Why isn't my Jeep starting all of a sudden?

Stopped into a shop and now it won't start. See the linked video for the noise.

sounds like the starter isn’t engaging.

You can pull the starter off and clean/ grease the shaft, lowest cost fix. Sometimes the grease dries out and the gear won't engage.
Or the return spring could be stuck.
