Master Lock Storage Bag Key HACK – Find the Right Key

In the world of locksmithing, figuring out the right key for a unique lock can be both a challenge and a rewarding puzzle. Recently, there’s been a surge in searches for a Master Lock padlock key that isn't immediately recognizable. After some sleuthing, I found it’s a key for a Master Lock storage bag, designed to secure valuables like cash, jewelry, and confidential documents. Curious to get to the bottom of this key mystery, I ordered one myself and dove in.

Here’s what I found—and how you can solve this puzzle, too.

What’s the Deal with This Key?

So, what makes this key stand out? First things first:

• It’s not your typical Master Lock key. There’s no distinct head or groove pattern that screams "Master Key."
• The key is often misidentified. People are turning to ideniKey to try and match it.

Now, let’s dig into the details and how to find the right match.

Steps to Identify and Duplicate the Key

1. Use idenikey: I pulled out ideniKey, snapped a picture of the key, and let it do its magic. The search suggested a couple of options, including the 1131 Arco key, which is commonly used for bank bags.
2. Test the 1131 Key: While the 1131 seemed like a good candidate, it didn’t fit perfectly—just enough to go in but not work as expected. That’s when things got interesting.
3. Try Other Blanks: After some trial and error, I found that the CO16 key blank goes in easily but is too short to function properly.

The Key Hack: How to Make It Fit

So, none of the initial keys worked perfectly. Here’s where the fun of locksmithing comes in—time to modify the key.

• Grind the 1131 Key: Using a bench grinder or a handheld grinding tool, I lightly shaved down the side of the 1131 key.
• Test and Adjust: After a bit of grinding, I tested the key, and voila—it fit like a glove! It didn’t take much grinding, just a slight adjustment to make it work.

If you’re ever faced with a similar key issue, this is a great trick to have up your sleeve. Here’s a quick recap of the process:

How to Modify the Key for a Perfect Fit:

• Use ideniKey to identify the closest match (likely the 1131 Arco key).
• Test the key in the lock, noting where it sticks.
• Lightly grind down the sticking points (typically along the grooves).
• Test again until the key fits smoothly.

Common Questions:

• What if I don’t have a grinder?
  • You can try using a CO16 blank, which fits easily, though it may be too short to work without modification.
• Can I find a key that requires no modification?
  • This is still a mystery! If you know of a blank that fits without modification, please drop it in the comments.

Final Thoughts

Locksmithing isn’t always about having the perfect key on hand—it’s about figuring out solutions on the fly. In this case, with a little smithing, the 1131 Arco key turns into a reliable solution for the Master Lock storage bag. It’s a satisfying blend of technology (ideniKey) and hands-on skill (grinding).

For all the locksmiths out there, remember that sometimes, you’ll need to get a little creative to solve key problems. And hey, who doesn’t enjoy a good key hack?

Key Takeaways:

• Use ideniKey to narrow down key options quickly.
• The 1131 Arco key is a close match for the Master Lock storage bag.
• Light grinding may be necessary to get the perfect fit.
• The CO16 blank fits but is too short without modification.
