Hi there, I’m looking for a reliable tradesperson to replace an existing door lock. The current setup is a standard mortise/coil type, and I’d prefer a modern secure cylinder with a one-year warranty. I have the new lock ready and compatible with a standard 60mm backset. Please bring your own tools, confirm security considerations, and let me know if you recommend upgrading strike plates or adding extra reinforcement. I’d like someone tidy, punctual, and able to handle both interior and exterior doors. Access is from a ground-floor apartment; parking is available nearby.
