Key Features:
- Reinforced Pin and Lock Cylinder: The pin and lock cylinder are upgraded, made from sturdy zinc alloy, offering superior strength and rust resistance. The pin is die-cast in one piece for increased diameter and elasticity, significantly enhancing security.
- Upgraded Combination Wheel: Internal gears are made of galvanized alloy for smooth operation and rust prevention. The outer shell is high-strength ABS, providing impact resistance, wear resistance, and corrosion resistance, protecting internal components.
- Thick Alloy Steel Chain with Fabric Cover: The 7mm thick high-strength alloy steel chain is galvanized and rust-protected, making it difficult to cut. The polyamide fabric cover is heat-resistant, corrosion-resistant, and wear-resistant, protecting the chain and preventing scratches on your vehicle's frame.
- High Security 5-Digit Combination: Offers 100,000 unique combinations, significantly more secure than 4-digit locks. Keyless design eliminates concerns about lost keys.
- Wide Range of Applications: Versatile for securing bicycles, motorcycles, electric scooters, strollers, gates, ladders, lawnmowers, and more. Multiple locks can be linked for extended reach.
2. Setup: Setting Your Combination
Your ZELENY chain lock comes with a preset combination (usually 00000). Follow these steps to set your personal 5-digit combination:
- Open the Lock: Align the preset combination (e.g., 00000) with the indicator marks on the lock head and pull the pin out to open the lock.
- Rotate the Inner Knob: Inside the lock head, locate a small knob or lever. Rotate this knob 90 degrees clockwise (or as indicated by an arrow) until it clicks into place.
- Set Your New Combination: With the knob rotated, carefully turn each number dial to your desired 5-digit combination. Ensure the numbers are perfectly aligned with the indicator marks. Choose a memorable combination.
- Return the Inner Knob: Rotate the inner knob back 90 degrees counter-clockwise to its original position. This will lock in your new combination.
- Test Your Combination: Scramble the numbers on the dials. Then, enter your new combination and attempt to open the lock. If it opens, your new combination is set. If not, repeat the steps carefully.
Important: Make sure to remember your new combination or write it down in a secure place. There is no master key or reset button if you forget it.

4. Maintenance
Proper maintenance will extend the life and ensure the smooth operation of your ZELENY chain lock.
- Cleaning: Periodically wipe down the lock mechanism and chain with a damp cloth to remove dirt and grime. Avoid harsh chemicals that could damage the fabric cover or plastic components.
- Lubrication: If the combination dials become stiff or the pin is difficult to insert/remove, apply a small amount of silicone-based lubricant or graphite powder to the moving parts of the lock mechanism. Do not use oil-based lubricants as they can attract dirt.
- Fabric Cover Care: The nylon fabric cover is designed to be durable. If it gets wet, allow it to air dry completely before storing the lock to prevent mildew.
- Storage: Store the lock in a dry place when not in use to prevent rust and corrosion, especially if exposed to moisture.
