Car won’t start

So my dad just recently bought this 03 civic for $500. The lady we bought it from says all it needed was a new clutch (clutch pedal is loose as hell) and also the car won’t start because her husband installed a push start for security reasons (it’s running to the battery and starter as shown in pictures) and she doesn't know whats wrong with it, i tried to bypass the immobilizer but couldn’t figure out how after watching serveral videos. When i turn the key , the green key light starts flashing and when i hit the push start, all the dash lights go off and a clicking sounds comes out the engine bay.
