| 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 (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 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.
| |
| | |
| 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.<ref>{{Ref pulford}}</ref>

| '''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.
| |
| | |
| # Remove the [[cam]] or C-clip.
| |
| # Remove the [[plug]] from the cylinder. A [[plug follower]] is not needed because there are no driver pins.
| |
| # 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:
| |
| | |
| * [[Lockpicking]]
| |
| * [[Impressioning]]
| |
| * [[Decoding]]
| |
| | |
| '''Notes'''
| |
| * The BiLock EX cannot be bumped because it is ''not'' a [[pin-tumbler]] lock.
