Most residential and commercial door locks fall into one of a few families — Euro cylinder, mortice, night latch, or multi-point uPVC. ASG Locksmith carries the common variants on the van so most jobs are finished in a single visit.

What this service covers

  • Euro cylinder replacement (including anti-snap 3-star)
  • Mortice deadlock and sashlock repair or upgrade
  • Multi-point uPVC gearbox replacement
  • Night latch (Yale-style) fitting
  • British Standard BS3621 upgrades for insurance compliance
  • Rekeying and matching multiple locks to one key

Who this is for

Anyone who's lost a key, changed hands with a property, been let down by a cheap DIY lock, or been asked by their insurer to upgrade to a British Standard lock.
