What is a Bump-proof Lock?

how to stop lock bumping

A bump-proof lock can resist a common method of lockpicking called “bumping.” Bumping is a technique that involves using a specially cut key, called a bump key, to open a lock by hitting it with a hammer or another object. The impact causes the pins inside the lock to jump and align with the shear line, allowing the lock to be turned.


Bumping is a simple and effective way for burglars to break into homes and buildings with conventional locks. Usually, American doors using the cylinder lock market will reach 4 billion dollars, but they are vulnerable to bumping. Moreover, bumping leaves no visible signs of forced entry or damage, making it hard to detect or prove.


How do we Prevent Lock-Bumping Techniques?

To prevent bumping, bump-proof locks have been designed with various features that make them immune to or resistant to this technique. Some of these features are:


  • Sidebars: Additional locking mechanisms prevent the lock from turning unless the correct key is inserted. Sidebars are not affected by bumping because they do not rely on pins.


  • Security pins: These have irregular shapes or sizes, such as spools, mushrooms, or serrations. Security pins make bumping harder because they bind or catch when bumped, preventing the pins from aligning with the shear line.


  • Electronic locks use electronic components, such as touchscreens, keypads, or biometrics, instead of mechanical keys. Electronic locks are bump-proof because they do not have pins or cylinders that can be bumped.


  • Hybrid locks: These are locks that combine mechanical and electronic features, such as smart deadbolts or keyless entry systems. Hybrid locks offer both convenience and security, as they can be opened with a code, a smartphone, or a backup key. However, some hybrid locks may still have cylinders that can be bumped, so it is important to check their specifications before buying.

Anti-lock Bumping Devices

If you’re on a budget, a few cheap antilock devices are available today to stop lock bumping. For example, a thumb turn guard intends to stop the thumb turn of a deadbolt from turning.

Thus, when it can’t rotate, the key can’t turn, which means the deadbolt can’t retract back inside the lock. Although cheap, it could be an advantageous alternative for an entryway. It also keeps a lost or misplaced lock key from opening the entryway.
