Aucurwen Bike Chain Lock offers two ways to unlock: by password and by keys. When you forget to bring the key, you can unlock it with the password. Compared with traditional bicycle locks, this feature provides more convenience as it can be unlocked without a key. The 4-digit passcode is also resettable, allowing you to set it to your desired code.

In contrast to other combination bike locks, Aucurwen's bike lock with key and combination has higher fault tolerance. If you forget the password you set, the traditional combination bike chain lock can no longer be used, but our bike lock with key and combination can still be unlocked with a key.

The plug of Aucurwen's bike chain lock is made of high-quality ABS material, which has high hardness and good toughness, making it not easy to break. The bike chain lock features a 0.24-inch thick heavy-duty alloy steel chain with high cutting resistance to prevent easy cutting and keep your bike safe.

The lock cylinder of the bike chain lock contains some high-precision zinc alloy parts, giving it both a smooth rolling feeling and cutting resistance. Additionally, the protective cloth sleeve not only protects the chain from rust but also prevents the chain from scratching the bicycle frame.

Aucurwen's bike chain lock combines shear, cut, and drill resistance, making it a formidable deterrent against thieves. With a length of 3.2 feet, it is enough to lock 2-3 bikes together. The convenience and high fault tolerance of this bike chain lock allow it to be unlocked with a 4-digit combination or with keys, making it easy to use and carry.

Moreover, the Aucurwen bike chain lock is not just for bikes; it can also be used to lock electric bikes, scooters, motorcycles, doors, grills, and more. You'll find many uses for this versatile bike lock.

To reset the password, simply turn the knob clockwise 90°, adjust to the password you want, and then turn the knob 90° counterclockwise. Remember the new code and use it to open the bike chain lock. With a 1-year warranty and friendly customer service, Aucurwen provides a worry-free experience for its customers.
