Top tips
Hiring a locksmith, without the regret.
Four moves that separate a smooth job from a nightmare.
Cylinder Protrusion
If the lock sticks out more than 3mm from the door handle, it can be easily snapped with basic tools.
Misaligned Keeps
If you have to "heave" the handle up to lock a uPVC door, the mechanism is under stress and will eventually fail.
Poor Quality Duplicates
Keys cut from "clones" rather than originals can have slight variations that wear down the lock pins prematurely.
Weather Swelling
Timber doors can swell in winter, causing the lock bolt to stick; a locksmith can adjust the "strike plate" to fix this.
Costs & timeline
Know what it costs. Know when it ends.
