Lock Replacement & Security Upgrades in Swansea
Whether you've just moved in, lost a set of keys, ended a tenancy or had a lock start sticking, changing the lock is quick, affordable and gives you back full control of who can get in.
What's included
- Same-day lock changes across Swansea and 15 miles around
- Anti-snap, anti-bump, anti-drill euro cylinders (TS007 3-star)
- British Standard BS3621 mortice locks for insurance compliance
- Keyed-alike sets so one key opens front, back and garage
- Old lock removed and disposed of, new keys handed over on the spot
When you should change a lock
Move into a new home and you have no idea how many keys are in circulation — previous owners, tradespeople, family, old tenants. Changing the cylinder on day one is the cheapest peace of mind you'll ever buy.
Other clear triggers: keys lost or stolen, a relationship or tenancy ending, a break-in or attempted break-in, a key that has started to need jiggling, or an insurer telling you your door does not meet British Standard.
Anti-snap cylinders and why they matter
Lock snapping is still one of the most common ways uPVC and composite doors are attacked in South Wales. A standard euro cylinder can be snapped in seconds with basic tools. A TS007 3-star or Sold Secure Diamond cylinder is built with sacrificial sections so the outer part breaks away and the lock stays secure.
If your cylinder currently sticks out more than a couple of millimetres past the handle, it's an easy target. I can measure it and fit a correctly sized anti-snap replacement the same visit.
Insurance-approved mortice locks
Most home insurance policies require a BS3621 five-lever mortice deadlock on final exit timber doors. If yours isn't marked with the British Standard kitemark, a claim can be disputed. I fit kitemarked locks that meet the requirement and can point out the marking so you can note it for your policy.
Lock Replacement & Upgrades — common questions
Can you change a lock without replacing the whole door mechanism?+
Usually yes. On uPVC and composite doors the euro cylinder can be swapped on its own, which is far cheaper than a full multipoint gearbox. I'll only replace the mechanism if the gearbox itself has failed.
Can I have all my doors on one key?+
Yes — keyed-alike cylinders mean one key opens your front, back and garage doors. It's a popular upgrade and costs very little extra when done at the same time.
Do you supply the locks?+
I carry a stock of quality cylinders, mortice locks and nightlatches in the van, so most jobs are completed in a single visit.
I've just moved house — should I change the locks?+
I'd always recommend it. You have no way of knowing how many keys exist for a property you've just bought or rented, and a cylinder change is a small cost for complete control.
