What it is

A call-out service that opens locked doors, replaces and upgrades locks, and fits security hardware such as door chains, window locks and letterbox guards at customers' properties.

Your first three steps

  1. Book a locksmith training course and practise on a range of common locks
  2. Buy a starter toolkit and a stock of popular cylinders and hardware, then get insurance
  3. Set up a Google Business Profile and tell local letting agents you cover call-outs
Who pays

Homeowners locked out or worried about security, landlords, letting agents and small businesses.

How it makes money

A call-out fee plus labour and parts for each job, with higher prices for urgent or out-of-hours work and repeat work from landlords and agents.

Skills that help
  • Practical, fine hand skills
  • Calm and reassuring with stressed customers
  • Honest pricing and good record keeping
Watch out for
  • Public liability insurance, and check whether cover includes lock-opening and your tools
  • The locksmith trade is not generally licensed in the UK, but check for any changes and whether a trade body membership or DBS check would help win work
  • Proof of identity and ownership before opening a door, to avoid helping someone break into a property
  • Unreliable lead-generation sites can charge high fees, so work out your costs before signing up
  • Out-of-hours work can disrupt your evenings and weekends
