Signs: the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally or the door closes poorly despite an otherwise sound visible opening. Causes: loose fixings, minor alignment drift or ordinary timber movement or local damage to an accessible component rather than an assumed structural defect.
Hardware must suit the leaf thickness and the maker’s permitted range. Spindles and fixings are not interchangeable solely because the finish matches. Provide the door specification where possible and keep the complete supplied pack together until the fit is reviewed.
The distance from the door edge to the operating centre affects compatibility. Share the product drawing and existing measurement if safely available. An incorrect backset can place the handle or mechanism against old holes, so check before purchasing a replacement.
adjust and retain suitable existing hardware. replace an identified compatible component after measuring the existing item. Limits: Authorised ordinary compatible mechanical lockset replacement only. No lockouts, emergency entry, key cutting, rekeying, locksmith security services, rated-door work or electrical integration.
