How can I reset code if forgotten?
Answer: If you look on YouTube, there are a few videos in which people show you how to determine what a forgotten combination is (ie. Pick the lock). I’ve done it myself, it is not too hard, just takes some time. I suppose that the other option is to try all possible combinations. Start at 0000, then 0001.....0002..... and so on. Eventually you will stumble across you code. Might be easier to just order another lock. Good luck! -

Master Lock Combination Padlocks 643D Editorial Review
Master Lock Indoor Combination Padlock, 1-9/16-inch Wide, Silver 643D provides a customizable security option, allowing users to set their own combination. However, several users have experienced issues with the lock seizing up after limited use, leading to frustrating situations where access to personal belongings was hindered, especially in vulnerable moments like after showering. Although some users praised the lock's construct and ease of use, durability appears to be a concern. Clear instructions for setting combinations are provided, yet not all users seem to follow them correctly, which adds to the confusion about functionality. Thus, despite being a reputable brand, potential buyers might want to explore other options for reliability.
