A locksmith handles lockouts, lock changes, snapped keys and security upgrades. Locksmithing is not a licensed trade in the UK — anyone may advertise as one with no qualification or vetting — so Master Locksmiths Association membership, which requires exams, inspection and a criminal-record check, is doing the work a licence does elsewhere. It matters most on an emergency callout.

| Job | Locksmith | Handyman | Door supplier |
|---|---|---|---|

Agree the price on the phone before an emergency callout, and ask whether they will drill. A skilled locksmith opens most domestic locks without damage; drilling first and charging for a replacement cylinder is the classic overcharge in an unregulated trade.
