Anti-bumping locks

What is anti-bumping?

The meaning of this type of lock comes from the English term, and literally means "anti-shock." Anti-bumping locks are security systems designed to resist or thwart attempts to open them using the bumping technique (a method that consists of opening locks without the corresponding key). These locks incorporate specific features that combine design and internal security mechanisms to increase resistance to bumping, making it more difficult for an intruder to open the lock using this technique. There are various types, such as anti-bumping rim locks, double-clutch anti-bumping locks, or even anti-bumping deadbolts.

Factors to consider before buying an anti-bumping lock

1. Security pins: These are elements inside the lock cylinder that collide with the use of keys used in the bumping technique. They may have irregular shapes, ridges, or special grooves that hinder the movement of the pins during bumping. Typically, most cylinders that can be bumped are those with serated keys.

2. Driver pins: These are additional elements strategically placed in the body of the anti-bumping lock cylinder. They serve to lock the pins in place and prevent them from jumping when a striking force is applied. Furthermore, they require proper rotation of the legitimate key to release the pins and allow the lock to be opened.

3. Additional locking systems: Some anti-bumping locks incorporate additional locking systems that can be anti-extraction bars or protection plates, whose objective is to prevent attempts at tampering with and extracting the lock cylinder.

4. Advanced technology: Other types of anti-bumping locks use advanced technology, such as magnetic, electronic, or electromechanical systems, to increase their security. The main objective of such systems is to verify the authenticity of the key, require a specific sequence of movements, or even allow for remote access management.

Recommended anti-bumping brands
