Said It Here

Why won't my electric lawnmower start when I push the button?

An electric lawnmower may fail to start due to a safety key that is slightly unseated or a defective ignition coil. Ensuring the plastic safety key is fully plugged in restores the circuit and gets the mower running.

“Check that the safety key is fully seated, those little plastic doodads can look plugged in but be a millimeter off and kill the whole circuit.”source ↗
