What Is a Wheel Lock Key?

When shopping for a new set of aftermarket wheels, you may have heard about wheel locks or wheel lock keys as a safety measure. Wheel locks are lug nuts that lock into the wheel and are difficult to remove without a key. How do wheel locks work? What is a wheel lock key? And what does a wheel lock key look like?

In this article, we explain what a wheel lock is and whether you should have one installed on your vehicle. 

What is a Wheel Lock?

When you have wheels mounted on your vehicle, lug nuts (or bolts, depending on the vehicle) secure the wheel onto the hub assembly. Wheels have different bolt patterns, which refers to the number of lug holes and their arrangement, depending on the make, model, and size of your vehicle. When looking at your car, the bolts are near the center of the wheel surrounding the center bore. 

A wheel lock is a lug nut that’s designed to lock into your wheel and be difficult to remove without a wheel lock key. Regular lug nuts are hex-shaped bolts that fit a torque wrench to remove or secure in place. However, a wheel lock looks different: They have a unique groove pattern on the tip that serves as the “locking” mechanism. Only a wheel lock key with a matching groove pattern can unlock the wheel lock from the wheel.

Why Would You Want a Wheel Lock?

The #1 reason to have a wheel lock is if you’re worried about having your wheels and tires stolen. With regular lug nuts, it wouldn’t be difficult for a thief to loosen your lug nuts and steal your entire wheel, tire and all. If you have a wheel lock in place of a lug nut (most people use only one locking lug nut), it reduces the likelihood of a theft. While it’s not impossible for a thief to remove a wheel with wheel locks, it is much more difficult, which discourages theft. 

Wheel locks are most commonly used by drivers who have to park on the street or in other public areas for long periods of time. Some drivers use wheel locks to protect luxury aftermarket wheels. If, for example, you live in a city that has street parking, you may run the risk of your wheels being stolen overnight. A wheel lock makes it less likely for a thief to take the wheel, as they would need to have the specific wheel lock key needed to loosen the bolts on your wheels. This is because wheel lock keys are not universal: A specific wheel lock key is needed to loosen the corresponding wheel lock. 

Should I Get a Wheel Lock?

Now that you understand what a wheel lock is and how easy it is to remove a wheel without locks, you’re probably wondering if wheel locks are necessary. This depends on your situation and parking habits. Here’s our breakdown of the pros and cons of getting a wheel lock:

Pros of wheel locks

• They're difficult for thieves to remove; deters theft.
• You can park in cities and on the street without having to worry about theft.
• Locks help to protect expensive aftermarket wheels and tires.

Cons of wheel locks

• You must have your wheel lock key on-hand when driving (in case of a flat!).
• If lost or damaged, you’ll need a replacement that exactly matches your wheel locks.
• Mechanics and auto shops will need your wheel lock key for tire rotation, flat repairs or brake service. 

The bottom line is that wheel locks aren’t necessary, but they offer peace of mind if you have nicer wheels/tires and park in an area where vehicles are vulnerable to crime. Wheel locks also aren’t a 100% assurance of not having your wheels stolen. It’s still possible for a determined thief to grind down the wheel lock so they can loosen it and steal your wheel. However, wheel locks are a deterrent. 

Where can you find wheel locks?

Any place that carries auto parts, tires and wheel accessories will likely carry wheel locks. If you lose or damage the wheel lock key, first check for the spare. Many wheel locks come with two keys.

Many wheel lock key manufacturers include registration cards or codes. If you registered your key and saved the code, you may be able to order a replacement. Professional tire shops may have universal keys, or they'll have the tools to remove the locks without damaging your wheels. 

How Do You Use A Wheel Lock?

Wheel locks tighten just like normal lug nuts, with the main difference being that you’ll need to use a wheel lock key to tighten the wheel lock. The wheel-lock key works like a special “socket” that attaches to a wrench. Because of this, you can’t use a standard tire iron or a standard torque wrench; you'll need a torque wrench with removable socket heads. But once you set the wheel lock key into the wrench, you can loosen and tighten your wheel locks as you would with standard lug nuts.

If you go to a mechanic, you’ll need to make them aware that you have wheel locks on your wheels and give them the wheel lock key beforehand to use. They usually use electric tools to remove lug nuts and will need your wheel lock key to get the wheel locks off. 

What About A Steering Wheel Lock?

This is a separate security measure that involves locking your steering wheel in place so that someone who breaks into your vehicle can’t rotate your steering wheel without the steering wheel lock key.
