Its design includes an adjustable cylinder that fits doors with a thickness of between 55 and 115 mm, and features a motorized system that facilitates opening even on armored doors.

Who it’s for and who it’s not for. It’s designed for the door of a rental property or a second home where different people enter: it opens with a mobile phone and guests are managed through the app. It is not an access control system for a business with many users and schedules, nor does it replace an alarm: it simply opens and closes, without notifications.
What’s included in the box. The motorized lock with its extendable European profile cylinder and long lever, and the 3 CR123 batteries, which are included and last about 6 months with an average of 10 openings per day. It measures 60 x 60 x 145 mm and weighs 600 g.
How we install it on the Costa del Sol. The door cylinder is replaced without any construction work: the body is adjustable for doors between 55 and 115 mm thick, and its motor opens even on armored doors. Then, the Cloud Smart Lock app is installed on iOS or Android, and users are registered. In an apartment on the Costa del Sol, this prevents the need to duplicate keys each season.
Frequently Asked Questions
Will it fit my door?
If the cylinder is of European profile, usually yes: the body is extendable and adapts to doors 55 to 115 mm thick, with a long lever. What you should check beforehand is the thickness of the door leaf and the type of cylinder currently installed.
Can it be opened while outside the city?
Not really: the connection is Bluetooth 4.0, so it can only be opened with the mobile phone when at the door. To control it remotely, you need to add the Safire WiFi connection module, which is a separate product.
Can I grant access to someone for just a few days?
Yes, the app allows you to manage guest users remotely. This is what differentiates it from a key copy: permissions can be granted and revoked without changing the cylinder.
