Founded in 1986 by David Crossman as a home-based entry system business, DES Locksmiths has grown into an industry leader operating from a state-of-the-art 5,500 sq. ft. facility on Canvey Island, Essex. Today, the company is proudly run by David’s sons, Lee and Nicky Crossman, whose combined expertise drives our vision to shape the future of controlled access for housing associations, local councils, and developers nationwide.

Over nearly four decades, we have evolved from installing intercoms to managing high-security master key suites controlling over 50,000 locks for long-standing partners like Peabody, Guinness Trust, and Southend City Council. As one of the UK’s largest Mul-T-Lock stockists, we specialise in comprehensive access control, secure entry systems, restricted key cutting, and wayfinder signage.

Driven by innovation and post-Grenfell fire safety requirements, we developed Golden Key Secure—a groundbreaking, high-security master key solution designed to give emergency services secure communal access while preventing unauthorised entry. Now expanding nationwide, the Golden Key is carried by fire appliances across London, Essex, Surrey, and beyond, establishing an essential "golden thread" of safety and emergency protocols.

What sets us apart is our dedication to long-term security solutions over quick fixes. By combining Lee’s operational and administrative background with Nicky’s technical expertise in access control, we deliver durable products, first-time fixes, and forward-thinking security management tailored to modern high-rise and multi-residential buildings.
