Why does my Kia Picanto not start?

I have a Kia Picanto and it won't start, even after putting in a new battery. What could be the possible causes?

It could be a faulty starter motor. Have a mechanic check it for any issues and replace if necessary.

Another possibility is a problem with the ignition switch. Have it inspected and repaired if needed.

It could also be an issue with the fuel system, such as a clogged fuel filter. Consider getting it checked and replaced if needed.
