Replacement and renovation
When something fails or a door is being refreshed, the aim is usually to reuse the holes and pockets already in the door. That depends on careful measurement.
Plan it as a set
Start with the old part
Bring it, or photograph it beside a ruler, including any markings.
Measure before you buy
Backset, door thickness and the centre distance between handle and key hole decide what fits.
Cover old marks
A larger plate or rose can hide old screw holes when the style changes.
Check the strike
A door that will not latch is often a strike plate problem, not a lock problem.
Where to look in the range
Replacement cylinders, spindles, strike plates, screws and closer parts: bring the old part.
Mortise lock sets, rim and safety locks, cylinders and knob locks for main and interior doors.
Lever handles on roses or plates, pull handles and knobs, matched to the lock.
Butt, ball-bearing and other door hinges, chosen by door weight, size and finish.
