When should I change the locks on my Swansea home?

After moving in, following a break-in or attempt, when a key goes missing, or when a tenant moves out of a let. On the older Uplands and St Thomas terraces we often find worn mortice locks that are well past their best and worth replacing while we are there.

Do your lock changes meet British Standard for insurance?

Yes. We fit BS3621 five-lever mortice locks on timber doors and TS007 or Sold Secure anti-snap euro cylinders on uPVC and composite doors. Most home insurers in the SA area specify BS3621 on final exit doors, and we can point it out on your policy if you are unsure.

How much is a lock change in Swansea?

From £88, depending on the lock. A euro cylinder swap on a Sketty uPVC door is at the lower end. A British Standard mortice fitted to an older Brynmill timber door costs more because of the cutting and fitting. You get the price before we start.

Can you change just the cylinder rather than the whole lock?

Usually, yes, and it is the cheaper route. On most uPVC and composite doors the euro cylinder pulls out and a new one goes in without touching the rest of the mechanism. That is the go-to for landlords doing a changeover on a Brynmill student let.

I am worried about lock snapping. Can you fit anti-snap cylinders?

Yes, and we recommend it on any uPVC or composite door. Cylinder snapping is a known method burglars use on the newer estates around Llansamlet and West Cross. A three-star anti-snap cylinder resists it, and the upgrade is quick and affordable.

Can you match all my Swansea locks to one key?

We can key-alike your cylinders so one key runs the front and back doors. Handy on the terraces where people are juggling three keys for one house. We set that up when we change the locks.

Do you change locks on flats in the SA1 marina?

Yes. The waterfront apartments mostly use euro cylinders on the flat door plus a communal entry system at the block. We swap the flat cylinder easily, and can advise on the communal side, though that usually needs the managing agent's sign-off.

What Our Customers Say

Salt air off the bay had seized the lock on our Mumbles cottage. He serviced it and swapped the cylinder for one that copes better near the sea. Sound advice. £88.

Bethan L. Lock change
Old five-lever mortice on our Walter Road flat had seized solid. He drilled it, fitted a new British Standard one and cleaned up after himself. £125. Good job.

Ceri A. Lock change
Slammed the door behind me at my Brynmill student house with the keys inside. Half two in the morning. He was there fast and got me in without breaking anything. £70. Lifesaver during exams.

Ffion W. Emergency lockout
Our uPVC back door in Sketty stopped locking properly, had to lift the handle really hard. Turned out to be the gearbox. New mechanism fitted the same afternoon for £120. No fuss.
