steps cannot start the vehicle, go to the dealer’s shop immediately.
