I’m looking for a reliable locksmith to diagnose and fix a faulty door lock at my home. The main issue is a stuck or hard-to-turn key and a loose strike plate causing misalignment. I’d like a same-day or next-day visit if possible. Please include a quick assessment, replace or repair the cylinder if needed, and ensure the door closes securely. Access will be available, and I’d prefer a technician who uses up-to-date locking hardware and can provide a basic warranty on parts and workmanship. I’m in a listed building, so a discreet, respectful approach to the hardware and surrounding decor is appreciated.
