Good to know
- The night latch is not included: it suits doors with a 60 mm night latch.
- Passcodes need the Wireless Keypad, sold separately.
- Measure first: you need at least 2.5 cm between the centre of your cylinder and the door frame.

Before you buy Every worry, handled.
The questions everyone asks, answered plainly, because peace of mind starts before you buy.
Is it compatible with my door?
It's suitable for doors with a 60mm nightlatch. (Nightlatch NOT included).
Are any electrical connections necessary to install an electronic cylinder?
No electrical connections to the door are needed as it is powered by long-life batteries. The user is warned when the battery charge is low by both the lock and app.
Do I need the Simpled Gateway?
Without the need for a gateway, you have the convenience of sharing smartlock access with your smartphone. However, when combined with a Wireless Keypad and Gateway, you gain the ability to remotely share and delete passcodes for guests, cleaners, and repair services from anywhere in the world.
What happens when the lock is out of battery?
In the event of the battery failing, there is a further fail-safe, thanks to a USB-C battery connection override.
If someone steals a family member's phone, can they get into my house?
If a smartphone is lost or stolen, it can be deactivated by the admin user. This means that security against unauthorised entry is still ensured without changing the lock.
Is this smart lock weatherproof?
Yes, it is.

Great company that care. I used them on my first airBnB property and have now rolled them out to two more. The after sales service is what really stands out. Advice, spare parts, tech support all 100% ?
Owen Werakso · January 2026 Very reliable and support is fantastic. They have everything in order and you can feel it in their service and aftermarket. Different and refreshing with great products, highly recommended.
Elias Gadgets (Gary) · December 2025 Great smart lock. Absolutely brilliant after sales service.. I had some questions during installation. Simpled got back to me very quickly and talk me through it.
