How do you Reset a 4 Digit Combination Lock if you Forgot the Code?

Combination locks are widely used to secure belongings such as lockers, luggage, and safes. These locks require a unique four-digit code to unlock the lock. However, if you forget the code, it can be challenging to open the lock. Thankfully, there are ways to recover and reset the combination code. Here, we will learn how to reset a four-digit combination lock if the code is forgotten.

Understand how the Combination Lock Works

Before we get into the process of resetting the combination lock, let's get an understanding of how it works. A combination lock has a dial with numbers on it, and a shackle that connects the locking mechanism. The lock is locked when the shackle is in the down position and unlocked when the shackle is up. To unlock the lock, the user needs to input the four-digit code, turning the dial clockwise until all four digits are aligned with the arrow mark. Then, the user needs to pull the shackle up to open the lock.

Ways to Reset a 4 Digit Combination Lock

There are primarily two ways to reset a 4 digit combination lock when you forget the code. The first is to brute force the lock, and the second is to contact the manufacturer or locksmith. Brute forcing requires time and effort, while contacting the manufacturer or locksmith may require additional cost. Let's dive into the details of each one of these methods.

Method 1: Brute Force the Combination Lock

The brute force method involves trying all possible combinations until the lock opens. However, it's important to note that this method can take an enormous amount of time and may not succeed if the lock has a reset mechanism that locks the dial if the wrong code is used consecutively. This method is not ideal, but it's worth a try before opting to other methods.

Here is the step-by-step guide to resetting the lock through brute force:

1. Identify the starting and ending points on the dial – Not all combination locks have this feature, but some models have points where the dial can only stop at certain points. Identify the starting and ending points of the dial to narrow down the number of possible combinations.

2. Begin the digit-by-digit brute force – Starting from the first digit, turn the dial clockwise, slowly until it stops at the first digit. Try to pull the shackle up after each digit input. If the shackle does not release, turn the dial clockwise once again to the next digit and try again.

3. Note down the digits that have been tried – If a digit has been tried, mark it on a paper or in your head so that you do not repeat the same digit by mistake.

4. Repeat the process until all combinations have been tried – Continue trying all possible combinations until the lock opens.

Method 2: Contact the Manufacturer or Locksmith

If the brute force method does not work or if you do not want to spend time trying all possible combinations, contacting the manufacturer or locksmith is the best option. They have the experience and expertise to handle the issue professionally and quickly reset the lock.

Here are the steps to follow to contact the manufacturer if you have forgotten the combination code:

1. Locate the manufacturer's contact details – The manufacturer's information is usually present on the lock or on the packaging.

2. Verify your ownership and provide necessary details – The manufacturer will ask for proof of ownership or other relevant information to verify that you are the rightful owner of the lock. You may be asked to provide the model and serial number of the lock.

3. Pay any required fees – In some cases, the manufacturer may require you to pay a fee for resetting the combination code.

4. Follow the instructions provided by the manufacturer – Once the combination code is reset, the manufacturer will provide you with the new code and instructions on how to set it.


A combination lock is an essential security feature to keep your belongings safe and secure. If you forget the combination code, do not worry. There are ways to recover it without damaging the lock. The best way to reset the lock is to contact the manufacturer or locksmith. But if this is not possible, brute force may be the only option. Remember to take your time, be patient, and be prepared to try all possible combinations one-by-one.
