Lock Rekeying & Replacement in St Marys
St Marys rekeying and lock replacement — mobile, and on call around the clock.

Newer infill townhouses off the side streets bring keyed-alike restricted systems and, increasingly, keypad handles. We reach St Marys in about 40-55 minutes, quote before we start, and work non-destructively wherever the lock allows.

Local knowledge
Rekey & Replacement built around St Marys
St Marys is split in two by the Western line: a walkable retail strip and postwar cottages to the south, and the Dunheved industrial estate's workshops and yards to the north. The two halves want completely different lock work, and they sit five minutes apart.
South of the line the housing is old enough that plenty of front doors still run their original mortice lock and a separate key for the screen. Newer infill townhouses off the side streets bring keyed-alike restricted systems and, increasingly, keypad handles. It is the difference between arriving at the Queen Street shopping strip with the right cylinder on board and arriving with a catalogue.
St Marys is postwar fibro and brick cottages south of the line, with townhouse and dual-occupancy infill filling the older blocks, and the hardware follows the era of the door. We see the same pattern right across St Marys and through North St Marys and Oxley Park, so nothing about a St Marys call is a surprise.
