Check the accepted mechanical hardware with the door open and then in its ordinary closed position. The authorised customer should understand the supplied product’s operation. This is a fitting check, not a security assessment, compliance certificate or promise against unauthorised entry.
Photograph the edge preparation and both door faces. A different lock body may require work beyond a straightforward compatible swap. Structural alteration, rebuilding damaged sections and specialist door-system changes are excluded rather than assumed to be part of replacement hardware fitting.
The strike needs to suit the latch and existing frame. A replacement lockset will not automatically correct a sagging door or damaged jamb. Any ordinary adjustment or separate repair should be identified in the quote before testing final closing and operation.
Replace suitable ordinary mechanical hardware in the compatible existing preparation and check its operation with the authorised customer. Scope limits: Authorised ordinary compatible mechanical lockset replacement only. No lockouts, emergency entry, key cutting, rekeying, locksmith security services, rated-door work or electrical integration.
