Operating Instructions
Locking Your Bicycle
- Select a Secure Object: Choose a sturdy, immovable object to lock your bicycle to, such as a dedicated bike rack or a robust pole.
- Position the Lock: Place the shackle around your bicycle's frame (and ideally a wheel) and the chosen secure object. Ensure the shackle is positioned to minimize leverage points for potential thieves.
- Engage the Shackle: Insert the shackle ends fully into the lock body. Ensure a snug fit to prevent excessive movement.
- Turn the Key: Insert one of your coded keys into the lock cylinder and turn it to secure the shackle. Remove the key and store it safely.

Unlocking Your Bicycle
- Insert Key: Insert your coded key into the lock cylinder. The rubberized weather-resistant key seal protects the mechanism.
- Turn and Release: Turn the key to disengage the locking mechanism. You may need to apply slight pressure to the shackle to release any tension.
- Remove Shackle: Once unlocked, pull the shackle free from the lock body and the bicycle.

Maintenance
- Key Mechanism Care: Periodically clean the keyhole and internal locking mechanism to prevent debris buildup. Use a small amount of a suitable non-greasy lubricant (e.g., graphite-based or silicone spray) if the key feels stiff.
- Rubberized Coating: The lock features a rubberized coating to protect your bike frame. Inspect this coating regularly for any cuts or wear that could expose the metal core.
- Storage: Store the lock in a dry environment when not in use to prevent corrosion, especially if exposed to moisture.
Troubleshooting
Difficulty Turning Key
If you experience difficulty turning the key, ensure the shackle is fully inserted and properly aligned within the lock body. Sometimes, slight pressure on the shackle can help align the internal components. If the issue persists, apply a small amount of lubricant to the keyhole and key, then try again.
Lock Mechanism Stiffness
A stiff lock mechanism can often be resolved by applying a suitable lubricant directly into the keyhole and working the key in and out several times. This helps to clear any internal obstructions and ensures smooth operation.
