Direct from the United States, this Yale signed lock has as its main promise to be compatible with 95% of the locks on the market. An ambitious goal given the great diversity of France at this point.

Observation 1: It’s imposing (15cm tall and 5.8cm wide), but it manages to stay relatively sleek thanks to its clean lines. We will have to choose between a silver gray and a slate black. Installation is simple since the existing barrel will be reused. If the latter is not compatible, it is always possible to buy one as an option. Another possible addition: that of a keyboard if you prefer to use a code.

The rest of the time, control is done via the Yale Access app, which allows remote opening if you invest in the Yale Connect Wifi bridge. The latter also opens up practical temporary access rights management functions for seasonal rentals. Power is supplied by 4 AA batteries.

A good lock easy to install and use, shame it’s so bulky. You can find the Linus Smart Lock test here.

Nuki Smart Lock 3.0 Pro: for its complete ecosystem

The Nuki Smart Lock 2.0 was one of our reference models and this version 3.0 confirms this impression. The design does not really evolve, we are left in the presence of an imposing device that really will not go unnoticed. However, we do appreciate the arrival of a white version that could potentially be more understated.

Once optional, the USB-C rechargeable battery is now standard. It is more practical on a day-to-day basis, but also a bit more imposing, the latter forming quite a visible growth.

Its installation is simple since it reuses the cylinder and the existing key. Alone, its functions are very classic, with opening from the smartphone in Bluetooth, but now also in Wifi. So no need to add the jumper to control your lock from anywhere! An option that affects stamina, however, now worse than version 2.0.

The ecosystem of accessories remains the same as always, so we can add an opening detector, a remote control in key ring format, but also a connected digital code, the Keypad 2.0, which we were able to test. The latter, reliable and efficient in all situations, adds the possibility of opening the door with your fingerprint. Therefore, it is particularly practical for people who do not have smartphones, such as children.

It is also full of integration of voice assistants since we find Alexa, HomeKit and Google Assistant. A model that we would have liked more discreet, but that will interest those who seek versatility. We were able to test the latter infrandroid.

Note that there is a non-Pro model, ignore battery and WiFi, but it’s only €170.

Igloohome Smart Deadbolt, ideal for vacation rentals

This is the best lock available for rent, especially on AirBnB. It incorporates a practical digital code system, but you can also open the door with your smartphone or a physical key.

Another advantage is that the lock can work without Wi-Fi, which is very useful in areas where the Internet connection is random or non-existent. You also have access to a control panel online or through the dedicated app. Specifically, you can remotely generate access PIN codes for a limited time: for a few hours, a day, a week, a month… perfect for rentals. You can also sync the lock directly with your AirBnB booking calendar.

Note that an alarm is also built in and sounds in the event of an attempted break-in.

Everything you need to know about smart locks

Are smart locks compatible with all doors?

The models available in our regions adopt the European profile and are therefore compatible with the vast majority of doors. Most of the time, simply swapping out the existing cylinder and swapping it out with the supplied one will suffice. Therefore some high security locks will not be supported.

How am I going to open my door?

Depends ! Most padlocks on the market use an app and your phone’s Bluetooth. Some models offer digital codes, cards or even fingerprint readers. Finally, all locks offer a physical emergency key.

Is it possible to open the door remotely?

Some locks can be opened remotely from anywhere in the world. The most common solution requires going through a bridge that will communicate between the lock and the Internet.

Do you have to recharge your padlock?

Who says electronics says power and therefore your lock needs power. Therefore, the vast majority of models use AA or AAA size batteries. The autonomy varies according to the model and the frequency of use and generally ranges from 3 months to a year. Therefore, we recommend that you invest in some rechargeable batteries to limit costs (and waste) over time.

What happens in the event of a power or internet outage?

Don’t worry in the event of a massive internet or power outage, most of the connected locks can operate locally and are also equipped with their own battery or battery. However, some remote control functions may not be available. And in the worst case, it is always possible to use a conventional key in an emergency. Be careful though, this requires access to said key, so it’s a good idea to give a copy to a loved one.

Are smart locks really secure?

If you are looking for a 100% inviolable lock, go your way. Forcing a door open is only a matter of time for a motivated intruder, and mechanically these locks are identical to their conventional cousins.

Their connected side even opens additional attack paths, the locks themselves suffer from potential vulnerabilities. Security researchers regularly make them public… So buy a connected lock for its convenience, not its security.
