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

    FAQ - About our dual 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. 

    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.

    Yes! Any Finfort Locks can be keyed alike whether on the same door or different doors. A door lock set of two keyed alike deadbolts is not a standard product but we can arrange this for you. Just email contact@finfort.co.uk or call 0207 704 5287 and we can arrange it for you

    Yes, if you fit Finfort locks on another door at any time in the future, we can arrange for them all to be keyed-alike so one key opens all locks. Say goodbye to heavy bunch of keys!

    Our door lock sets come with one door pull as standard. The door pull is a plate that can be fitted to the internal or external side of the door though if you only have one, we recommend using it for the internal side.  If you have a door knob on the external side of the door, you do not need a door pull but you may choose to have it anyway for aesthetic reasons.

    What our customers say

    Automatic deadbolt is a great design

    We ordered a dual lock set in antique brass finish. Really happy with the quality of the locks and the automatic deadbolt is a great design, much more secure than the Yale night latch on our old door. The new solid wood front door looks fantastic and is much more secure. Great customer service from Hilary and Timothy, went above and beyond! Couldn't recommend FinFort more highly.

    Terrific find!!!

    The locks are excellent and very easy to fit and to use, and the customer service and delivery were prompt and also excellent. Hilary, particularly, extremely helpful.
    Their newly designed dead lock gives great peace of mind. They are a new company and I urge others to use them. Look them up and watch the video!!

    We're absolutely delighted with Finfort

    We’re absolutely delighted with FinFort locks for our new front door, not only their very smart appearance and choice of colours—we went for Antique Brass finish to match the rest of our Heritage Antique door furniture —but also absolute simplicity in using especially good for our children and smart functionality of one key for all locks! We were initially looking to fit the usual Banham locks but decided in favour of FinFort as they offered our preferred colour;-)
