If you’re looking for a heavy-duty truck lock, you might have come across the Master Lock M736, available at Home Depot for around $37. At first glance, it appears to be a solid security solution, with a reinforced steel body and a sturdy locking mechanism. But how well does it actually perform? A Bosnian Bill video puts this lock to the test, and the results are shocking.

How Secure Is the Master Lock M736?

The YouTuber Bosnian Bill demonstrates how quickly this lock can be picked—within mere seconds. Despite its hefty appearance and armored design, the lock has a standard five-pin tumbler mechanism that offers little resistance to picking. Using basic lockpicking tools, he effortlessly gains access, highlighting a major flaw in the lock’s security.

A Closer Look at the Lock

• Price: ~$37
• Material: Heavy-duty steel
• Locking Mechanism: Five-pin tumbler
• Installation: Designed for vehicle doors, mounted using a steel frame

Even with its reinforced frame and solid steel construction, the lock’s weakness lies in its internal mechanism. It lacks security pins, making it highly vulnerable to both single-pin picking (SPP) and raking techniques.

How Fast Was It Picked?

In the video, Bosnian Bill:

• Picks the lock within seconds using a simple SPP technique.
• Attempts raking and eventually succeeds, further proving the lock’s vulnerability.
• Concludes that the Master Lock M736 is unreliable for securing valuable items.

A Better Alternative?

The video suggests that for just a few dollars more, you can get an American Lock model that offers significantly better security. If you’re looking for a truly reliable lock, it’s worth considering a higher-quality alternative.

Final Verdict

If you’re serious about securing your vehicle or valuables, the Master Lock M736 is not the best choice. Its ease of picking makes it a risky investment, especially for business owners protecting high-value equipment. Consider a better-quality lock to ensure your security needs are met.

Stay safe and stay secure!
