Locking wheel nuts are a small but important part of your car’s security setup. They prevent thieves from easily removing your alloy wheels. Each car typically comes with one unique locking wheel nut per wheel and a matching key used to remove them.
If you’ve ever faced a flat tyre and realised the locking wheel nut key is missing, you’re not alone. Here’s everything you need to know about what they are, how they work, and what to do if you’ve lost the key.
What Are Locking Wheel Nuts?
Locking wheel nuts (also known as alloy wheel locks or security wheel nuts) secure your car’s alloy wheels in place. Unlike standard wheel nuts, each locking nut has a unique pattern that requires a matching key to remove.
Most new cars, whether leased or purchased, come fitted with locking wheel nuts. If you lease a car, especially a high-value model, locking wheel nuts are standard for extra protection.
How to Find Your Locking Wheel Nut Key
The locking wheel nut key is usually supplied with your vehicle when it’s new. It’s commonly stored in one of the following places:
-
Inside the glovebox
-
Under the boot floor, near the spare wheel
-
In the side storage compartments of the boot
-
Attached to the jack or tyre repair kit
If you can’t find it, check your car’s manual or contact your dealership — they can often provide the key code to order a replacement.
What to Do if You’ve Lost the Locking Wheel Nut Key
Losing your locking wheel nut key can be frustrating, especially if you need to change a tyre. Here’s what you can do:
-
Check if the code card is still in the car:
Some manufacturers provide a small card with the locking nut code — usually in the handbook wallet. -
Contact your car dealer:
If your car is from a main brand like BMW, Audi, or Ford, the dealer can often match your registration or VIN to the right key. -
Use a locking wheel nut removal tool:
If a replacement isn’t available immediately, a mechanic can remove the nuts using a specialist tool without damaging the wheel. -
Avoid forcing or hammering:
Using makeshift tools or force can damage the wheel or bolt, leading to costly repairs.
Can You Drive Without Locking Wheel Nuts?
Technically, yes — you can drive with standard wheel bolts once the locking nuts are removed. However, it’s not recommended to leave your alloys unsecured, especially on newer or high-spec vehicles. Locking wheel nuts add an important layer of protection against theft.
How Much Does a Replacement Locking Wheel Nut Key Cost?
Replacement costs depend on your vehicle’s make and model. Here’s a rough guide:
-
Main dealer replacement: £30–£80
-
Independent garage: £20–£40
-
Emergency removal service: £50–£100
If you lease a car and lose the key, inform your leasing provider or maintenance contact so they can arrange a replacement before your contract ends.

How to Remove a Locking Wheel Nut Without the Key
If you’re stuck and need to change a tyre urgently:
-
Visit a local tyre centre — many have universal locking nut removers.
-
Avoid DIY hacks found online as they often cause wheel or bolt damage.
-
Keep a note of the new key code once replaced for future use.
For leased vehicles, always contact the lease provider or authorised service partner before removal.
Do All Cars Have Locking Wheel Nuts?
Most cars with alloy wheels come with locking wheel nuts fitted as standard. Entry-level models with steel wheels may not include them. Manufacturers such as BMW, Mercedes-Benz, and Audi almost always provide them for added security.
Locking Wheel Nuts and Car Leasing
Locking wheel nuts are standard on most leased cars, especially premium or electric models. If you lose the key during your lease term:
-
Report it to the leasing company or maintenance partner
-
Do not attempt removal yourself
-
Ensure the nuts are re-secured before returning the vehicle at the end of the lease
Keeping the locking wheel nut key safe helps avoid end-of-lease charges or tyre replacement delays.
