Frequently Asked Questions
Are Replacement Keys Available if I Lose the Original Key?
Yes. The manufacturer can replace a lost key; the owner must provide proof of ownership and the lock’s key code. This empowers users to reclaim control while safeguarding wheel security through verified, authorized replacement procedures.
Do These Locks Affect Tire Pressure Monitoring Systems (TPMS)?
No—these locks do not interfere with tire pressure monitoring systems. The wheel locks simply replace lug nuts and sit under hub caps; they free owners to secure wheels without compromising TPMS sensors or their ability to report pressure accurately.
Can They Be Used on Motorcycles or Trailers?
They can be used on some trailers and motorcycles if thread size and seating match; skeptics worry fitment, but confirmation frees owners to protect wheels—measure M14 x 1.5 and cone seat compatibility before installing.
Is There a Warranty or Guarantee for Manufacturing Defects?
Yes — McGard provides a limited warranty against manufacturing defects on the 24019 locks. The company stands behind U.S.-made quality, empowering owners to demand replacement or remedy within warranty terms to reclaim product integrity and freedom.
Are Lubricant or Maintenance Steps Recommended for Long-Term Use?
Yes: a light coating of anti-seize or corrosion-resistant lubricant on threads and key is advised; one in ten users reports smoother removal and prolonged life. Freedom-minded owners should apply sparingly, inspect periodically, and avoid over-torquing.
Conclusion
To summarize, the McGard 24019 wheel locks deliver solid build quality, with through-hardened steel construction and an M14 x 1.5 thread size, machined to OEM tolerances.
