  • Beautiful high-security locks – an elegant matching 3-lock door set comprising two high-security automatic deadbolt that automatically locks and a third 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.   
  • Multi-lock action for ultimate security – whilst the locks are traditional looking the 2 automatic deadbolts function like a multilock system securing your door at 2 places automatically every time the door is closed. This makes it ideal for urban areas or where convenient high-security is required.
  • Kitemarked insurance compliant – The automatic deadbolts are BS8621 certified and the manual deadbolt is BS3621 certified and kitemarked. All three 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 all 3 locks – all locks use identical TS2007 3 star ABS Avocet cylinders so one key opens all locks (say goodbye to your heavy keys!). The automatic deadbolts use thumbturns (so no keys required to exit in an emergency) and the manual deadbolt is key operated.
  • 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 night latch locks mounted onto the door, the FinBolt 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 presitigious 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.
