Disklok UK and the full-cover steering wheel lock

Disklok UK is the company behind the Disklok, a full-cover steering wheel lock presented on its site as the UK's strongest. The device is a highly visible, all-steel physical deterrent whose design has been developed in house in the UK since the early 1990s. The company states that the design has been continuously adapted to keep pace with criminal attack methods and tools.

The product's distinguishing feature is a spinning mechanism that activates when the lock is attacked, which the company says prevents the vehicle's own steering wheel lock from being broken and stops the car being steered away. Because it covers the whole wheel, the manufacturer presents it as a defence against cutting, the most common way of removing a steering wheel lock, and also against theft of airbag assemblies and against key cloning and keyless relay entry thefts.

Origins and three decades on the market

The company traces the product to 1993, when its founder invented the Disklok after two Escort RS Mark II Turbo vehicles were stolen within the same year. From its launch until 2005, the site states, the Disklok won every award for the most robust vehicle security device, to the point that testers conceded its strength. The company describes itself as the UK's premier full-cover steering wheel lock for three decades.

Despite the advanced security features fitted to modern cars, the company reports continued strong sales, particularly in what it identifies as susceptible markets: light premium hatchbacks, saloons and SUVs, light commercial vehicles, motorhomes, Land Rovers and classic cars.

Certification and police specification

The Disklok carries the Sold Secure Automotive Gold certification, awarded by what the company describes as the premier testing and certification house for security products. The lock is designed to surpass every aspect of that Gold testing, with annual reviews. It also holds Secured by Design (SBD) status and a police preferred specification, and the company says it works with police forces to understand current attack methods and that the product is trusted by all UK police forces.

According to the company, the device often qualifies for insurance discounts. Its partner pages name Caravan Guard and Greenlight Insurance.

Editions and angle grinder resistance

The range includes the Gold Edition, which the company presents as an enhancement in security with increased resistance to angle grinder attacks, using embedded specialised materials. A Diamond Edition is also listed in the catalogue. The company frames this as part of a process of constant development, using material technology to keep the defences evolving.

Sizing across vehicle types

The Disklok range covers a wide variety of steering wheel sizes and is aimed at cars, 4x4s, vans and motorhomes. The company recommends measuring the diameter of the steering wheel before buying and provides a measuring guide and a size-selection section on the site. A stock notice on the site indicated that Gold Edition Diskloks were out of stock, with expected availability in mid-to-late November 2026; new Gold Edition Small models would initially be available in Silver, with an updated Small size suitable for steering wheels measuring 35–39.5 cm, and Yellow and Medium versions to follow later. The notice stated that all arrival dates are estimates and may change.

Support, spares and accessories

Beyond the locks themselves, the site sells accessories and provides support material covering how to use the Disklok, troubleshooting and frequently asked questions. Replacement keys can be ordered through a dedicated section, and customers can register an account to manage orders.
