this is a 1st for me but maybe someone else has seen it......the run tow switch is uselly under the seat front of batteries in the location of the F&R switch.....have never seen one mounted on the controller itself as close as i have ever seen one is on an e-z go mounted to the plastic cover where the soleniod and controller are located.......never on the controller itself.....so yes you really want this key.....if you can,t find it i think i would disconnect main power and try to take cover off the controller and see what the guts to this keyswitch look like maybe its a simple replacement for another switch or key..........ok so who out here has seen this setup?????......................
