This method involves having a specially cut key with multiple grooves and notches to match the most common combinations in today’s locks. The key is inserted into the cylinder and then by applying tension and “bumping” the key into the lock, it forces the pins inside off the sheer line and access is gained.
It can take less than 20 seconds to gain access to your premises and because of the nature of the attack no visible break in attempts are left behind. This can make it very difficult to claim on your insurance.
How to protect against Lock Bumping
To protect against this attack, many locks are now fitted with Anti Bump Pins. These are usually set both directly on the sheer line and 1 pin much higher than the rest. This means that if someone has a key that can move the lower pins it would be too low to reach the high pin. Similarly, if the key can move the high pin, it would be too high to move the lower ones.

This method is the most intrusive and the most noticeable. An intruder will take a strong drill bit and drill through the cylinder on the sheer line. It will break the pins inside and the plug / core can then be turned with a flat headed screwdriver.
How to protect against Lock Drilling
To protect against such a violent attack, locks can be fitted with hardened steel pins and hardened steel cylinders.
We offer a wide range of systems that are of Grade 2 attack resistance and resistant to drilling for 5 minutes. View them all here
Lock Snapping & Plug Pulling / Core Extraction
This method involves snapping the cylinder at the weakest point, causing the lock mechanism to break free and consequently opening the door.
The plug or lock core is the cylinder housing that contains the pins and locking mechanisms. Plug pulling is a method that involves tightening a small screw directly into the plug / core and then applying leverage - with such tools as a claw hammer, pulling the plug directly out of the lock.
How to protect against Lock Snapping / Plug Pulling
To protect against such attacks, there is a method called Anti-Snap. Here 2 grooves are deliberately cut into each end of the cylinder to create weak points. When pressure is applied to the lock, attempting to either snap the lock or remove the plug, these weak points break.
This snaps the lock into the door before the lock mechanism, making sure the intruder can’t gain access and maintaining the security of your premises.

This method involves manually moving the pins within the core so they all align on the sheer line and access is gained. Such attacks can be carried out using general objects such as hair grips and paper clips, however, there are many professional lock picking tools out there to speed up the process.
Lock picking generally takes a lot of practice and skill so many burglars today prefer the quicker methods of Lock Snapping and Lock Bumping.
How to protect against Lock Picking
When making the lock, you can include Anti Pick pins within your system. These pins are shouldered and tapered to create false sheer lines within the lock. This fools the picking or bumping techniques when trying to access that sheer line.
