VEHICLE IDENTIFICATION NUMBERS
Record your vehicle’s identification numbers and key number.
Remove the spare key and store it in a safe place. Your key can be
duplicated only by mating a Polaris key blank with one of your
existing keys, so if both keys are lost, the ignition switch must be
replaced.
