Frequently Asked Questions — Cardiff
-
What does a lock change cost in Cardiff?
Single euro cylinder swaps run £89 to £119. BS3621 mortice deadlocks sit at £129 to £159. Pairing a front and back door together usually saves £20 to £30.
-
Should I fit anti-snap cylinders?
If you have uPVC or composite doors, yes. Standard cylinders can be snapped in under 30 seconds. A 3-star Kitemarked anti-snap cylinder defeats that attack and is what most CF postcode insurers expect.
-
Can you match all my doors to one key?
Yes. We supply keyed-alike sets so a single key opens front, back and any side doors. Useful for terraced houses in Roath or Cathays where multiple entry points share a key.
-
Do you keep older lock styles in stock?
Vans carry stock for Victorian rim locks, Edwardian sashlocks, modern Yale, ERA, Avocet and Brisant. If something exotic is needed we'll order it and return the same week.
-
How long does a typical lock change take?
A like-for-like cylinder swap is 15 to 20 minutes. A full mortice deadlock fit on a timber door takes 45 to 60 minutes including any chiselling.
-
Will new locks come with a certificate?
Yes. We email a certificate of installation listing the British Standard rating, useful for home insurance renewals or landlord records.
-
Can you fit smart locks?
We install Yale Conexis, Ultion Nuki and similar Bluetooth and keypad locks. Worth noting that not all smart locks meet BS3621, so check your insurance terms first.

-
Got home from work in Llandaff to find my key wouldn't turn at all. Cylinder had failed internally. New one fitted in twenty minutes for £89.
-
Landlord asked us to change the locks after a previous tenant didn't return keys. CF11 flat, two doors, done inside 90 minutes for £179 with five keys cut.
-
Dropped keys down a drain in Riverside coming back from town. Got us back inside by 1am and rekeyed the door in the morning so the old set was useless. Clean, professional work.
-
Tidy job. Locked myself out in Splott on a Sunday morning, phone showed the engineer 14 minutes away and that's exactly what happened.
