SIRO Bluetooth smart door lock locking cylinder SL03512B

The SIRO Smart locking cylinder for the house door lock SL03512B can be used for a new door or for retrofitting an existing door lock. After simply inserting or replacing the lock cylinder, the SIRO Smart door lock offers you a wide range of options for locking and unlocking your front door: PIN code, fingerprint, chip card, smartphone and the emergency key.

Connected to your smartphone via Bluetooth, the Smart Lock also offers the option of remote control, access control and, if necessary, warning messages in the event of unauthorized access.

Smart door lock – never locked out again

Many of us know this scene: once you don’t pay attention, you leave the house without a key and the door slams – you’re at the mercy. Hours of waiting for the locksmith and a high bill of hundreds of euros are the result.

None of this will happen to you with the SIRO Smart lock. With a smart locking cylinder, it is practically impossible to lock yourself out.

Ideal for holiday homes, hotels, rental apartments, offices and practices

The use of the SIRO Smart Life lock is also particularly suitable in the commercial and business sector. The connection to the Smart Life app offers you many options: the re-coding of the PIN code when the user changes, providing access for staff from remote locations or denying access under certain conditions, for example different access rights depending on the employee.

In short, you can manage the access to all doors more easily and securely with the Smart Life app, at home and in offices.


Always on the safe side

It is always possible to open your door with a SIRO Smart lock. If the battery is empty, you can simply connect a power bank via USB for an emergency power supply. You can also get emergency access using the mechanical key provided.


Smart programming via the Smart Life app

Like any smart device, the SIRO Smart lock can also be integrated into all smart programs such as time switching or scene creation in your Smart Life app.
