We.Lock SECB test: a smart fingerprint lock, among others ...

In the family of smart locks, there is several possible choices : replace the entire lock, only the cylinder, with code, fingerprint, connected or not… In short, not simple and above all, at all prices. The most successful means of securing seems to be papillary recognition. Unless you go out without your fingers, vYou will always have your keys with you. We have therefore sought for you the fairest quality / price ratio with optimal security. Our choice fell on one of the major players in the sector and its We.lock ECBC, sold for around € 105, easy to install (a simple change of barrel) and operating by fingerprint detection, but also Bluetooth and RFID. It is one of the cheapest on the market.

We.Lock SECB: a smart lock with fingerprint reader


The Chinese brand We.Lock, created 10 years ago, is one of the market leaders in security locks. Almost unknown in Europe, it seeks to establish itself there by adapting its models to the locks of the old continent. Moreover, "key" comes from the Latin " clavus' (nail), because initially the lock was simply a nail passed through a ring.

It is more specifically the reference We.Lock SECB 0EBL01 that we tested. The brand announces a compatibility with more than 99% of European locks, but it is necessary to do some checking. We are talking about a lock, but we are actually more in the presence of a connected cylinder. The latter is delivered in a blue box with window allowing to see the product. No reference, specification or particular explanation. It's sober, very sober. Note that the whole is almost 600 g and measure 22,5 x 14,5 x 7 cm.

The interior consists of several layers of dense foam in order to secure the product. You also see a number of accessories and tools. You also have under the lock a small black box with the installation kit.

What is the pack made of (each reference giving rise to a different pack)?

  • Un installation booklet, including a part in French which looks like French. And for once, pretty well done to use the lock 100% locally (without Bluetooth). However, the last part, relating to emergency opening (in case of dead batteries) is in Chinese, Arabic and English. To note that for the installation of the barrel in Bluetooth, it is totally wrong !
  • We.Lock stickers : they are not terrible, are useless, but are quite funny. We all know people like that ...
  • 3 RFID cards,
  • The installation kit containing: two Allen keys and two grub screws advance in case of loss.

Made in 304 stainless steel (one of the most resistant but also not the one that ages the best), made of aluminum alloy and plastic, the We.Lock SECB connected lock is 408 g. The barrel is in barrel of 30 + 40 mm (33 mm high). This can therefore be used on the majority of locks in France. But be careful, if your bit (and not Panettone) is totally off-center, it will not pass (it will not fall in line with your door), ditto if it has a specific shape (star, etc.). Use the following diagrams as a guide.

The barrel is extended on each side by square rods on which handles are inserted. Each one does 5,7 cm long by 4,4 cm in diameter. You can come and adjust the positioning of the latter up to 10,5 cm spacing. To do this, use one of the Allen keys to unscrew the grub screw of the inner handle (the one without the sensor). For the one with the sensor, it's a little more complicated: remove the battery cover and unscrew the screw inside this cover. The interior pommel can be completely removed, but not the exterior. Which makes sense. The minimum spacing is therefore 70 mm, corresponding to the size of the barrel.

The lock therefore has a fluctuating length of 18 to 23,5 cm.

This reference offers you, as advertised, a fingerprint opening system, among others. We also tested some time ago the version with code. Both systems have advantages and disadvantages. Let's say the fingerprint system is faster to use, but in case of wet fingers (see our video), injuries, it will work less well. Ditto, it will not be possible to make temporary accounts remotely. The code system is less stylish, less trendy and takes longer to use (you have to enter the code). But no problem of unreadable imprint and there is the possibility of creating temporary accesses with ephemeral codes. And this is perfect for those doing rentals. There are also hybrid systems.

We.Lock Soho: the multi-media connected lock

The touchpad is on the top side of the outer grip. You have a "Power" button who will make it possible to do wake up the module to save batteries. The fingerprint sensor has a 360 dpi resolution (152 x 200 px). There is a small screen above 17 x 5 mm OLED. Very simple, but thanks to its backlight you will be able to access the settings.

In terms of finishes, the brand could do better. Indeed, we have scratches on the inner handle still virgin of any greedy hand ... Similarly, the inner counter screw of the outer handle has also come loose during an adjustment. Cannot install batteries. We had to put it back in place with pliers… Too bad. Apart from that, we have a real sense of security. The barrel Super B and Bank Level certified. These are US security level recognitions. The worse the grade A, the better the C, the Super B is just before the latter.

Le Bank Level means that it can be used (in terms of security) in a bank. Thus the barrel will not be dismantled with a drill and hammer in less than 15 seconds. Having said that, if you put the lock on an unreinforced door, it will be easier to kick it out than to force the barrel.

We.Lock SECB: installation and use

Installing the smart lock

First of all, you will have to install the batteries and then install the lock. It takes just 5 minutes. To install the batteries, unscrew the grub screw on the right side of the handle with sensor. Remove the metal cover. Slide the "cover" plastic to reach the battery compartment. As seen earlier, you will also find another grub screw there which will make it possible to modify the degree of depression of the handle on the square rod. Once the batteries are in place, you will hear a "beep", the screen will backlit and it's good.

Then come and remove the interior handle (the very simple one) by unscrewing the grub screw with the larger Allen key. So you have at this level, a bare square rod that will be able to be inserted into your door.

For the rest, open your door and unscrew the large retaining screw, which you usually find under the bolt of your door, on its edge. Keep the screw tight because it is the one that you will use to come and re-fix the cylinder. Remove your old lock (just the cylinder) and insert the new one, starting by inserting the square on the inside handle side (therefore pushing it from the outside to the inside). Put the cylinder in line with the bit and push. There you go, 5 minutes flat !

