Lost Your Key? How To Open a Padlock with an Aluminum Can

We’ve all been there—whether it’s a forgotten key, a misplaced lockbox code, or simply a padlock whose key has gone missing at the worst possible time. But did you know that you can actually open some padlocks with nothing more than an aluminum can? Yep, that soda can sitting next to you could be the solution! While it’s essential to note that this method is more of a helpful trick for lost keys and forgotten locks, it’s not meant for illegal purposes. So, if you’re in a pinch, here’s a step-by-step guide that shows you how to open a padlock using an aluminum can.

Before We Get Started: A Few Safety Notes

1. Legal Use Only: Use this technique only for locks you own or have permission to open.
2. Not All Padlocks Are Vulnerable: High-security padlocks are often resistant to this method, so keep that in mind.
3. Be Careful When Handling Aluminum: Aluminum can be sharp, so wear gloves or proceed carefully to avoid cuts.

How Does It Work?

The trick behind opening a padlock with an aluminum can lies in making what’s called a “shim.” A shim is a small piece of metal designed to slip between the locking mechanism and the shackle (the part of the lock that opens). Many padlocks, especially older or inexpensive ones, have a vulnerability where a shim can trick the locking mechanism into thinking it’s unlocked.

Watch this detailed YouTube video for a visual demonstration of the process:

Aluminum Can Shim

Here’s how to craft your shim using an ordinary aluminum can.

you will need

• 1 empty aluminum can (soda cans work great)
• Scissors
• Gloves (optional but recommended)
• A padlock to test (preferably one you can practice on)

Instructions:

1. Prepare the Can: Wash out the aluminum can and dry it. Cut off the top and bottom using scissors so that you’re left with a flat sheet of aluminum.
2. Cut the Shim: Cut a strip of aluminum about 2-3 inches long and 1 inch wide. This will be your shim. Be careful, as the edges can be sharp. Round the top corner of your strip so it’s easier to slide into the lock.
3. Shape the Shim: Take the strip and bend it slightly to match the curve of the padlock’s shackle. The shim needs to be slightly curved to maneuver inside the lock’s mechanism.
4. Insert the Shim: Slip the shim into the gap where the padlock’s shackle meets the body. Wiggle it around until you feel it slide into place alongside the locking mechanism.
5. Unlock: Push down on the shim while applying upward pressure on the shackle. If successful, the shackle should pop open without needing the key.

Tips for Success

• Practice Makes Perfect: Like with any new skill, practice is key. You might not get it on the first try, but after a few attempts, you’ll get a feel for how to work the shim.
• Padlock Quality Matters: Older, less expensive locks are more vulnerable to this method. Newer, higher-quality padlocks often have anti-shim technology that blocks this technique.
• Be Gentle: Aluminum is soft and can bend easily. Try not to apply too much force to your shim or you may need to make another one.
• Use on Personal Property: Again, this should only be used to open padlocks that belong to you or locks you’ve been granted permission to open.

FAQs

Q: Can this method work on all types of padlocks?
A: No, not all padlocks can be opened with an aluminum shim. Many high-quality padlocks have anti-shim technology, which makes them more secure. This method is best for older or budget padlocks.

Q: Is this illegal?
A: Using this technique to open locks you don’t own or have permission to open is illegal. Always use this method responsibly and only on locks that belong to you.

Q: What if I can’t get the shim to work?
A: If you’re having trouble, try making a thinner or more precisely curved shim. Also, practice on different locks to understand how they work. Some locks may require more patience and technique.

Q: Is it dangerous to cut an aluminum can?
A: Aluminum can be sharp, so wear gloves or be careful while cutting. If you’re worried about safety, consider using a piece of cardboard to fold over the edges after cutting.

Q: What other tools can open a padlock if I don’t have an aluminum can?
A: Other tools, such as padlock shims sold online, can be used, but the aluminum can method is a free alternative. Always avoid destructive methods unless it’s your last resort.

Conclusion

Losing a key can be stressful, but now you have a handy life hack for certain types of padlocks. Remember, this technique works best on older, simpler locks and should only be used in situations where you have the legal right to open the lock. By using an aluminum can and a bit of patience, you can turn what could have been a frustrating situation into a quick fix.
