I’m looking for a qualified locksmith to install a new door lock at my home. The job involves removing the old hardware, confirming compatibility with the current door and frame, and fitting a secure deadbolt plus strike plate. I prefer a lock with good security ratings (Grade 1 or 2) and keyless options if possible. Please bring the necessary tools, test the mechanism, and provide guidance on maintenance. I’d appreciate flexible daytime availability and a brief written estimate before starting. Location is within the UK; please confirm any travel fees and warranty on workmanship.
