How to Reset a Four Digit Combination Bike Lock
- 1). Move the lock dials to the current combination or the factory preset combination. A new lock will come with the preset combination on a small piece of paper. Align all four dials along the red or black placement line, which is between each dial towards the center of the lock.
- 2). Pull the cable or shackle out of the lock housing.
- 3). Slide the reset lever upward until it doesn't move any farther. The reset lever is located at the end of the lock, past the number dials. It's a small piece of metal that moves above or below the hole that the shackle is housed in.
- 4). Turn the dials one at a time to the new combination. All four numbers should all be aligned with the red or black guide line.
- 5). Lower the reset lever until it doesn't go any farther. The combination has been reset.
- 6). Insert the cable or shackle into the lock housing. Since the current combination is still on the guide line, the lock will stay unlocked.
- 7). Change the combination numbers so they do not match the new combination. Press the cable or shackle inward and the lock will lock.
