Door will not unlock
A turning key does not always mean every part of a door's locking system has released.

Door will not unlock — separate key, gearbox while alignment faults, with the surrounding frame, fittings and opening condition checked.
Describe the movement of the handle and any bolts you can observe safely. The investigation should consider connections and locking points across the door.
The detail that matters
Why does the key move but the door remain shut?
Another component may still be engaged, jammed or disconnected even though the cylinder can rotate.

Should I describe earlier intermittent faults?
Yes. Changes in handle feel, unusual noises or previous sticking can narrow the assessment.
What should I include in this enquiry?
Have the postcode, photographs of the lock and door, and a short account of when the fault began. Identify the person authorised to arrange access; do not send key codes or sensitive entry credentials through the form.
