Understanding FRIDAY products.

The DUO Smart Lock lets you open your door with your smartphone instead of your traditional key. The DUO Smart Lock communicates with your phone via Bluetooth, detecting when you are nearby and opening the door automatically if you have enabled this. DUO Smart Lock also allows you to give access to visitors remotely by sending them an invite via the app.

Yes. The DUO Smart Lock replaces your existing thumb latch, but leaves the remainder of your existing lock intact. This means that you will still be able to open your door in the traditional way from both the inside and outside.

The DUO Smart Lock takes up very little space on your front door, measuring 63mm / 2.48inch in width and 48mm/1.89inch in height.

The DUO Smart Lock uses a small rechargeable battery that reduces the size of the product substantially. In normal usage conditions the battery life is about 3-6 months before needing recharge. When the battery runs low, you will see an indication in the app. A USB charging cable is included in the package, and within 2 hours of charging it is 100% fully charged and ready to be reattached to your door.

As the DUO Smart Lock leaves your existing lock intact, you can always lock/unlock your door in the traditional way with a key (or from inside by just turning the shell). You can also login to your account in the FRIDAY app from a borrowed phone and control your lock.

The DUO Smart Lock retrofits most standard door locks. If any doubt, you are always welcome to take a photo of your existing lock that you wish to replace with a DUO Smart Lock and send to our support team.
