If you have a UPVC or composite door that is fitted with a multi-point lock you may think your property is safe and secure. Unfortunately your multi-point lock is only as secure as the euro-cylinder that is fitted to it. Thieves are now using methods to force entry such as lock bumping and lock snapping, this can take under 30 seconds to open your door. We can upgrade your euro-cylinder to an anti-snap, anti-drill, anti-pick cylinder which complies with British Standard BS EN 1303. We offer a survey to ensure all of your locks are up to insurance standards and recommendations, and offer free estimates on all of our work.

Love It, Lock It, some simple tips and advice to keep your property and contents secure.

  • Lock all windows and doors, even if leaving your home for just a few minutes
  • Keep valuables out of sight
  • Mark your property
  • Fit anti snap, anti pick and anti drill, bump resistant 'euro locks' on UPVC and composite doors
  • Don't let strangers into your building
  • Fit 5 lever BS3621 mortice locks to all wood front and back doors, and good locks to all downstairs windows and use them
  • Keep your house and car keys safe and away from doors, windows and letterboxes
  • Fit a letterbox cage to the back of your front door
  • Make sure you have up-to-date contents insurance

Excellent service, a choice of fittings, job was finished the same day. I would recommend Theakston Locksmiths for any locksmith work.

Mrs Wright, Queens Drive, Sedgefield

Mr Theakston has fitted two key safes for me and cut some keys. He is an experienced locksmith of many years standing and has done an excellent job.
He also has a lot of patience explaining how the system works and advising on the choice of equipment.
