Many UK homeowners do not use professional locksmiths even after moving into a new property. According to research by Keytek Locksmiths, 74 % of new homeowners in Great Britain did not change their locks after moving in, which can leave them more vulnerable to break-ins and may affect insurance cover.
Professional locksmiths provide 24/7 emergency response, accurate diagnostics, and skilled installations that reduce long-term security risks compared with DIY attempts, which can damage locks and weaken protection.
Industry experts note that contacting a qualified local locksmith quickly during a lockout or upgrade can save time, prevent costly mistakes, and improve overall home security because trained professionals spot weak entry points residents often miss.
