Case depth, cylinder projection, handle centres and keep position are checked together. A new part is not forced into distorted or incompatible preparation.

Like-for-like describes compatible dimensions and function; it does not mean any visually similar lock will fit.
A decorative escutcheon cannot compensate for an unsuitable lock case. A warped door is not disguised by over-tightening the lock. Multipoint hooks rollers and deadbolts are tested through their complete travel. Security expectations are tied to the complete door and frame not one component.
Key requirements are confirmed before cylinders are ordered. A new position is quoted separately from a prepared replacement cut-out. The new case is seated to accurate depth with its faceplate flush to the edge. All supplied keys are counted and handed to the authorised customer.
Cylinder length is measured from the fixing point to both door faces. Authority to change the lock is confirmed before work starts. Fresh pilot holes avoid splitting timber or weakening previous preparation. Product packaging and identification details are useful to retain.
For the patio-door multipoint lock in Whitechapel, the brief begins with a handle that does not return cleanly; multipoint work depends on centres backset faceplate and gearbox details. Fire and escape requirements take priority over a generic security label. The keep is aligned with the latch or bolt while the door rests naturally in the frame. Any follow-on repair is stated before the team leaves.
Photographs narrow the options but final dimensions are taken at the door. The locksmith pauses if hidden construction prevents the agreed fitting. Waste and retained old hardware are handled according to the booking. Any remaining hinge or frame limitation is recorded clearly.
Glazing and panel positions restrict safe drilling zones. Finish and handing are confirmed on both sides of the entrance. Keys are tried from both sides where the product and access arrangement permit. Communal or managed doors may need approval beyond the installation visit.
Frame alignment must be considered before blaming new hardware. Supplied parts are checked before the door is altered. New cutting follows measured centres instead of enlarging an opening casually. The quote separates hardware fitting from door repair and decorative making good.
The keep position is checked with the door naturally closed. Multipoint components are matched to the connected handles and strip. The installation is tested first with the door open and then closed. Internal escape operation is demonstrated where relevant.
