How We Replace Your Lock
From door assessment to a final security check — here's exactly how it comes together.
Door & Hardware Assessment
We check your door type and existing bore so the new lock fits cleanly, with no gouging or filler needed.
Old Hardware Removed
The old knob, lever or deadbolt is removed, and the door is checked for any damage around the strike area.
Grade 1 Lock Fitted
The new lock is fitted with a reinforced strike plate and 75mm security screws for real pull-out resistance.
Keys Cut & Tested
Keys are cut on-site if required, and the lock is tested through a full cycle to confirm smooth operation.
Security Check & Handover
A final security check on the whole door, plus a walkthrough of anything else worth upgrading.

“Locked out at 9pm and they had a new deadbolt fitted within the hour. Grade 1 security, not some flimsy replacement.”
Trent B. — Marion
“Upgraded every external door to matching Lockwood deadbolts and got them all keyed alike. Clean work, no drama.”
Yuki H. — Norwood
“Multipoint lock on our aluminium door was seizing up. Replaced the whole mechanism and it's smoother than when it was new.”
Connor S. — Aldgate
