| The '''BiLock EG''' (or '''BiLock New Generation''') is a [[UL 437]]-rated [[pin-tumbler]] lock made by [[BiLock]]. All BiLock models include two rows of pins and an associated [[sidebar]] for each row. The key is U-shaped to simultaneously register both rows of pins. BiLock keys are first cut, then folded to create their classic U-shape.

| == Principles of operation ==
| |
| | |
| 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.
| |
| | |
| BiLocks are unique because they contain no driver/top pins and there the lock has no traditional [[shear line]]. There are ? depths for pin-tumblers, allowing for ? theoretical key [[differs]] for each pin stack. The [[MACS]] for this lock is ? depths, giving the ? around ? real key differs. [[Master keying]] is available by using pins with multiple sidebar holes.
| |
| | |
| The BiLock EG 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.

| == Disassembly instructions ==
| |
| | |
| The 6000 is disassembled in the same way as a traditional pin-tumbler cylinder. The sidebar does not cause too many problems when the plug is removed. When the key is removed from the exposed plug the finger pins will be forced out by spring pressure.

| == Vulnerabilities ==
| |
| | |
| The 6000 system may be vulnerable to one or more of the following:
| |
| | |
| * [[Lockpicking]]
| |
| * [[Impressioning]]
| |
| * [[Decoding]]
| |
| * [[Bumping|Key bumping]]
| |
| | |
| '''Notes'''
| |
| * Bumping is possible given a bump key with the correct sidebar bitting.
