How to Set and Reset Your TSA Lock (Model: 21105 cable lock) Combination in Under 60 Seconds
Travel security doesn't have to be complicated. Whether you're a frequent flyer or an occasional traveler, knowing how to properly set and reset your TSA lock combination is an essential skill that can save you time, frustration, and potentially costly locksmith fees. Today, we'll walk you through the simple process of customizing your FORGE TSA-approved combination lock.
Why Your Lock Combination Matters
TSA-approved locks offer the perfect balance of security and convenience. These locks allow Transportation Security Administration agents to inspect your luggage when necessary while keeping your belongings secure from casual tampering. The ability to set your own memorable combination ensures you'll never be locked out of your own luggage.
What You'll Need
Before we begin, gather these simple tools:
- Your FORGE TSA combination lock
 - A pen or similar pointed object
 - A notepad to write down your new combination (trust us on this one!)
 
Step-by-Step Instructions
1. Start with the Default Setting
Every FORGE lock comes with a default combination of 0-0-0. Before you can set your personal combination, you need to open the lock using this factory setting. This is your starting point for the entire process.
2. Open the Lock
Set all three dials to 0-0-0 and pull the shackle (the U-shaped metal piece) to open the lock. You should feel it release smoothly. If the lock doesn't open, double-check that all dials are properly aligned to zero.
3. Locate and Activate the Reset Switch

Here's where the magic happens. On the back of your lock, you'll find a small switch or button. Using the tip of your pen, gently flip this switch. You'll feel it click into the reset position. This activates the combination-change mode.
Pro Tip: The reset switch is designed to be small and discreet for security reasons. Don't worry if it takes a moment to locate – it's there!
4. Set Your New Combination

Now comes the fun part – choosing your new combination. Turn the dials to any three-digit combination you prefer. Choose something memorable but not too obvious (avoid 1-2-3 or your birthday). Popular choices include:
- A significant date (but not your birth year)
 - A number pattern you can easily remember
 - A combination of lucky numbers
 
5. Lock in Your New Combination

Once you've set your desired combination, use your pen tip to flip the reset switch back to its original position. You'll feel another satisfying click. This locks in your new combination permanently.
6. Test Your New Setting
Before closing the lock completely, test your new combination. Close the shackle, scramble the dials, then enter your new combination. The lock should open smoothly. If it doesn't work, don't panic – simply repeat the process from step 3.
Troubleshooting Common Issues
- Lock won't open with 0-0-0: Some locks may have been previously set. Try common combinations like 1-2-3 or check if there's documentation with your lock.
 - Reset switch won't move: Make sure you're using enough pressure with your pen tip, but don't force it. The switch should move with moderate pressure.
 - New combination doesn't work: Ensure you flipped the reset switch back to its locked position after setting your combination.
 
Security Best Practices
- Choose wisely: Avoid obvious combinations like 0-0-0, 1-2-3, or easily guessable personal numbers
 - Keep it written down: Store your combination in your phone or wallet, separate from your luggage
 - Test regularly: Before each trip, test your lock to ensure it's working properly
 - Consider multiple combinations: If you travel with different bags, consider using the same combination for all locks to avoid confusion
 
The TSA Advantage
Remember, your FORGE lock features TSA approval, indicated by the distinctive red diamond logo. This means:
- TSA agents can inspect your luggage without cutting your lock
 - Your lock will be relatched after inspection
 - You maintain security while complying with travel regulations
