Bring your home security in line with your modern life, with a Gainsborough Freestyle Electronic Trilock.

Keys to the castle

A good lock is the most effective way to keep your family and property safe. But modern locks, like the Gainsborough Freestyle Electronic Trilock, offer so much more than simple keyed versions, giving unprecedented control and ease of use. 

Free and easy

Imagine living life unencumbered by keys. With a Gainsborough Freestyle Electronic Trilock, you can travel lighter, unlocking the door with the keypad or with an app on your smartphone (iOS available, Android coming soon).

There's no need to distribute multiple keys to family, friends or tradies, or to hide them around your property. You can assign, invite and schedule up to 20 users, and just as easily remove them when you need to.

Making the switch to a smarter system is simple; Gainsborough Freestyle Trilocks can be very easily swapped with your existing Trilock, or with many other locking mechanisms.

Peace of mind

You can never be completely certain of what's happening at home while you're out. Is someone MacGyvering their way into your house? Are you sure you remembered to lock the door in the first place?

The Gainsborough Freestyle Electronic Trilock covers all the usual modes of locking – passage, privacy and deadlock – but with an added layer of smart security; when paired with the optional door sensor kit, the app can tell you if the door is open or closed, from wherever you are. 

Remote control

Being able to let in guests from afar is an obvious advantage, but there's more! Imagine being able to manage your holiday rental from anywhere in the world, adding or removing access to the home from your smartphone.

The Gainsborough Freestyle Wi-Fi bridge and door sensor makes it simple to control your Trilock from wherever you are, via the Gainsborough Freestyle app.
