- Insert the Shackle: Align the ends of the U-shaped shackle with the openings in the crossbar (the straight part of the lock).
- Push to Lock: Push the shackle firmly into the crossbar until it clicks into place. The lock is now engaged.

- Turn Key: Turn the key to the unlocked position.
- Remove Shackle: Pull the U-shaped shackle out of the crossbar.
- Remove Lock: Detach the U-lock from your bicycle and the secure object.

6. Maintenance
Regular maintenance will help prolong the life and functionality of your M-Wave U-Lock:
- Lubrication: Periodically apply a small amount of graphite-based lubricant or a specialized lock lubricant into the keyway and the shackle mechanism. This helps prevent corrosion and ensures smooth operation. Avoid oil-based lubricants as they can attract dirt.
- Cleaning: Wipe down the lock with a damp cloth to remove dirt and grime. Ensure the lock is dry before storage.
- Key Care: Do not force the key if it feels stiff. Apply lubricant and try again. Avoid using damaged or bent keys.
7. Troubleshooting
If you encounter issues with your M-Wave U-Lock, consider the following:
- Key is Stiff or Won't Turn: The lock mechanism might be dirty or dry. Apply lock lubricant to the keyway and try again. Ensure you are using the correct key.
- Shackle is Stuck: Check for any obstructions in the shackle openings or within the crossbar. Lubricate the mechanism as described in the maintenance section.
- Lock is Frozen: In cold weather, moisture inside the lock can freeze. Use a de-icing spray or warm the lock gently (e.g., with warm water, then dry thoroughly) to thaw it.
