Old wooden door in Argentona: alignment or lock issue?

When an old wooden door is difficult to close, replacing the entrance lock should not be the first diagnosis. The symptom may lie where the leaf, frame and strike plate meet, or inside the cylinder and lock mechanism. Telling those possibilities apart prevents blind work and makes it easier to describe the issue accurately if a professional inspection is needed.

The local context is useful here for arranging a visit clearly, not for assigning a cause to the door. Argentona’s Pla Local de Joventut, a 2012–2016 municipal document, describes six neighbourhoods and residential concentrations including Argentona itself, El Cros, Madà and several housing developments. When requesting an on-site visit, it is sensible to provide the neighbourhood, street, access details and whether the issue affects the main door. For addresses near a boundary, the Generalitat provides official municipal-boundary mapping.

The most useful check needs no dismantling: with the door fully open, use only your own key and see whether it turns smoothly and whether the latch or bolts move without rubbing. Then close the door and repeat the same action without force. If the key turns freely when the door is open but becomes stiff only when it is closed, that normally points to misalignment between the lock and strike plate, or to the door leaf rubbing against the frame. If the key catches with the door open as well, the cylinder, lock body or key itself may be the focus; a worn copy can obscure the diagnosis.

Also look for visible clues: an uneven gap around the leaf and frame, fresh marks on the edge, a handle that does not return properly, or a latch that hits before it enters the strike plate. Do not force the key or handle past resistance, put household oil into the cylinder, or enlarge the strike opening without assessment. Those actions can turn an adjustment into a more serious fault.

The right repair follows what you observe. A professional can first assess hinge fixing, the door leaf’s seating and the strike plate’s position; where the fault occurs with the door open, the cylinder and mechanism should be checked before altering the wood.
