Have you ever found yourself locked out of your locker or suitcase because you forgot the combination? It can be a frustrating and inconvenient experience, but it doesn’t have to ruin your day. Changing the lock combo is a relatively simple process that can be done in just a few minutes. In this article, we’ll provide you with a step-by-step guide on how to change lock combo, so you can get back to your belongings quickly and easily.
Before you start, you’ll need to gather a few tools. You’ll need a small screwdriver, a pair of pliers, and a new lock. If you don’t have a new lock, you can purchase one at your local hardware store. Once you have your tools, you’re ready to get started.
The first step is to remove the old lock from the door or suitcase. To do this, insert the screwdriver into the small hole on the side of the lock and turn it counterclockwise. The lock should come right off. Once the lock is removed, you can discard it or keep it as a spare.
Gathering the Necessary Tools
Changing the lock combo on a lockbox or suitcase is a straightforward process that requires a few essential tools. Before you begin, ensure you have the following items on hand:
1. Lock Combo Tool
A lock combo tool is a specialized device designed specifically for changing the combination on locks. It consists of a long, thin shaft with a hook or needle on one end. This tool allows you to reach inside the lock and manipulate the internal mechanisms to reset the combination.
Lock combo tools come in various sizes and shapes, but the most common type is a universal tool that can accommodate most lock brands and models. If you are unsure which type of combo tool to use for your specific lock, refer to the manufacturer’s instructions or consult with a locksmith.
Here is a table summarizing the different types of lock combo tools and their uses:
| Type of Combo Tool | Use |
|---|---|
| Universal Combo Tool | Can be used on most lock brands and models |
| Specific Brand Combo Tool | Designed for a specific lock brand or model |
| Custom Combo Tool | Made to order for a unique or custom lock |
Accessing the Existing Combination Lock
To change the combination of an existing combination lock, you must first access the combination mechanism. This typically involves the following steps:
Locate the release button or hole
Most combination locks have a small release button or hole located near the dial. Find this button or hole and press or insert something into it to release the shackle and open the lock. If you cannot find a release button or hole, refer to the manufacturer’s instructions for your specific lock.
Align the dial to the correct numbers
Once the shackle is released, you need to align the dial to the correct numbers of your existing combination. To do this, turn the dial clockwise until the first number of the combination is aligned with the indicator mark on the lock. Then, turn the dial counterclockwise until the second number is aligned with the mark. Finally, turn the dial clockwise again until the third number is aligned with the mark.
Reset the lock
With the dial aligned to the correct numbers, you can now reset the lock to your new combination. To do this, press down on the reset button or enter the reset code as per the manufacturer’s instructions. Once the lock is reset, your new combination will be active.
Determining the Default Combination
Step 1: Consult the Manufacturer’s Instructions
Refer to the user manual or product packaging for the default combination provided by the manufacturer. This information can usually be found on a small sticker or label attached to the lock or its packaging.
Step 2: Try Common Combinations
If the default combination is not available, try popular combinations such as “0000,” “1234,” or “1111.” These sequences are often used as factory-set defaults.
Step 3: Examine the Lock’s Dials
Observe the dials on the lock. If they are marked with numbers or symbols, align them according to the following patterns:
| Dials with Only Numbers: | |
|---|---|
| 0000 | |
| 9999 | |
| Dial with Numbers and Symbols: | |
| AAAA | (corresponding numbers) |
| ZZZZ | (corresponding numbers) |
If the dials have no markings, rotate them until you find the default combination that unlocks the lock.
Resetting the Lock to the Default Combination
If you’ve forgotten the combination to your lock, don’t panic! You can reset it to the default combination by following these steps:
-
Locate the reset button on the back of the lock. It’s usually a small, recessed button.
-
Insert a ballpoint pen or paperclip into the reset button and push until you hear a click.
-
Turn the dials clockwise multiple times to make sure they’re fully aligned.
-
Enter the default combination.
The default combination for most locks is 0-0-0. Enter this combination by turning the dials to the corresponding numbers.
-
Push the lock shackle down to close the lock.
-
Your lock is now reset to the default combination.
Default Combinations for Common Lock Brands
| Brand | Default Combination |
|---|---|
| Master Lock | 0-0-0 |
| American Lock | 5-2-5 |
| Brinks | 1-2-3 |
| Paclock | 5-0-5 |
| Yale | 9-9-9 |
Setting a New Combination
To set a new combination, follow these steps:
- Unlock the lock using the current combination.
- Locate the small hole on the side of the lock that is labeled “Reset” or “Set.”
- Insert a small object, such as a paperclip or pen, into the hole and press down until you hear a click.
- Hold down the reset button and set the new combination by turning the dials.
- Choose a combination that is easy to remember but difficult for others to guess.
- Avoid using sequential numbers or patterns.
- Write down your new combination and keep it in a safe place.
-
Lubrication
Periodically lubricate the lock’s internal mechanisms with a dry lubricant, such as graphite powder or a spray lubricant specifically designed for locks. Avoid using oil or grease, as these can attract dirt and debris.
-
Cleaning
Clean the lock’s exterior regularly with a damp cloth to remove any dirt or dust buildup. Use a mild detergent if necessary, but avoid harsh chemicals that could damage the lock’s finish.
-
Tightening Screws
Check the lock’s screws occasionally to ensure they are securely fastened. Loose screws can affect the lock’s operation and security.
-
Resetting the Combination
If you forget the combination or suspect the lock has been compromised, reset the combination according to the manufacturer’s instructions.
