How to Fit Wheel Locks

LNS-1Auto-Grip® Wheel Lock Fitting Instructions

NOTE: Vehicle and Wheel manufacturers may make changes at any time. Check that you have the correct type of wheel lock by comparing thread type, seating, and thread length to the original nut or bolt.



  1. Record the lock code found on the head of the lock key and keep in a safe place, preferably the vehicle’s cubby drawer. You will need this code to get a replacement key.
  2. Remove a single nut or lug from the wheel on which the lock is to be installed and inspect the thread or wheel stud. Be sure stud is tight and all threads are undamaged. Replace with new stud if necessary.
  3. Thread the new chrome lock onto the wheel stud by hand. The lock should screw in easily or the thread is incorrect
  4. Using the vehicle’s wheel wrench (or a torque wrench), and the lock key, tighten the lock to vehicle or wheel manufacturer torque specifications.
  5. Check that the wheel is secure fully seated against the wheel. Ensure that the lock has the correct thread engagement. The minimum engagement is equal to the thread diameter; i.e. 12mm lock requires 12mm of thread engagement.

 Do not use an pneumatic impact wrench. It will damage the high quality chrome finish on these locks.

  1. Repeat steps 1 through 5 for each wheel on the vehicle.
  2. Store the lock key in the vehicle storage compartment.
  3. Attach the spare lock key (if supplied) to your vehicle’s spare keys and store at home/office.
  4. Retighten all locks to proper torque specification after the first 40km of driving.
