  • Beautiful high-security locks  – an elegant matching 2-lock door set for classic British front doors with one high-security auto-deadbolt nightlatch that automatically locks without turning a key and a second insurance-compliant, key-operated manual deadbolt you choose when to use.  
  • High-security cylinders – are designed to resist to attack by snapping, picking, drilling and bumping.  They are Secure by Design Accredited and Sold Secure Diamond Grade.   
  • Kitemarked insurance compliant – The automatic deadbolt is BS8621 certified and the manual deadbolt is BS3621 certified and kitemarked. Both locks have a 21mm steel bolt that can withstand 10kn of force and a hardened steel lock case that can withstand 5 minutes of constant drilling.  
  • Registered keys offer the highest security – keys cannot be copied without permission. Additional keys can be ordered online by key card holders only.
  • One key opens both locks – both locks use identical TS2007 3 star ABS Avocet cylinders so one key opens both locks (say goodbye to your heavy keys!). The automatic deadbolt uses a thumbturn (so no keys required to exit in an emergency) and the manual deadbolt is key operated. Locks can be opened with one hand in any order.
  • Reliable long life assured – these locks have been tested 200,000 times (that’s about 20 years of use for an average house) to achieve their EN12209 certification and why we guarantee them for 10 years.
  • Heavy duty lockguards– adding extra protection to the cylinders against tampering and act as a visual deterrent to a burglar.
  • Sleek & elegant design – unlike bulky nightlatch locks mounted onto the door, the auto-deadbolt nightlatch is embedded into the door so is a more elegant solution suitable to period or modern homes.
  • Award-winning design – the FinBolt automatic deadbolt was awarded ‘Best Product’ by the Master Locksmith Association in 2019 and won a prestigious SBID design award in 2021.
  • Deadbolt disabler for your convenience – built-in snib button to temporarily disable your deadbolt, handy for loading and unloading the car, for example.
