A reputable locksmith handles emergency lock-outs, lock changes, UPVC door repairs, burglary damage, and safe opening or installation. In Northern Ireland the trade is not statutorily regulated, which makes vetting more important — anyone can call themselves a locksmith. Master Locksmiths Association (MLA) members have been DBS-checked, inspected, and required to hold public liability insurance, so the MLA register is a useful starting point. Always ask to see ID before letting a locksmith into your property.

Frequently asked questions
How quickly can a locksmith reach me if I am locked out?
Most NI locksmiths advertise a 30–60 minute response in Belfast, Lisburn, Bangor, Newtownards and the surrounding urban belt. Rural callouts (Fermanagh, Tyrone, parts of Mid-Ulster) can take 60–90 minutes. Ask for an honest ETA before agreeing the callout, and confirm the total price including the callout fee and any out-of-hours surcharge in writing or by text before they set off.
My UPVC door will not lock — do I need a new lock or can it be repaired?
In most cases a UPVC door that has stopped locking can be repaired without replacing the lock itself. The most common cause is the door dropping or the frame shifting, which puts the multi-point mechanism out of alignment. A good NI locksmith will check the alignment first, adjust the hinges and keeps, and only quote for a full mechanism replacement if the gearbox itself has failed. Expect £60–£140 for a re-alignment, or £140–£280 for a new mechanism.
After a break-in, what should I replace?
Replace every external lock, not just the lock that was damaged. The intruder may have copied keys or compromised others. Most NI home insurers require external doors to have BS3621-compliant locks, and they will check this when paying out a claim. After any forced entry have the door frame, multi-point mechanism and locks all inspected, ask for written confirmation of the upgrade for your insurer, and keep the invoice.
Is a locksmith vetted? How do I know they are legitimate?
The trade is not statutorily regulated in the UK, which is exactly why vetting matters. Look for Master Locksmiths Association (MLA) membership — MLA members are DBS-checked, inspected, and insured. Ask for ID at the door. A trustworthy locksmith will be happy to show it. Avoid anyone who refuses to provide a written price before work starts. NI Trades vets identity, insurance and references at application stage, but on the day of hire you should still ask to see ID, the MLA card if claimed, and a current insurance certificate before letting them in.
Important
After a burglary or a lost set of keys, change every external lock — not just the one that was used. Most NI homes have multiple entry doors and a single missing key compromises all of them.
