Master Lock 6-Foot Keyed-Alike Bicycle Cable Locks with Keys, Blue, Green, and Red 3-Pack (Model 8127TRI)

Product Overview

The Master Lock 6-Foot Keyed-Alike Bicycle Cable Locks are a set of three locks designed for securing bicycles. The set includes blue, green, and red cables, each featuring a keyed cylinder and a matching key. All locks share the same key, simplifying access when multiple locks are in use.

Key Features

• 6‑foot cable length for connecting a bike frame to a fixed object.
• Keyed‑alike cylinders allow one key to open all three locks.
• Three color options provide visual identification.
• Includes keys that match the cylinder.
• Model 8127TRI.

Design and Construction

Each lock is composed of a flexible cable and a metal cylinder. The cable’s length allows a user to wrap it around the bicycle frame, a stand, or another immovable object, then insert the cylinder into the lock housing. The cylinder is accessed by turning the key, which releases the locking mechanism to allow removal or replacement of the cable.

The colored cables are intended to make it easy to identify different locks within a set. This feature is useful when a cyclist wishes to secure more than one bicycle at a time or when multiple locks are attached to a single frame for added convenience.

Keyed‑Alike Functionality

All three cylinders are keyed alike, meaning the same key can be used for any of the locks in the set. This shared key system eliminates the need to carry multiple keys and reduces the risk of losing a key if only one set of keys is carried. The key is designed to fit the cylinder securely and to operate the lock’s mechanism.

Usage Scenario

When a cyclist arrives at a parking spot, the 6‑foot cable can be looped around a sturdy pole or bike rack and the cylinder can be positioned against the lock housing. The key is inserted into the cylinder, turned to lock the cable, and the bike is secured. The lock remains attached to the cable, allowing the user to detach the bike by unlocking the cable with the same key.

Because the locks are keyed alike, a cyclist can use any single key to open all locks in the set, regardless of which color is attached to a particular bicycle. This is especially useful when traveling with multiple bicycles or when several locks are needed for one bike, such as securing the frame, seat, and handlebar to a fixed object.

Maintenance and Care

To maintain the lock’s functionality, periodically check the key and cylinder for smooth operation. If the key no longer turns easily, clean the key’s threads with a dry cloth and ensure no debris has entered the cylinder. The cable can be inspected for kinks or damage after prolonged use. Replacing a damaged cable is possible if the user has a spare of the same model and length.

Storage Tips

When not in use, store the locks in a dry area to avoid moisture accumulation. Keeping the lock housings and keys dry helps maintain the integrity of the cylinder mechanism. A small container or a dedicated lockbox can keep the set organized and prevent loss of individual components.

Package Contents

The 3‑pack includes:

• Three 6‑foot bicycle cable locks (Blue, Green, Red).
• Three keys that match the cylinders.
• Packaging that protects each lock during shipping.
