Setup
Attaching the Multi-Fixing Bracket
The SK110 lock includes a multi-fixing bracket for convenient storage on your bicycle. This bracket can be attached to various locations on your bike frame or seat post.
- Identify a suitable location on your bicycle frame or seat post that does not obstruct pedaling or other bike components.
- Use the provided straps or mounting hardware to securely fasten the multi-fixing bracket to the chosen location. Ensure the bracket is tight and stable.
- Once the bracket is installed, the coiled lock can be clipped into it for transport.

Operating the Lock
Locking Your Bicycle
- Remove the coiled cable lock from its multi-fixing bracket.
- Uncoil the cable and pass it through the frame of your bicycle and around a secure, immovable object (e.g., a bike rack, lamppost, or fence).
- Insert the free end of the cable into the locking mechanism until it clicks securely into place.
- Ensure the lock is fully engaged by gently pulling on the cable.
Unlocking Your Bicycle
- Insert one of the provided keys into the keyhole of the lock.
- Turn the key to disengage the locking mechanism.
- Remove the cable end from the lock.
- Coil the cable back and reattach the lock to its multi-fixing bracket for transport.
Three spare keys are included with your TRELOCK SK110 lock. Keep them in a safe place, separate from each other.

Maintenance
- Cleaning: Periodically wipe the cable and locking mechanism with a damp cloth to remove dirt and grime. Avoid harsh chemicals.
- Lubrication: Apply a small amount of lock lubricant (e.g., graphite powder or silicone spray) into the keyhole and locking mechanism every few months, or if the key becomes difficult to turn.
- Storage: When not in use, store the lock in a dry environment to prevent corrosion.
Troubleshooting
- Key is stiff or difficult to turn: Apply lock lubricant to the keyhole and insert the key several times to distribute the lubricant. Ensure the key is fully inserted before turning.
- Lock mechanism does not engage/disengage: Check for any obstructions in the locking mechanism. Ensure the cable end is fully inserted when locking. If lubrication does not help, the mechanism may be damaged.
- Cable appears damaged: If the cable shows signs of significant wear, fraying, or damage, the security of the lock may be compromised. Consider replacing the lock.
