Frequently Asked Questions — Southampton
-
How much for a Southampton lock change?
Single euro cylinder swap from £89. Anti-snap upgrade £119 to £149. Full BS3621 mortice fit on a timber door £149 to £189.
-
Should I upgrade to anti-snap on a uPVC door?
If your door has a euro cylinder and the cylinder isn't 3-star TS007, yes. Lock-snapping is the most common forced entry on uPVC. £119 buys real protection.
-
Do Victorian terraces in Portswood need anything special?
Most SO15 and SO17 Victorians have timber front doors with traditional mortice locks. We replace with BS3621 5-lever mortice, which fits the existing chase. The door doesn't need any modification.
-
Can I have one key for every door?
Yes. Ask for keyed-alike at booking. Front, back, garage, side gate all share a single key.
-
Does this satisfy my home insurance?
BS3621 on timber and TS007 3-star on uPVC are the usual policy requirements. We label the invoice with the standard so you can attach it to a claim.
-
How long is the engineer on site?
Single cylinder, 20 minutes. Mortice change, 45 to 60. Whole house including matched keys, two hours.
-
Is rekeying cheaper than replacing?
On euro cylinders, no, the labour and pins cost as much as a fresh cylinder. On older mortices we can repin if the lock body is sound. Cheaper for you when it's possible.