-
Inspecting for Wear and Tear
Periodically inspect the lock for any signs of wear or damage, such as cracks, breaks, or excessive corrosion. If you notice any issues, replace the lock immediately.
-
Extreme Temperatures
Avoid exposing the lock to extreme temperatures, as this can affect its performance and durability.
-
Moisture
Protect the lock from excessive moisture, as this can cause corrosion and damage the internal mechanisms.
-
Freezing
If the lock is exposed to freezing temperatures, allow it to thaw completely before use. Attempting to open a frozen lock can damage the lock’s components.
5. Release the reset button and test the new combination.
Once you have set your new combination, release the reset button. To test the new combination, turn the dials to the new numbers and pull on the shackle. If the shackle opens, your new combination is set. If the shackle does not open, you may have made a mistake in setting the combination. Repeat steps 3 and 4 to reset the combination and try again.
Here are some additional tips for setting a new combination:
Testing the New Combination
Once you have set a new combination, it’s crucial to test it thoroughly to ensure it works correctly. Here’s a step-by-step guide to testing your new combination:
Step 1: Start with the New Combination
Dial in the new combination you just set. Ensure that each number is correctly aligned with the corresponding index mark.
Step 2: Rotate the Shackle 180 Degrees
After entering the new combination, rotate the shackle 180 degrees. This action is necessary to reset the internal locking mechanism.
Step 3: Re-enter the New Combination
Once you have rotated the shackle, re-enter the new combination. Again, ensure that each number is aligned correctly.
Step 4: Pull the Shackle Open
If the combination is correct, the shackle should open smoothly when you pull it. If it doesn’t, repeat steps 1-3.
Step 5: Close and Reopen the Lock
After successfully opening the lock, close it and attempt to reopen it using the new combination. This additional test ensures that the lock consistently opens with the correct combination.
Step 6: Perform Multiple Tests
For increased confidence in the new combination, perform multiple tests. Open and close the lock several times using the new combination. This will help you memorize the sequence and reduce the risk of forgetting it.
| Number of Tests | Purpose |
|---|---|
| 5-10 | Confirms consistent operation |
| 10-15 | Enhances memorization of the combination |
| 20+ | Provides a high level of certainty in the combination |

Gently try to jiggle the lock or insert a lubricant into the keyhole. If the lock is still jammed, you may need to contact a locksmith.
3. The lock is frozen:
If the lock is frozen, try to warm it up with a hair dryer or a heat lamp. Do not use hot water, as this can damage the lock.
4. The lock is broken:
If the lock is broken, you will need to replace it. Contact the manufacturer or a locksmith for assistance.
5. The lock is making a strange noise:
If the lock is making a strange noise, it may be a sign of a problem. Contact the manufacturer or a locksmith for further assistance.
6. The lock is not working properly:
If the lock is not working properly, try to reset the combination. If the problem persists, contact the manufacturer or a locksmith.

In this case, contacting the manufacturer or a professional locksmith for assistance is recommended.
Maintaining the Combination Lock
To keep your combination lock in top condition and prevent malfunctions, it’s essential to observe the following maintenance practices:
Lubrication Table
| Location | Frequency |
|---|---|
| Dial | Monthly |
| Shackle | Quarterly |
| Internal Mechanisms | Annually |
Security Considerations
Avoid Personal Information
Avoid using easily guessable combinations like birth dates, addresses, or phone numbers. These combinations can be susceptible to brute-force attacks, where attackers try every possible combination until they find the correct one.
Length and Complexity
Use combinations with at least six digits to increase the number of possible combinations. Consider using a combination with a mix of numbers, letters, and symbols to make it even harder to guess.
Keep It Secret
Keep your combination confidential and avoid sharing it with anyone who does not need it. Write it down in a secure location and memorize it. Do not keep written combinations near the lock where they can be easily found.
Regular Changes
Change your combination regularly, especially if you believe it may have been compromised. This helps prevent unauthorized access if someone has managed to learn your combination.
Reset After a Break-In
If a break-in occurs, reset your combination immediately. Thieves may have learned your combination during the break-in, so changing it ensures they cannot re-enter your property.
Battery Backup
For electronic locks, ensure you have a battery backup system in place. If the batteries run out, you may not be able to access your property until the batteries are replaced.
Tamper Resistance
Choose a lock with tamper-resistant features. These features can make it difficult for attackers to manipulate the lock or try different combinations.
Anti-Drilling Protection
Consider locks with anti-drilling protection to prevent burglars from drilling into the lock to access the internal mechanism. Anti-drilling protection can deter attackers or increase the time it takes for them to break in.
Key Override
Some combination locks have a key override option. This allows you to open the lock using a key if you forget your combination or if the electronic system fails. Keep the key safe and avoid leaving it in the lock.
10. Adjust the Shackle Guard (if applicable)
Some combination locks have a shackle guard that covers the shackle when the lock is closed. To adjust the shackle guard, open the lock, press down on the shackle release button, and rotate the shackle guard until it is in the desired position. Release the shackle release button and close the lock to engage the shackle guard.
a. Determine the type of shackle guard:
| Type | Description |
|---|---|
| Spring-loaded | Lifts automatically when the shackle is pushed down |
| Screw-on | Requires a screwdriver to remove or adjust |
| Fixed | Cannot be adjusted or removed |
b. Adjust the shackle guard position:
For spring-loaded guards: Press down on the shackle and rotate the guard.
For screw-on guards: Loosen the screw, rotate the guard, and tighten the screw.
c. Test the guard’s alignment:
Close the lock and push down on the shackle. The guard should engage smoothly and fully cover the shackle.
