What you do
Locksmiths fit new locks, repair and replace faulty or worn mechanisms, open locked doors and vehicles for customers who are locked out, re-key locks to new combinations, cut replacement keys, and carry out security surveys advising clients on upgrading their physical security. The work divides between emergency call-out (responding to lockouts, break-ins, and security failures), planned installation work (fitting new locks, deadbolts, and multi-point locking systems for domestic and commercial customers), and automotive locksmithing (opening, programming, and replacing key fobs and transponder keys for modern vehicles).
Locksmiths may also install and service safes, access control systems, and electronic security measures alongside traditional mechanical lockwork. Security surveys — assessing a property and recommending improvements to meet insurance requirements — are a growing part of the role. Some specialise in heritage and antique lock work, repairing or reproducing period locks and keys for listed buildings.
The Master Locksmiths Association (MLA) is the recognised professional body in the UK. MLA membership requires passing a technical examination and a business inspection — it provides consumer credibility and access to trade procurement networks. The MLA's approved training courses are the most widely recognised entry route, though there is no statutory regulation of the trade.
Why this career is resilient
Locksmithing is inherently local and immediate: when someone is locked out, they need a local locksmith within the hour. Emergency call-out work is insensitive to economic cycles — security needs are constant, and lock failures are not deferred in a recession. The domestic and commercial property stock requires continuous lock maintenance, replacement after break-ins, and upgrades to meet insurance requirements, providing a steady non-emergency income base. Automotive locksmithing has grown significantly as vehicle security becomes more sophisticated, requiring specialised equipment and training that restricts competition.
MLA approval signals trustworthiness to consumers and insurers and creates a competitive advantage in a market where customers must choose between unknown tradespeople. Self-employment is the norm — most locksmiths operate alone or in small firms, building a local client and referral base over time.
A typical day
The day starts with two planned jobs: fitting a new five-lever mortise lock and a night latch on a domestic front door following a break-in, and re-keying a small commercial unit after a staff change. Mid-morning emergency call: a customer locked out of their house — attend, confirm identity and authority, pick the lock, fit a new cylinder. Afternoon: a security survey for a small business — assess their locks, door frames, and padlocks, and write up a recommendation letter for their insurance review. On-call evening: one more lockout call after hours.
