If you plug in the charger does it show to charge? This is test for the primary battery circuit.
Do you have a voltmeter? To check the battery pack voltage? I'm thinking you have broken a cable in the primary circuit, the wires from the charger port , to the battery pack, through the battery pack, back to the charger port. Do you hear the solenoid click when you press on the pedal? Check each cable by pulling on it and see if it may not be making a solid connection at batteries and solenoid.
You mention key switch, I wonder if wires may have been broken at the keyswich?
Yes, that would bypass switch for test.
See the link below, the keyswitch gets power from the charger port. If the reed switch does not close when charger s unplugged, no voltage gets to the key, so no voltage goes to the solenoid to close it.
No, the keyswitch only affects the running of the cart. If the charger is faulting, then you have problem with the primary cable circuit. The wires from charger plug, to the battery pack, each battery and cable , back to the charger wires.
