INTRODUCTION
Vehicle Identification Numbers
Record your snowmobile's identification numbers and key number in
the spaces provided. 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.
