unlock inner doorways with a fingerprint

Whether or not you wish to hold children out of your bed room otherwise you dwell in shared lodging and wish to hold your room non-public, a lock is the reply.

Historically, that meant a key-operated lock, or presumably a keypad lock should you wished to keep away from keys. However the fashionable door lock makes use of tech to unravel the issue. Simply as you possibly can unlock many telephones with a fingerprint, so you possibly can with Blusafe’s Breeze.

It’s IP65 rated for water resistance, however the Breeze is designed for inner doorways. You’ll be able to go for chrome, satin chrome and black finishes, and there’s a selection of a deal with with a round backplate that gives a contemporary look, however there’s additionally a ‘lengthy’ model that’s designed to cowl any present screw holes from a beforehand fitted deal with.

Options & design

Shops as much as 50 fingerprints
Key-operated backup
MicroUSB port for backup battery

Whichever mannequin you select, the Breeze is sort of chunky – it needs to be with the intention to accommodate 4 AAA batteries on the ‘inside’ deal with, and the motor, mechanical lock and different bits and items within the ‘exterior’ one.

I opted for the lengthy model so I might exchange an present deal with and conceal the screw holes. Because the picture exhibits, there’s fairly a distinction in measurement between the 2, and the 200x52mm backplate needs to be massive sufficient to cowl even holes from bigger older handles, together with these with a keyhole.

Blusafe despatched the satin chrome mannequin for overview, however even the polished chrome mannequin would not precisely match the opposite doorways with the smaller handles.

No latch is provided within the field: you utilize the prevailing one, or buy one from elsewhere should you’re becoming a model new door.

A useful QR code on the entrance of the guide hyperlinks to an additionally useful YouTube video that exhibits you precisely the best way to set up the Breeze.

Earlier than you begin the set up, verify if the handles are going through within the right path. If not, you’ll have to take away a screw or three on the within of the backplate, rotate the deal with 180° and pop the screws again in. I discovered neither the frequent PZ2 or PH2 screwdrivers fitted, and it’s a disgrace at this worth that Blusafe doesn’t present the proper screwdriver within the field.

It does present cardboard templates which you’ll fold across the edges of your door to make sure you drill holes in the fitting locations. However if you’re changing an present deal with and use the self-tapping screws provided, no drilling is required in any respect.

For a barely neater end, you possibly can as an alternative use the provided sleeves and snap-off screws in order that, on the skin at the least, there aren’t any seen screws. This feature does require drilling two holes by way of the door.

I selected the faster possibility of utilizing an influence driver with the self-tappers. The outer deal with have to be fitted first, feeding the connecting wire by way of the hole spindle (which replaces any present spindle). Only one size is provided, and it was the fitting measurement for my 35mm-thick door.

The within deal with can then be screwed on and, to complete, the wire have to be fastidiously related to the battery pack. A ending plate is hooked up with magnets and might be eliminated by pushing the provided pin by way of a gap behind the deal with.

One other gap in the long run of the deal with permits the pin to press the Set button on the top of the battery pack, and that’s the way you register fingerprints.

The primary three are ‘admin’ fingerprints and after these, there’s house within the reminiscence for 47 extra.

To register, you utilize the pin to push the Set button, which is on the top of the inner deal with, then press and take away your finger 4 instances on the sensor.

After the primary three fingerprints are saved, any further ones are ‘consumer’ fingerprints. To register these, an admin fingerprint needs to be scanned first, then a ‘consumer’ finger might be registered.

When the door is shut, the exterior deal with might be pushed down, nevertheless it gained’t transfer the latch. Solely when a fingerprint is recognised does the motor spring into motion to have interaction the spindle, at which level the deal with will function the latch.

You’ll want to press your finger on the sensor precisely as you probably did while you registered the fingerprint. Not like a cellphone, which asks you to scan your complete fingertip, the Breeze captures solely a portion, so it’s important to be considerably exact when urgent your finger to the sensor.

If somebody tries to unlock the door and their fingerprint isn’t recognised 5 instances inside 5 minutes, the deal with will sound a warning and cease scanning for 90 seconds.

As a backup, two keys are offered. The keyhole is in the long run of the deal with, and works simply as you’d count on. You inset the important thing, flip it 90° after which push the deal with down.

A secondary backup is a microUSB port on the reverse finish of the deal with. You’ll be able to join a typical microUSB cable to a USB energy financial institution to offer energy should you’ve allowed the AAA batteries to run flat.

They need to last as long as eight months, based on Blusafe, nevertheless it recommends altering them each six. You’ll hear a warning beep when working the deal with if the batteries are working low. At that time, it ought to work an extra 200 instances earlier than the batteries might be fully flat.


In testing, I discovered the Breeze labored effectively. It’s, as talked about, essential to put you finger on the scanner in the identical place and on the identical angle as you registered it. That’s why it’s essential when registering to put your finger as you’d naturally do it when strolling as much as the door.

The motor is pretty quiet and there’s no noticeable wait between scanning your fingerprint and with the ability to use the deal with – a few seconds on the most.

The LED ring offers visible suggestions: it lights up blue while you press your finger in opposition to the scanner, then inexperienced if it’s recognised or purple if not. And beeps do the identical factor in case the LED isn’t simply seen in shiny circumstances.

Construct high quality is excellent and although I used to be unable to confirm battery life, it’s going to largely depend on how typically the deal with is used. For those who hold the door shut on a regular basis, but additionally recurrently entry the room you could discover the batteries want changing sooner. Conversely, should you solely want to depart the door shut from time to time, or not often have to entry the room, they’ll last more.

Worth & availability

The Blusafe Breeze begins from £89.95 for the black mannequin, and goes as much as £104.95 for the lengthy mannequin in both of the chrome finishes.

You should buy a Breeze direct from Blusafe’s web site, nevertheless it’s additionally obtainable from Amazon for a similar costs.

It wasn’t obtainable within the US on the time of overview.


The Blusafe Breeze isn’t the most affordable biometric door lock, however most cost-effective isn’t sometimes greatest. It’s additionally fairly much more costly than, say, a £30 Yale push-button lock.

Keys might be copied, and codes might be found, however a biometric lock presents the benefit that it may be opened solely with the fitting finger. And, urgent your finger to the scanner is way sooner than keying in a six-digit code.
