ATV Replacement Keys

For some vehicles, Polaris offers key blanks that can be cut using an existing key. If both keys have been lost, you will need to replace the ignition. Contact your Polaris Dealer for key and ignition replacement assistance. Reference the information below when contacting them. 

For all model year 2021 and newer ATVs, 2019-2020 Sportsman 570/570 Utility, 2016-2020 Sportsman 850/850 High Lifter Edition and 2019-2020 Sportsman XP 1000, use the following key blank and key cover. Note that keys with non-removable covers cannot be copied onto key blanks. See your Polaris Dealer for more information. 

  • The key blank is part number 4080125. 
  • The cover for this key is part number 5458344. 

The ATVs not listed above use the key shown below. To determine how to replace your key, first identify which key type you have.

To identify which series the key is, locate the four digits on the original key as shown below. For 4000 series blanks, reference all four digits stamped on the original key.

Youth Keys
For Outlaw 50, Outlaw 90, Outlaw 110, Sportsman 90, Sportsman 110, and Phoenix 200, the required key can be determined by the direction of the key groove.

Groove is determined when holding the key, ready to put into the ignition.

  • If your key has a groove on the right-hand side, use key blank 0453143.
  • If your key has a groove on the left-hand side, use key blank 0453372. 

Additionally, you can tell which key blank you need by checking the number on the key tag attached to the original key ring. If the first digit in that number is odd, you need key blank 0453143. If first digit of the number is even, you need key blank 0453372.

If both keys have been lost, you will need to replace the ignition. See an authorized Polaris Dealer for assistance.