Finally, screw the interior handle back on. If you have a bit of slack, you can also replace the outer handle (remember the screw in the battery cover?). Warning, if you add the length of the outer handle in addition to what can come out of the cylinder and the junction between the two, you have a not insignificant growth coming out of your door (about 7 cm). And if your lock is close to the outside stud, you may have a problem opening. Indeed, it may be that the handle of the connected lock come butter on the frame of your door and that you cannot open or close it… In this case, the outside handle being flattened on the top, you can try to save space by turning this face towards your jamb. But that may not be enough.

Use with the app

Now let's take a look at the app. As announced, the We.Lock system also works in Bluetooth. Okay, let's be frank, the app is bad. Especially the installation guide is completely next to the plate concerning the explanations.

Download the app, register with an email or a phone number. You will receive a verification code, to be entered just before your password. Once done, scan the QR-Code on the end of the handle. Until then, it's good. Enter the lock ID. Contrary to what the guide marks in bold, it is indeed the ID of the lock that you will find engraved under the barrel. So make a note of it before fitting your lock. Don't forget to activate Bluetooth and GPS (required with Android).

This done, your cylinder will appear on the application… in duplicate. There is an exterior and interior “view”. This will allow you, by clicking on it, to know if it is open or closed ... If the logo of your lock is blue, it is connected via Bluetooth. Unfortunately, you have a good chance of not being able to connect to it. You will get a message saying the lock is offline ... Close and relaunch the app and you should be fine. By the way, we didn't tell you the app was really bad ?

In spite of everything, let us be merciful with this application by the fact thatit will hardly be of use to you with this lock. The only use that you will be able to have is to come, with the function "Add", give access to a third-party user for a certain period. User who will also have the application. Other than that, since the lock will work with an RIFD chip or a papillary impression (and not papillae, because the diaper is less well recognized), you will have no other possibility to create temporary accesses.

If you really want it, you can come and open or close your lock via Bluetooth via the "unlock" entry. But hey, when we're in front of the lock, sweaty, are we going to pull out our phone and open the app, or just press to open? Hard dilemma! No, not really a difficult choice because we will systematically put our finger on it to open. It's easier. Didn't you tell you that the app was useless ?

Oh yes, it can help you in case of a problem. If you run out of battery, you can come and connect your smartphone or even a "Power Bank" via a USB plug hidden under the QR-code of the exterior handle. Thanks to this, you will activate the lock and you will be able to open it in Bluetooth via the application. So yes, I hear you! Gna gna gna, security… Gna gna gna, anyone can use this subterfuge… Well no ! Because remember, to open and close it, you have to enter the lock that you have made recognize by the application thanks to the ID which is noted on the barrel. So no, you and only you can use it.

As you can see, the application has virtually no interest, except to come and manage temporary access. The use with a Wi-Fi box can certainly add added value, especially as the use seems possible to the voice, but to be seen. We'll get back to you as soon as we get our hands on this Arlésienne.

Once the barrel is installed, the use and settings are very simple. To activate the lock, press the Power button for about 8 seconds. You will then have access to "System config". You will navigate between the different menus by pressing the same button. To validate, simply wait.

First, come and register administrator fingerprints. These latter will be able to activate and deactivate other administrators and "guests". To activate an administrator, select « Add Admin N ° 1 » and place your finger on the sensor. There are going to be three readings and that's it. One beep, one message « ID # 001 FP Added » appears and it is fixed. You can put three administrators. Be careful, on the other hand, if you do not enter an admin fingerprint, everyone will be able to open your lock.

To add a “guest” fingerprint, activate the lock, press  for 8 seconds to enter "System Config" and navigate until you see " Add: User FP ". When the message " AdminCheck "Appears, put your finger on the sensor (it is made to withstand up to 100.000 pressures) and once done, when the message" ID 004 Adding - Read FP 3 times Appears, ask the person concerned (unless you have their finger in your loved one) to come and scan their fingerprint. When " ID # 004 004 FD Added Appears, it's good. If you have other volunteers or fingers on hand, you can pass them one after the other (ID # 005, 006, 077… until 100 max).

The same goes for transponders or RFID cards. In "System Config", choose " Add IC card », Have your fingerprint recognized and scan the card by passing it over the top of the handle. The message " ID: 1 Added ". You have 10 seconds to pass the other 2 transponders provided if you wish.
And if you want to remove fingerprints or RFID cards, you just have to come and select the option in the " SystemConfig ". You can also reset the lock with the option " Restore to Init State ».

Once done, the opening is very simple:

  • Imprint: press the Power button and press the pad of your finger (the registered finger) on the sensor. And There you go.
  • Transponder: press the "Power" button and slide the RIFD card over the lock. And There you go.

It's very simple… and poorly thought out. Indeed, once your fingerprint or the card has been recognized, you will hear a BEEP. You can then turn the handle and your lock will open. If you turn it the other way quickly, it will close. If you wait a bit, the system becomes neutral again, i.e. the handle spins in a vacuum. This is also his basic condition. It therefore seems that this handle was designed for doors that can be closed "with a key" directly. You know, that of certain apartment doors in particular ... The problem is that this type of door is not the most common, especially in homes. But, no problem so far, if your lock is in the open position, do the same operation as to open it and turn the handle in the closing direction.

Another problem, if your fingers are wet or damaged, drop. In these cases, use the app or a transponder.

To conclude this test, The We.Lock SECB connected lock is a secure product, easy to install and use, with very good materials. It does not require any modification to your door, no installation of a box, and is set up in 5 minutes. But, like all locks of the brand, it is relatively cumbersome (be careful to be able to close your door) andthe application as well as the Bluetooth connection are a real challenge and useless, or almost. Although the fingerprint recognition is very good, however, we keep a preference for transponders, but hope to test the Wi-Fi module soon to see what it brings to this lock.
