Hi, I need a professional to replace the lock on my front door. The current cylinder is sticking and I’d like a secure, upgradeable locking system installed (preferably 5-lever mortice or modern euro cylinder with anti-snap features). The door is solid timber, and I’ll provide the new lock if you have a preferred model. Please include removal of the old hardware, ensure correct alignment, and test both the key and turning mechanism. I’d also appreciate advice on improving overall door security if possible. Availability this week would be great, and I’m aiming for a tidy job with minimal mess.
