Our Residential Locksmith Services
Emergency Home Lockouts
Locked out of your home in Belfast? We respond 24/7 with a 15-20 minute response time across the city. Using professional non-destructive entry techniques, we get you back inside without damaging your door, frame, or lock.
Whether it's 3am on a Sunday or Christmas morning — we answer and we're on our way.
Lock Changes
Moving into a new home is the most important time to change your locks. Previous owners, estate agents, builders, or contractors may still have copies of the keys. We provide professional lock changes across Belfast, upgrading to high-security anti-snap cylinders that protect your home from day one.
We also provide lock changes after:
- Relationship breakdowns
- Lost or stolen keys
- Tenant changes (for landlords)
- Break-ins or attempted break-ins
- Keys that have been copied without your knowledge
Lock Repairs
Stiff lock? Key that won't turn properly? Handle that's dropped or feels loose? We repair all types of residential locks across Belfast — Yale locks, euro cylinders, UPVC multipoint mechanisms, mortice deadlocks, and more. We always try to repair before recommending replacement.
UPVC & Composite Door Repairs
UPVC and composite doors are standard across Belfast's housing stock. When the multipoint locking mechanism fails — door won't lock on all points, handle droops, key won't turn — we diagnose and fix on the spot. We carry common UPVC mechanisms in our van for same-day repairs.
Security Upgrades
Want better protection for your family? We assess your current locks, identify vulnerabilities, and recommend targeted upgrades — anti-snap cylinders, BS3621 mortice deadlocks, window locks, reinforced strike plates. Honest advice with no sales pressure. Free assessment available.
Post Break-In Repairs
After a break-in or attempted break-in we respond as an emergency, secure your property, replace damaged locks, and upgrade security immediately. A break-in is traumatic — we work quickly to make your home secure again.
Shed, Garage & Outbuilding Security
Garden sheds and garages are often the weakest security point on a property. We install quality padlocks and security hardware on outbuildings across Belfast.
Window Lock Installation
Ground floor and accessible windows without locks are a common entry point for burglars. We install window locks across all window types quickly and at low cost.
We Know Belfast Homes
From Victorian terraces in the Holylands and Stranmillis to modern UPVC-doored new builds in Dundonald and Newtownabbey, older properties in South Belfast to apartment blocks in the Titanic Quarter — we've worked on every property type across the city.
Different properties have different locks, different door types, and different security needs. We carry the parts and experience to handle them all.
