2015 Prius C - Trouble with Ignition Switch

2015 Prius C that uses a key for entry (versus a fob). Intermittently, after inserting the key and turning it to activate the car, everything on the dash lights up except the READY indicator and the SHIFT indicator and car will not start. After several attempts or waiting a few minutes, it then works. It's not a battery issue in either the key or the car. Thoughts?

 

All electric systems work when I turn the key. All the normal lights come up on the dashboard except the ready indicator light next to the speedometer and the gear indicator light . Battery seems fine. I can go weeks without this happening and then unexpectedly without a specific pattern I get stuck because the car won’t engage. Any ideas? Thanks for your help

 

Thanks. Will try
