Lug nuts and wheel locks

Lug nuts hold your wheels on; wheel locks need their key to come off. Pick your car to see lug nuts and locks eBay matches to it.

What to check before you buy

Thread size and seat shape (conical, ball or flat) must match your wheels. Aftermarket wheels can need different nuts than the original ones.
Keep the wheel lock key in the car, where you and a tire shop can find it.
Tighten to the torque in your owner's manual, and check them again after the first drive.
