Q: Can I get a copy of instructions on how to reset lock code?

submitted by Jay W - 7 months ago
  • A: To set or reset the combination on your Master Lock 643D lock: Open your lock by entering the lock combination. The factory-set combination is 0-0-0-0. Turn the shackle 90° so that the notch on the shackle is aligned with the notch on the lock body. Press and hold the shackle down. While holding the shackle, set the dials to your new combination. Be sure that the middle of the numbers are lined up with the red stripe. Lift and return the shackle to the closed position. Scramble the dials. The lock now has a new combination. Be sure to record your combination in a safe place.

    This lock is a joke

    Bought 2 of these and immediately regretted it. Took about 6 more weeks before the tumbler broke on one and had to be cut off. Save yourself some money and go with the cheaper tried and true rotary lock instead.

    after only 3 months of having this lock the code switched on me and now i have to clip the lock to open it. this switches codes way to easily for it to be used as an everyday lock let alone a lock on its own. it’s a hard lock on its own which makes it annoying to clip open if you have locked yourself out. i don’t recommend this lock at all.

    Changed combination spontaneously

    Do not buy this lock. I locked it and suddenly couldn’t get it open. Called master lock customer service and all they had to say was “sorry sometimes this lock tends to shift numbers. Try different combinations close to yours and see if it unlocks or we could send you a replacement.” I thankfully jiggled it loose to open it but your lock shouldn’t just “shift” from your secure combination.

    DO NOT BUY

    I used the lock once for my gym locker. The second day I went it would not open. I had to have them cut the lock at the gym for me to retrieve my belongings. Do not waste your money. I spent around 15 mins trying to reset/unlock it. 15mins with a lock is not 1 or 2 or 3 tries I was there quite a bit of time until I had to surrender and have them cut it.

    Horrible lock! Do not purchase

    Do not buy this lock! The combination randomly stopped working, and I had to have a team member at the gym use bolt cutters to cut the lock off the locker. Such a waste of money.

    Easy to use

    Bought this for my middle schooler to use on PE school locker. Easy to use. But the loop doesn’t click into the hole that deep so it’s easy to think it’s locked in but it’s not. Just have to be very mindful to click it in and move the numbers around to ensure it’s locked.

    You HAVE to read the instructions. I know it seems strange for such a simple thing. But it’s not your ordinary locking situation given that you can change the combination as much as you want. Read the instructions and all will be well.

    DO NOT BUY! HAD TO BE CUT OFF!

    BUYER BEWARE!!! Several months after I started using this lock the combination suddenly changed on its own by one number. Fortunately it was a small enough change I was able to figure it out and continue using it. However today it stopped working all together and would not open with any combination…which occurred while it was locked on my locker at the gym meaning my clothes, keys, and phone were all locked up and inaccessible thanks to this malfunctioning lock!!! Fortunately the gym had a bolt cutter and was able to cut it off to help me retrieve my belongings. DO NOT BUY!!!

    This lock looks nice, however it’s way too easy to change the pin that when you lock it, you can accidentally change your combination without realizing. Twice I have had done this, once at the gym and needed to bolt cut it.

    I brought this lock, it worked fine for two weeks. The third week it would not open and had to use bolt cutters to open it. Mind you I was at the gym and couldn’t get my stuff out. Thank the Lord they owned some. A waste of money.

    This lock should be recalled.

    This lock is incredibly loose which I think causes it to inadvertently reset the code. This created an incredibly inconvenient situation which required it to be cut off. This faulty lock should be recalled.

    Terrible lock! It locks me out at times. It’s so inconvenient especially when you are trusting it to lock your belongings up. Sometimes it works and it’s not the code you set. Trash.
