Subsystem Main Function Common Wear Points Hinges Support the door leaf and permit rotation Spring cassettes, adjustment screws, cam journals Multi‑point Lock Engage deadbolts and shoot bolts into the frame Transmission, lock, keep, hinge‑mounted shoot bolts Handle & & Cylinder Send manual force to the lock mechanism Spindle, lever, Euro cylinder, dealings with When any of these parts misalign or become used, the door may stick, draught, or stop working to lock appropriately.
