6. Operating Instructions
This section explains how to use your ABUS folding lock, including its alarm function.
6.1 Locking Your Bicycle
- Remove the lock from its mounting bracket.
- Unfold the lock segments to their full length.
- Wrap the lock around your bicycle frame and an immovable object (e.g., a bike rack, lamppost). Ensure the lock passes through a wheel and the frame for maximum security.

- The alarm system will arm automatically after a few seconds, indicated by a short beep or LED flash.

6.2 Alarm Function
The integrated alarm is triggered by significant movement or impact. It typically provides a warning sound before a full alarm to allow for accidental bumps.
- Warning Sound: A short, less intense sound will activate upon initial minor movement. This allows you to adjust the bike or prevent accidental full alarms.
- Full Alarm: If movement continues or a stronger impact is detected, a loud, continuous alarm will sound for a set duration (e.g., 15-20 seconds) before re-arming.
- The alarm will reset and re-arm if no further movement is detected.
6.3 Unlocking Your Bicycle
- Insert the key into the lock cylinder.
- Turn the key to the unlocked position. This will disarm the alarm and release the locking mechanism.
- Remove the locking bar and fold the lock segments back into their compact form.
- Store the lock in its mounting bracket for transport.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your ABUS lock.
- Cleaning: Wipe the lock body and segments with a damp cloth to remove dirt and grime. Avoid harsh chemicals.
- Lubrication: Periodically apply a small amount of lock lubricant (e.g., graphite-based or silicone spray) to the keyhole and moving parts of the locking mechanism. This helps prevent sticking and ensures smooth operation.
- Battery Replacement: The alarm system requires one CR2 battery. When the battery is low, the lock may emit a specific warning sound or LED indicator. To replace the battery, locate the battery compartment (usually secured by a small screw), open it, replace the old battery with a new CR2 battery, and securely close the compartment. Ensure correct polarity.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm triggers too easily or falsely | High sensitivity; environmental vibrations; loose mounting. | Ensure the lock is mounted securely. Avoid parking in areas with heavy vibrations. Some models may have adjustable sensitivity (refer to specific product details if available). |
| Key sticks or is difficult to turn | Dirt or debris in the cylinder; lack of lubrication; worn key. | Apply lock lubricant to the keyhole. Clean the key. If the problem persists, contact support. |
