Product Information

Full details

The ONGUARD K-9 Link Plate Combination Lock in Black is designed for cyclists seeking a balance between the security of a U-lock and the flexibility of a cable lock. Its primary benefit is its compact, foldable design that offers significant security through hardened steel plates and a pick, pull, and drill-proof cylinder, while still being versatile enough to secure frames and wheels. A potential consideration is its folded size, which, while compact, may require specific storage on the bike.

FAQs

How do I reset the combination on my ONGUARD K-9 lock?

To reset your combination, first unlock the lock using the current code. Then, locate the reset mechanism (often a small button or lever near the dials). While holding it in place, set your new desired combination. Release the mechanism to set the new code. Always refer to the specific instructions included with your lock, as methods can vary slightly.

What is the length of the ONGUARD K-9 lock when unfolded?

The ONGUARD K-9 Link Plate Combination Lock unfolds to a length of 88.5cm (approximately 35 inches).

Can this lock secure both my frame and wheels?

Yes, when unfolded to its full 88.5cm length, it is typically long enough to secure your bicycle frame and at least one wheel to a standard bike rack or post.

Is the Z-Cylinder truly pick and drill proof?

The Z-Cylinder is designed to be pick, pull, and drill resistant, offering a high level of security against common theft methods. However, no lock is completely impenetrable. It provides a strong deterrent for everyday use.

How does the mounting bracket work?

The included mounting bracket attaches to most bicycle tubes using adjustable straps. It allows you to conveniently carry the folded lock on your bike frame, ensuring it's readily available when you need it.

What is the best way to maintain this lock?

Keep the lock clean and dry. Periodically apply a dry lubricant to the combination mechanism to ensure smooth operation, especially after exposure to moisture. Avoid using oil-based lubricants that can attract dirt.

What material is the lock made from?

The lock is constructed from hardened steel plates, providing a strong defense against cutting tools.

Troubleshooting

Combination is difficult to turn or won't set.

Ensure the numbers are aligned perfectly with the indicator line. Try pressing down slightly on the lock mechanism while turning the dials. If changing the combination, make sure you follow the specific sequence of steps outlined in the manual for your model.

Lock feels stiff or jams.

The mechanism may need lubrication. Use a dry lubricant designed for locks and apply it sparingly to the dial and cylinder area. Work the dials back and forth to distribute the lubricant. Avoid using oil-based lubricants, as they can attract dirt.

Mounting bracket strap is loose or won't stay attached.

Check if the straps are correctly threaded and tightened. Ensure the bracket is positioned on a relatively smooth section of the bike tube. If the straps are worn, consider replacing them with durable, reusable zip ties for a more secure fit.

Lock does not fully open or close.

Check for debris lodged in the mechanism. Align the numbers precisely. If the issue persists after lubrication, there might be internal damage, and replacement may be necessary.

Pros and Cons

Pros

  • Offers a strong defense against common theft methods with hardened steel and a secure cylinder.
  • Flexible enough to secure both the frame and at least one wheel to a stationary object.
  • Its compact, folded form factor is convenient for transport when not in use.
  • Keyless operation via combination provides quick and easy locking/unlocking.
  • Comes with a practical mounting bracket for on-bike storage.

Cons

  • May not provide the same level of security as a dedicated, heavy-duty U-lock in high-risk areas.
  • The folding mechanism, while convenient, could potentially be a point of failure over time with heavy use.
  • The link plate design can be more susceptible to prying attacks compared to a solid U-lock.
  • Requires careful locking strategy to ensure both frame and wheel are secured effectively due to its length.
  • Combination locks can sometimes be less robust than high-security keyed locks.

Setup, Compatibility & Care

Setup:

  1. Set Combination: Initially, the lock will likely be set to a default combination (often 0000). Consult the product manual for specific instructions on how to change this to your desired 4-digit code. Typically, this involves turning a small dial or lever while setting the numbers.
  2. Mounting Bracket: Use the included bracket to attach the lock to your bicycle frame. Most brackets use hook-and-loop straps or clamps that can be adjusted to fit various tube diameters. Position it for easy access without interfering with pedaling or steering.

Compatibility:

  • Mounting: The bracket is designed to fit most standard bicycle frame tubes.
  • Locking: The 88.5cm length is suitable for securing frames and at least one wheel to most common bike racks, poles, and other stationary objects.

Care:

  • Cleaning: Wipe the lock with a dry or slightly damp cloth to remove dust and dirt. Avoid using abrasive cleaners or solvents.
  • Lubrication: Periodically, especially after exposure to rain or moisture, apply a dry lubricant (like graphite powder or a silicone-based spray) to the combination mechanism to ensure smooth operation.
  • Storage: When not in use, ensure the lock is stored in its folded position. If mounted on the bike, keep it clean and dry.
