door lock replacement can be appropriate when the door sags, rubs, sticks or has uneven gaps around the opening. Confirm authority, mechanical compatibility and existing cut-outs before accepting a lockset swap on an accessible door.
Signs: the door closes poorly despite an otherwise sound visible opening or the door sags, rubs, sticks or has uneven gaps around the opening. Causes: local damage to an accessible component rather than an assumed structural defect or normal wear in hinges, latches or compatible mechanical hardware.
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.
Keep the strike, fixings, instructions and all compatible fittings with the new lockset. Missing components can prevent installation even when the main body is present. Do not assume unrelated spare screws or old fittings will meet the new product’s requirements.
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.
