The Property Card: keep it in a safe place

Please keep the Property Card in a safe place. Each Smart Door Lock is uniquely protected. If you lose the Property Card, no one, not even Netatmo, will be able to access the Smart Door Lock's settings.

Installation guide for the Smart Door Lock and Keys


Is the Smart Door Lock compatible with my front door?

The Netatmo Smart Door Lock is compatible with doors that are equipped with a euro cylinder. It can be installed on most doors with a maximum thickness of 10 cm (installation of an extension kit may be required, sold separately). It is compatible with doors fitted with both monopoint and multipoint locks. Doors fitted with lift-up handles are also compatible.

Check if your door is compatible:

What should I do if the batteries run out?

The Smart Door Lock is equipped with 4x AAA batteries that last over one year, which is much longer than most smart door locks on the market today. This ensures a stress-free everyday life. It’s forward-thinking, alerting you on your smartphone when the battery is low. And even if the battery is dead, you will still have access to a back-up micro USB port to reactivate your Door Lock using a power source such as an external battery or laptop.

Will the Smart Door Lock affect my house insurance?

Insurance companies generally offer cover against burglary, provided that the residents of the home take all the necessary steps to minimise the risk of break-ins.
Each insurance company may also have its own criteria for which security equipment the policyholder must install, ranging from the type of door and locks used, to the installation of an alarm system or surveillance cameras.

Rather than a complete lock mechanism, the Netatmo Smart Door Lock is an electronic cylinder made from high-strength stainless steel that fits into an existing door lock. This cylinder, designed by Netatmo, meets the strictest requirements in terms of physical and electronic security and burglary resistance, in accordance with European standard EN15684.
The cylinder is reinforced with an anti-drilling plate and 3 safety pins, making it highly resilient against physical attacks such as drilling, cutting, pulling and forced entry. Its design also makes it impossible to pick.

However, the determining factor for house insurance is typically related to your door’s level of resistance and its locking mechanism (security door, single or multipoint lock: 3 points, 5 points, etc.)
Insurance companies often require, as a minimum, a three-point lock. In certain areas with high burglary rates, the number of lock points required may increase.

The level of protection required by insurers to secure a home depends on a number of factors, such as the type of insurance policy taken out, the value of the furniture and other items to be covered, and the vulnerability of the home to theft.
These requirements will be outlined either in the general conditions of the section of the policy relating to theft coverage, or in the exclusions of the insurance policy. If in doubt, please contact your insurance company to review your cover in detail.

How do you install the Smart Door Lock?

Installing the Smart Door Lock is really easy. Just replace the existing door cylinder (or barrel) by following the instructions in the user guide provided.
Once the Smart Door Lock is installed, download the Home + Security app to complete the installation. The 3 Keys provided with the Door Lock can then lock and unlock your Door Lock. You can buy extra Keys and add up to 300 to your Door Lock. When you receive them, all you have to do is activate them on the Home + Security app.

Can I install the Smart Door Lock outside?

The Smart Door Lock is designed for interior use only. Its indoor handle shouldn’t be exposed to bad weather, so installing it on an outside gate is not recommended.

How can I add new Smart Keys to my Door Lock?

Need a spare key? Don’t worry about the locksmith! Now, you can simply order extra Smart Keys and follow the steps in the Home + Security app:
— Open the app and tap on “Add a new Smart Key”
