  • 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 – 3 star ABS MASTER 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 (i.e. putting the lock 'on the latch'), handy for loading and unloading the car, for example.

    FAQ - about our triple door lock set

    An automatic deadbolt automatically locks the door with a solid deadbolt every time the door closes. The lock mechanism has a connected trigger and bolt action: when the trigger makes contact with the strike plate in the door frame, the lock throws the deadbolt to secure the door automatically. 

    An automatic deadbolt is more secure as a thief cannot slip it as they could latch, and you can’t forget to lock it as you would a manual deadbolt.  Therefore, you never make your home an easy target for an opportunist thief. 

    Firstly, the Finfort automatic deadbolt throws an 11mm thick by 21mm long solid hardened steel deadbolt on door closure.

    Secondly, it is morticed into the door which is much more secure than a side mounted lock.

    Finally, it has a unique patented feature: when a Finfort automatic deadbolt is unlocked, the deadbolt retracts and is held by an ‘internal holdback’ which temporarily keeps the deadbolt in an unlocked position while the key is removed to open any other locks on the door.

    This means that it is possible to fit two automatic deadbolts on the same door that can be opened in any order with one key using one hand.  This superior functionality is unique to Finfort Locks and was awarded prizes by both the Master Locksmith Association in 2019 and the Society for British & International Design in 2021.

    No! This is one of the unique and patented features of the Finfort automatic deadbolt. The innovative configuration of levers and springs in the lockcase mean that each deadbolt can be opened and will stay open in the door frame while other locks are opened. Therefore locks can be opened in any order with one hand with the same key.

    Use this text to answer questions in as much detail as possible for your customers.

    Yes, Finfort automatic deadbolts are particularly well suited to outward opening doors.  A latch lock on an outward opening door can be easily opened.  A Finfort automatic deadbolt greatly reduces this vulnerability as a solid bolt cannot be easily manipulated, even when the bolt is visible. On an outward opening door, because our locks include a deadbolt tumbler feature so that the deadbolt cannot be forced backwards when in the locked position, even under a very substantial backwards force.

    Still going strong a year on

    I called up and they were genuinely helpful, not pushy at all, and helped me choose the right mix of locks and customise the set so it looks great on both the outside and inside of the door. Nearly a year of daily use later, they still look superb and work flawlessly, no problems whatsoever. Splendid products, and I'd recommend looking at Finfort to anyone.

    A game changer for shared doors

    Finfort makes award-winning high-security locks to BS3621 or BS8621 with a 3-star cylinder, all UK-made. They've matched the design and action of an Ingersoll SC71 with a mortice lock that automatically locks the instant you shut the door, so the door is secured every time it closes, ideal when the house is empty, and reassuring when you're home too. It's especially good for communal and shared front doors, and the version for outward-opening doors solves a problem rim locks can't.

    Two deadbolts, never a second thought

    These locks are genuinely impressive, I'd looked around for a while and nothing I found compares. They're very well made and reassuringly strong, exactly as a lock should be. I fitted two automatic deadbolts to my door, keyed alike, and now never give it a second thought: the door bolts itself every time I close it. Inside there's no bulky, unsightly nightlatch, just a neat lockguard and thumbturn, and from outside it clearly reads as high-security, which is a deterrent in itself. Worth every penny for the peace of mind.
