We are an independant (non-franchised) locksmiths business, based in St Austell and covering the whole of Cornwall.


The services we offer:

  • Lock opening service (household, commercial & vehicle) - for people who have lost their keys or simply locked themselves out.  We specialise in opening failed multi-point locking mechanisms
  • Lock changing & installation - it is always a good idea to change your locks when you move into a new home or between tenants if you have properties that you rent out.  Anyone can get a key copied if they have access to the original and there is no way of knowing how many copies exist
  • Broken key extraction - keys can easily become bent, which will considerably weaken them.  Straightening will weaken them further and if used, they are likely to break - usually inside the lock!
  • Boarding up service - making broken windows or doors temporarily secure and weatherproof, until permanent repairs can be made



We also carry out repairs to uPVC windows and doors, including:

  • Door & window hinge, lock & handle adjustment, repairs and replacement
  • Opening & repairing failed multi-point mechanisms
  • Vent and trim replacement
  • Replacement of clouded sealed glazing units
  • Letter plate replacement
  • Repairs to cracked, split or holed plastic
  • Adjustment & replacement of sliding patio door rollers
  • Gasket & sealant replacement
  • Security upgrades and improvements

  • Cable and cone repairs / replacement
  • Roller replacement
  • Spring tensioning
  • Handle repairs / replacement
  • Lock opening, replacement and repair
