FAQ

Can the CYLOX One be fitted to any door?
The CYLOX One smart door cylinder replaces the existing door cylinder. You can adapt its length to the thickness of your door using the appropriate extension pieces (included in the scope of delivery). The forend screw supplied is suitable for mortise locks with a backset of up to 71 mm.

How easy is it to install the CYLOX One?
To install the CYLOX One, the existing profile cylinder is removed. To do this, open the door to loosen the forend screw and pull it out. The locking cylinder is then removed. Now you can insert the CYLOX One and fix it in place with the faceplate screw. It is best to follow the step-by-step installation instructions included in the sales packaging.

How long does it take to install the CYLOX One?
Installing and configuring the CYLOX One is straightforward and can be done in just a few minutes. Especially if you have already familiarised yourself with the operating instructions before installation.

How do I connect the CYLOX One to the ABUS One app?
To link the CYLOX One with the ABUS One app, you need the keycard supplied. This serves as proof of identification that you are the owner of the smart electronic cylinder. The connection process is started by scanning the keycard with your smartphone. All further steps are then explained and carried out in the ABUS One app.

How is the CYLOX One operated?
If you want to lock or unlock your door, activate the CYLOX One using the free ABUS One app on your smartphone or smartwatch.

Alternatively, you can also activate the smart door cylinder using the separately available remote control, finger scanner or keypad.

Is the CYLOX One compatible with smart home systems?
Yes, the CYLOX One can be integrated into standard smart home systems using the optionally available BRIDGE One.

Can I also control the CYLOX One while travelling?
With the separately available BRIDGE One, you have the option of activating the CYLOX One on the move or granting access authorisations - even outside the Bluetooth® wireless range.

Is the CYLOX One weatherproof and suitable for outdoor use?
Yes, the CYLOX One is certified to protection class IP67 and is therefore dust and waterproof. The smart door cylinder can therefore be used in both outdoor and indoor areas where the temperature does not fall below -25 °C or exceed 65 °C.

How many people can have individual access rights to the CYLOX One at the same time?
You can grant individual access rights to up to 28 different people.

How do I change the battery of the CYLOX One?
To change the battery, you will need the opening key included in the packaging. To open, the opening key must be hooked onto the outer knob and turned anti-clockwise.

Remove the loosened outer knob and replace the battery underneath. Then replace the outer knob (please ensure that the dot marking on the outer knob and the centre of the bar on the cylinder are aligned) and tighten with the opening key.

How do I clean the CYLOX One?
It is sufficient to clean the CYLOX One with a damp cloth if necessary. Aggressive cleaning agents should not be used.

At least twice a year, you should treat the inside of the door cylinder with care products (do not use resinous oil, graphite spray or graphite powder). We recommend the ABUS care spray PS22.

How is the CYLOX One supplied with power?
The CYLOX One is powered by a replaceable CR2 battery. One battery is included in the scope of delivery.

How long does the CYLOX One battery last?
How many openings and closings the CYLOX One can perform with one charge of batteries before they need to be changed depends on many factors.

As a rough estimate: With normal frequency by a family of four, it can be assumed that the battery will need to be replaced after around 1.5 years.

Tip: The battery status is displayed in the app.

How is the CYLOX One protected against tampering and break-in attempts?
The CYLOX One uses Bluetooth® with AES 128-bit encryption for communication and is additionally secured by the tried-and-tested SmartX™ security protocol developed by ABUS.

The use of a finger scanner or keypad also offers reliable protection, as the accessory uses the same Bluetooth® security protocol as the CYLOX One and only reacts to registered fingerprints or stored codes.

The smart electronic cylinder offers SKG***-certified drilling protection thanks to hardened pins and a drilling protection bridge. The individual keycard is used to identify the cylinder as the sole owner.
