The Bump Stops Here!

Protect Your Property with Master Lock Bump Stop Padlocks

At The Lock Source, we are committed to providing high-security solutions that protect against modern lock-picking techniques. That’s why we’ve launched a new page dedicated to Master Lock Bump Stop Padlocks, designed to safeguard against one of the most common and concerning lock-picking methods: lock bumping.

What Is Lock Bumping?

Lock bumping is a technique used by criminals to quickly and easily open pin tumbler locks using a specially cut “bump key.” By inserting the bump key into the lock and striking it with a small tool, the internal pins momentarily jump into alignment, allowing the lock to be turned and opened. Unfortunately, this method leaves little to no signs of forced entry, making it a serious security risk for homes, businesses, and storage units.

How Master Lock Bump Stop Technology Protects Against Lock Bumping

Master Lock developed Bump Stop Advanced Cylinder Technology to eliminate the effectiveness of bump keys. Instead of using traditional pin tumbler cylinders, Bump Stop locks feature an innovative active blocking mechanism that prevents the internal pins from aligning under the force of a bump key. This added layer of security ensures that only the proper key can open the lock, giving you peace of mind that your property is protected.

Master Lock Padlocks with Bump Stop Protection

While many Master Lock padlocks were once available with optional Bump Stop cylinders, only select models still feature this critical security enhancement. The remaining laminated padlocks with the bump-stopping feature are:

For high-security applications, Master Lock still offers Bump Stop protection in their Pro Series 5-and 6-Pin padlocks, which provide additional strength and durability:

  • 6121N Pro Series – A heavy-duty weather-resistant padlock with a reinforced body
  • 6125N Pro Series – A high-security padlock with a hardened boron alloy shackle
  • 6230N Pro Series – A solid steel padlock offering superior protection
  • 6271N Pro Series– Solid Steel Van Door Padlocks With the Ultimate Defense vs. Lock Picking

Why Choose a Bump Stop Padlock?

  • Prevents Lock Bumping – Eliminates the risk of bump key attacks
  • High-Security Design – Reinforced materials for added durability

For businesses, homeowners, and facility managers looking for an extra layer of security, Master Lock Bump Stop padlocks provide a smart and effective solution.
