• Never use an impact wrench for installing or removing wheel locks, as this can damage the lock or key.
• Always use a torque wrench to tighten wheel locks to the manufacturer's specified torque settings.
• Keep the wheel lock key in a secure, accessible location within your vehicle, but not in plain sight.
• Do not overtighten the wheel locks.

The McGard 24019 Wheel Lock set typically includes:

• 4 x McGard Cone Seat Wheel Locks (M14 x 1.5 Thread Size)

5. Operation (Removal)

When removing your wheels, remember the key principle for McGard wheel locks: the lock should always be the last thing applied to the wheel and the first thing removed.

1. Prepare for removal: Ensure the vehicle is safely supported (e.g., with a jack and jack stands) and the parking brake is engaged.
2. Remove the wheel lock first: Place the McGard wheel lock key onto the wheel lock. Using a lug wrench, loosen and remove the wheel lock.
3. Remove remaining lug nuts: Proceed to remove the standard lug nuts.
4. Re-installation: When re-installing the wheel, always install the standard lug nuts first, tighten them to specification, and then install the McGard wheel lock as the final step, torquing it to the correct specification.

6. Maintenance

• Regular Inspection: Periodically inspect your wheel locks for any signs of damage, corrosion, or wear.
• Cleaning: Clean the wheel locks with mild soap and water. Avoid harsh chemicals or abrasive cleaners that could damage the finish.
• Key Care: Keep your wheel lock key clean and free of debris. Store it in a safe, dry place.
• Torque Check: After the first 50-100 miles following installation, re-check the torque of all lug nuts and wheel locks to ensure they remain properly tightened.

7. Troubleshooting

7.1 Difficulty Removing/Installing Wheel Lock

• Ensure the key is fully seated onto the wheel lock before attempting to turn.
• Verify you are using the correct McGard key for your specific wheel locks.
• Avoid using excessive force or impact tools, which can damage the key or lock.

7.2 Lost Wheel Lock Key

You will typically need to provide the key code (found on the original packaging or a registration card) to obtain a replacement key.
