About this part

A replacement key for the battery lock and steering lock. It is cut to your bike's code, so we need that code with the order.

Find it stamped on the steering lock at the front of the bike, or on the battery lock. Enter it in the order notes at checkout. Two versions exist and they do not cross over - a code that reads K325 is the older non-folding key, and one that reads K-007 is the newer folding key.
