The front door of a shop gets cleaned, inspected and admired. The delivery door gets kicked open with a boot forty times a day from October onward. By December the closer has given up, the latch no longer engages and it stands open through every delivery. That's the door worth spending an hour on before the season starts.

A duplicate cut from an already-worn key inherits that wear, then adds its own. A few generations later the key jiggles, sticks and eventually strands you — and everyone blames the lock. The answer is cutting to the original code, or decoding the cylinder, rather than tracing a tired key. Chip keys cloned and programmed properly, and a whole house or office keyed alike on request.

If you lift, slam or shove the door to turn the key, the bolt isn't seating — it's catching the lip of the strike instead of dropping into it. Summer humidity swells the slab and the hinge screws back out a couple of millimetres, so people blame the lock. We reset the hinges with screws long enough to bite the stud, re-cut the strike and fit a box strike. Half an hour, before winter.
