My 2018 Fit has an electrical problem. The alarm started going off randomly. I disconnected the hood latch, and that fixed the problem. It was replaced a year which solved the problem until this last incident. I was walking by the car, and there was an occasional buzzing sound from the engine compartment. I could also see that the dash was randomly lighting up. By the time I took the first video of the dash and the last one, the car went from blinking off and on to staying on, no matter what I did.

Then is when it gets weird. After starting the car the car would not turn off. Even after removing both the negative and positive terminals of the battery. It was not until I disconnected the switch in the picture that the car stopped running. After trying to start the car, it now won’t restart and keeps displaying a “Keyless Start System Problem.”

Where do I begin to figure out what's happening?

 

Sounds like the car's telling you exactly what the problem is...
