Unlocking the Code: How to Reset a 3-Digit Combination Lock


Combination locks are a popular security solution for many homeowners as they offer convenience and are relatively inexpensive. However, it can be frustrating when you forget your combination or need to reset your lock after sharing access with someone else. In this guide, we’ll discuss how to reset a 3-digit combination lock step-by-step.

Understanding 3-Digit Combination Locks

Before we dive into resetting the lock, it’s essential to understand how a 3-digit combination lock works. It consists of three dials, each featuring digits from zero through nine. The user sets their unique three-digit code by aligning the numbers on each dial according to their chosen sequence.

Once set, the only way to open the lock is by entering that specific combination of numbers in sequence. Forgetting your assigned code happens more often than most people would like.

Step-by-Step Guide: How to Reset Your 3-Digit Combination Lock

Follow these simple steps below if you want to reset your combo:

Step #1 – Open Your Lock

Use your existing combination code (if you remember it) or use bolt cutters if you’ve completely forgotten about it or lost any paperwork that might hold that information.

Step #2 – Locate the Reset Button

The location of this button may vary depending on which kind of model you have; however, look for a small hole positioned right next where your current code usually goes.
In some models such as Masterlock-174D choose an outermost groove around where its current dial setting is located and position its shackle at that point.
Other manufacturers will have different procedures for finding their reset buttons and opening them so make sure double-check before proceeding further under “Documentation”.

Step #3 – Insert Something into the Hole

Next up select whichever pick tool/ paperclip / tiny screwdriver, that same one you usually use for unlocking a phone or opening up computers.
Insert the tool deep into the hole to reach and press the button below it.

Step #4 – Press and Hold

Once inside, press and hold the reset button until you hear an audible click. This confirms that your lock has been reset successfully.

Step #5 – Set Your New Combination

While holding down the Reset button modify each dial of your 3-digit combination with whatever new numbers you want them to have (make sure not to forget these!).

Pro tip: Choose something easy so you don’t risk forgetting this code again!

Step #6 – Test Your Lock

After setting your new combination on all three dials, turn all of them away from what they’re currently displaying.
Next step spin those dials back around; you should now see the digits as specified when setting it up earlier. Finally try pulling out its shackle once more and confirm whether everything is working well before locking anything else too much!


In conclusion, resetting a 3-digit combination lock is a straightforward process that requires just a few simple steps. By following our guide above on how to reset your combo, you can ensure that only authorized persons have access to your secured possessions while still experiencing seamless entry anytime!
