From One Van to a Nationwide Network
Keys4U was founded in 2008 by James Harrington, a master locksmith with a simple mission: to provide fast, honest and affordable locksmith services to homeowners and businesses across the UK.
Starting with a single van in London, we quickly built a reputation for reliability and quality workmanship. Word spread, and within a few years we had expanded to cover the entire South East — and then the whole of the UK.
Today, Keys4U is one of the UK's most trusted locksmith networks, with hundreds of vetted engineers stationed across England, Scotland, Wales and Northern Ireland. We've completed over 50,000 jobs and earned more than 3,800 verified five-star reviews.
Our values haven't changed: transparent pricing, no hidden fees, and a genuine commitment to your security and peace of mind.
