Optimise the security of your motorhome with a steering wheel lock, and more.
Devices such as steering wheel locks are a highly effective addition to systems designed to protect electronics from motorhome theft. Because of their high visibility, they’re also an ideal complement to non-visual items such as tracking systems.
And while, ultimately, any anti-theft deterrent can be broken off and/or deactivated by the most determined of thieves, it’s certainly helpful to have on show something that’s visible as a warning to any criminals.
There’s also the time factor involved in a thief attempting to get rid of a security lock, clamp or similar – and the fact that wrestling with such an item will draw attention.
Indeed in 2018 the retailer Halfords announced that sales of steering wheel locks had doubled over the previous 12 months as motorists protected their vehicles against the latest theft trends.
Think of it this way, too. A casual thief will always turn to the easiest alternative, so if your motorhome is lined up with others (in storage, for instance) you’re giving yourself an extra layer of protection and making your motorhome a less easy target.
Here’s some advice on steering wheel locks and more that can help prevent motorhome theft.
Sold Secure and Secured by Design
Owned by the Master Locksmiths Association, the largest trade body of its kind, Sold Secure is a subsidiary that acts as an independent testing house for security products, including things like steering wheel locks, clamps and more, designed for motorhomes.
You’ll see the Sold Secure logo on a wide range of security products – look out for those with an Automotive Diamond or Gold standard. Sold Secure tests devices using the latest known theft techniques and tools.

Look out also for the police-backed initiative, Secured by Design. Note also that Thatcham – the independent body backed by major vehicle insurance companies – no longer assesses physical devices such as wheel clamps and steering wheel locks.

Caravan Guard’s top tips
- If you’re considering a steering wheel lock for your motorhome, it’s always worth measuring the outer diameter of your steering wheel before buying.
- By their nature, items like wheel clamps and steering wheel locks tend to be heavy and bulky. Make sure you have somewhere suitable to store them when not in use.
- Once bought, fit your steering wheel lock whenever leaving your motorhome unattended.
Insurance benefits for Caravan Guard customers
Good security doesn’t just help protect your pride and joy – it can also benefit your insurance. Fitting an approved motorhome steering wheel lock can qualify you for a discount on your motorhome insurance with Caravan Guard*, helping reward owners who take security seriously.

Four motorhome friendly steering wheel locks worth looking at
Star Player #1
Disklok Diamond and Gold Edition
Marketed as “the UK’s strongest steering wheel lock”, this unit, Disklok is perhaps one of the most recognisable physical security products for cars, vans and motorhomes.
The Disklok Diamond Edition is the brand’s flagship steering wheel lock – and is a top Automotive Diamond-accredited device by Sold Secure.
Engineered to resist modern angle-grinder attacks, it’s made with Diamonite R, an advanced composite metal created to blunt, slow and resist blade cutting, even during prolonged attacks.
It’s finished in an Anthracite colour, and like all Disklok models, the Diamond Edition fully encases the steering wheel and spins on attack, preventing thieves from gaining any leverage needed to attack or cut through the steering wheel itself.
Designed to fit around 90% of vehicles, typically, the Medium model is best suited to motorhomes based on the Fiat Ducato and Peugeot Boxer. Note there’s a built-in adjustment of one inch, which allows you to find the perfect size for your steering wheel.
The Diamond Edition also comes with a protective storage case and a soft, stretch-fit steering wheel cover, which helps prevent marks or scratches on leather steering wheels and can be neatly stored inside the Disklok when not in use.
The classic Disklok Gold is available in bright yellow for maximum visual impact, with a less eye-catching but perhaps more modern silver option in some sizes. Instantly visible and built from hardened steel, it’s designed to be a serious deterrent to thieves.
Key features (Diamond Edition):
All-steel reinforced construction with Diamonite R, anti-drill and anti-pick lock, Sold Secure Automotive Diamond standard, adjustable size, three year warranty
Expect to pay £315 (Disklok Diamond Medium) £190 (Disklok Gold Medium)
Exclusive 10% Disklok discount*
We’ve also teamed up with Disklok to offer Caravan Guard customers an exclusive 10% discount on the Disklok Diamond or Gold Edition and accessories until the end of 2026. It’s a great opportunity to upgrade your motorhome security for less. Simply use voucher code CGDSK10 at the checkout*

Milenco Commercial Steering Wheel Lock
Milenco has applied its motorhome and caravan pedigree to this device, which is an adaptation of its High Security Steering Wheel Lock and is designed specifically for motorhomes. It meets Sold Secure’s Gold standard, is extra-long (some 6cm more than the standard car version), and offers a universal fit, so suitable for all van and motorhome steering wheels.

It secures around the spoke of the steering wheel to prevent it from rotating. It’s supplied with three keys, with spares also available.
Key features Steel construction, high-security lock, attack-resistant for 300 seconds.
Expect to pay £70
Star Player #3
Armaplate Resolute Gold
Introducing a new product for 2024 from Armaplate, who have been in the vehicle security industry for almost 30 years. The Armaplate Resolute Gold, is designed, manufactured and distributed in the UK and has Sold Secure’s Automotive Gold rating as well as the approval of the Police Secured By Design team.

When locked into position, the Armaplate Resolute will disable your motorhome’s steering wheel and brake pedal. The lock has a two-piece telescopic design, with one end hooking around the brake pedal and the other end going through the steering wheel and locking together with a single push of a button.

Made from hardened steel it’s lightweight and can be fitted in seconds. The universal design means it will fit most campervans or motorhomes and the lock’s plate has a foam backing so it will not cause damage to your steering wheel, buttons or switches

Expect to pay: £229 (currently discounted to £199*)

Armaplate Resolute Diamond
In comparison to its sister model above, this Compact Diamond model offers an alternative motorhome steering wheel lock.
The Armaplate Resolute Diamond has Sold Secure’s highest Diamond rating and is built with Ferosafe, which claims to be uncuttable, resisting angle grinders, drills and saws. It disables your vehicle’s steering wheel by wrapping its cushioned, round plates above and below your vehicle’s steering wheel and then locking into place.
Fitted in seconds, it’s lightweight and easy to store.
Key features Built with Ferosafe and manufactured in the UK, anti-cutting technology, drill-proof push locks, Sold Secure Diamond, universal fit for nearly all vehicles
Expect to pay: £399
Star Player #5
Stoplock Pro Elite
This is Stoplock’s flagship steering wheel lock, promising universal fitting (although you should always check). The Elite features a deeper bend to its shape than the standat Stoplock model, as well as larger forks.

The manufacturer says the wrap-around design also helps to protect against airbag theft and breaking of the internal steering wheel lock. The bright yellow finish gives it high visibility, too.

Replacement keys are available thanks to a unique arrangement with leading specialist Locktec Security Group.
Key features Easy to fit, supplied with case, unique key code and lifetime guarantee
Expect to pay £60
