Razor needs to think up key starts and not switches that anyone can flip and ride off on.
On my wife's EcoSmart scooter, I replaced the throttle with an ebay unit that had a voltage meter along with a keyswitch. It was fairly easy.
The stock Ecosmart throttle has six wires. Three are for the throttle hall sensor, two (+ and -) for battery voltage when the scooter is on, and the last is an enable wire. The stock throttle has a microswitch that connects battery + to the enable wire when you twist the throttle. Without the enable wire connected to battery postive, the scooter will not go.
On the keyswitch throttle, I connected the three hall wires straightup, and wired the keyswitch to the onboard voltmeter and enable wire at the same time. The onboard voltmeter will then only light up when the key is on.
So now, the scooter's main power switch on the bottom still works to shut off the scooter entirely, but the key switch needs to be activate for the scooter to work.
Also, it would be best if you didn't use blue lighting on your scooter, as that will just draw unnecessary attention to yourself since blue lights are normally used on emergency vehicles.
