2. Setting Your Personal Code
Your AXA Absolute C5 lock comes with a factory preset code, usually "0000". It is highly recommended to change this to a personal, memorable four-digit code immediately after purchase.
- Open the Lock: Align the dials to the current opening code (factory default is "0000") and press the release button to open the lock.
- Locate the Reset Mechanism: With the lock open, look for a small reset button or screw on the side or bottom of the lock mechanism. This is often a small, recessed button that requires a pen tip or a small screwdriver to press.
- Enter Reset Mode: Press and hold the reset button/screw. While holding it, rotate the dials to your desired new four-digit code. Ensure the numbers are clearly aligned with the indicator marks.
- Confirm New Code: Release the reset button/screw. Your new code is now set.
- Test the Code: Scramble the dials and then re-enter your new code to ensure it opens the lock correctly. If it does not open, repeat the steps carefully.

Important: Remember your new code. There is no master key or backdoor to reset the code if forgotten without knowing the current code.
3. Operating Instructions
3.1. Locking Your Bicycle/Scooter
- Position the Vehicle: Park your bicycle or scooter in a secure location, ideally near a fixed object like a bike rack, lamppost, or sturdy fence.
- Wrap the Chain: Loop the chain around the frame of your bicycle/scooter and the fixed object. Ensure the chain passes through a non-removable part of your vehicle, such as the frame, and not just the wheel.
- Insert the Pin: Insert the locking pin into the lock body. The automatic click-in function will secure it.
- Scramble the Dials: Once locked, scramble the code dials to prevent unauthorized access.

- Press Release Button: Press the release button on the lock body. The locking pin will spring open.
- Remove the Lock: Detach the chain from your bicycle/scooter and the fixed object.

4. Maintenance
Proper maintenance will extend the lifespan of your AXA Absolute C5 lock and ensure smooth operation.
- Cleaning: Wipe the lock body and chain cover with a damp cloth to remove dirt and grime. Avoid harsh chemicals.
- Lubrication: Periodically apply a small amount of silicone-based lubricant or lock lubricant to the moving parts of the code mechanism and the locking pin. This helps prevent sticking and corrosion, especially after exposure to rain or dust.
- Storage: When not in use, store the lock in a dry place to prevent rust and maintain the integrity of the polyester cover.
- Polyester Cover: The black polyester cover is designed to protect your bike's paintwork. Inspect it regularly for tears or excessive wear.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Dials are stiff or hard to turn. | Dirt, dust, or lack of lubrication. | Clean the dials and apply a silicone-based lubricant to the mechanism. Work the dials back and forth to distribute the lubricant. |
| Locking pin does not click in or release smoothly. | Debris in the locking mechanism, lack of lubrication, or misalignment. | Ensure the pin is inserted straight. Clean any visible debris. Apply lubricant to the pin and inside the locking hole. |
| Cannot open the lock with the correct code. | Dials not perfectly aligned, code forgotten, or internal mechanism issue. | Double-check that each number is precisely aligned. Try slightly adjusting each dial. If the code is forgotten, the lock cannot be opened without knowing the code. |
| Polyester cover is damaged. | Wear and tear, sharp objects. | While minor damage may not affect security, significant tears could expose the chain and potentially scratch your bike. Consider replacing the lock if the cover is severely compromised. |
