The BiLock EX/NG uses a total of twelve pins arranged in two rows of six. Each row of pins interacts with a [[sidebar]] on each side of the plug. Each pin has a round hole, the true gate, and a false gate located two pin depths away from the true gate. The false gate is the same shape as the true gate, but is too shallow to allow the sidebar to fully retract. To open the lock, all pins are raised and the side bar legs retract into the true gate on each pin. There are 4 depths for pins, which allows 16,777,216 (4<sup>12</sup>) theoretical key [[differs]]. [[Master keying]] is available by using pins with wider sidebar holes. Master keyed pins do not use false gates.


<!-- The BiLock uses two rows of six pin-tumbler pins and five sidebar [[Side pin|finger pins]]. To open the lock, all pin-tumblers properly raised to a height that allows the side bar legs to retract into small holes located in the key pins. Every pin has a second, shallow hole drilled in it. This hole is deep enough to allow the pin to set under sidebar pressure but too shallow to allow the sidebar to fully retract.
The main difference between the classic [[BiLock]] and the BiLock EX is a moving element in the key. Similar to the component used in the [[Mul-T-Lock Interactive]], this component in the key interacts with a movable element at the front of the lock, referred to as the "13th locking dimension" by BiLock advertising literature.<ref>Australian Lock Company. [http://www.australianlock.com.au/system/files//f6/f1/o586/BiLockNewGenDLBrochure_1.pdf BiLock Sales Brochure]</ref> While at rest, the movable element connects to a blocking bar that prevents the sidebar at 3 o'clock from retracting. The moving element in the key raises the blocking bar so that the sidebar may retract. Unlike other interactive components, the BiLock's component does not use a shear line or other positive locking mechanism; it only needs to be moved up to function.


BiLocks are unique because they contain no driver/top pins and therefore the lock has no traditional [[shear line]].

The BiLock EX also has what is traditionally known as an [[interactive]] element in the key that was implemented to add an extra layer of security and extend the original patent of the lock.  BiLock refers to this element as a "trigger" which is held between the two blades by the plastic key head. In its rest position the Trigger protrudes through a small opening in the key blade. As the key enters the keyway, the bottom of the keyway channel forces the front of the trigger upward into a lift pin. When the lift pin is raised, it drags a blocking bar up and out of the way of the right side bar, allowing it to retract. -->

The BiLock EX (or BiLock NG, BiLock New Generation) is a dual-sidebar lock made by Australian Lock Company. The BiLock EX uses twelve pins arranged in two rows of six. Each row of pins uses a separate sidebar located at 3 and 9 o'clock in the plug. It also uses a moving element in the key blade which is used to position an addition component at the front of the plug. The BiLock EX is easily identified by the U-shaped key and keyway.

The BiLock EX supercedes the earlier BiLock design and is available in the BiLock QC interchangeable core format.


Principles of operation

The BiLock EX/NG uses a total of twelve pins arranged in two rows of six. Each row of pins interacts with a sidebar on each side of the plug. Each pin has a round hole, the true gate, and a false gate located two pin depths away from the true gate. The false gate is the same shape as the true gate, but is too shallow to allow the sidebar to fully retract. To open the lock, all pins are raised and the side bar legs retract into the true gate on each pin. There are 4 depths for pins, which allows 16,777,216 (412) theoretical key differs. Master keying is available by using pins with wider sidebar holes. Master keyed pins do not use false gates.

The main difference between the classic BiLock and the BiLock EX is a moving element in the key. Similar to the component used in the Mul-T-Lock Interactive, this component in the key interacts with a movable element at the front of the lock, referred to as the "13th locking dimension" by BiLock advertising literature.[1] While at rest, the movable element connects to a blocking bar that prevents the sidebar at 3 o'clock from retracting. The moving element in the key raises the blocking bar so that the sidebar may retract. Unlike other interactive components, the BiLock's component does not use a shear line or other positive locking mechanism; it only needs to be moved up to function.

The EX/NG plug also has a removable faceplate which allows the warding of the lock to be changed without replacement of the plug or cylinder. The actual design of EX/NG keys slightly differs from previous models; the base of the key and keyway are curved inward.[2]

  • The BiLock EX key.

  • Pins used in the EX, with false gates and master keyed pin shown.

  • One of the sidebars used in the EX.

  • Moving element pin and blocking bar.

Notes

  • BiLock keys are cut then folded to create their U-shape.
  • The BiLock EX/NG core is compatible with the BiLock and BiLock QC cylinders.

Disassembly instructions

The BiLock EX is easy to disassemble, but the moving element uses a number of small components that need to be considered.

  1. Remove the cam or C-clip.
  2. Remove the plug from the cylinder. A plug follower is not needed because there are no driver pins.
  3. Remove the faceplate from the front of the plug to access the moving element and the pin chamber cover.

Vulnerabilities

The BiLock EX may be vulnerable to one or more of the following:

Notes

  • The BiLock EX cannot be bumped because it is not a pin-tumbler lock.

Gallery

  • Moving component (key) in the default position.

  • Moving component (key) in the active position.

  • Closeup of the key bitting.
