Frequently Asked Questions

How loud is the alarm?

The alarm produces 100dB of sound when 3D motion is detected — loud enough to deter tampering and alert the owner.

What batteries does it use?

Two AAA batteries power the alarm and LED indicators. ABUS includes a set with the lock.

Can I replace my keys if I lose them?

Yes. The X+ key cylinder is user-replaceable, and you can order new keys from ABUS using your lock serial number.

Will the alarm go off if my bike is bumped by traffic?

The 3D motion sensor is calibrated to trigger on significant vibration or movement — minor bumps typically won't activate it, but sensitivity depends on mounting and bike position.

Is this chain proof against bolt cutters?

The 12mm hardened steel chain resists standard bolt cutters. Combined with the Level 18 disc lock, it provides dual security against most common theft methods.
