Accentra (Yale) 1806 GA 626 0 BITTED Cylinder for 4600LN Series

The Accentra (Yale) 1806 GA 626 is a 6-pin, 0-bitted cylinder in the GA keyway and 626 satin chrome finish, designed for the Yale 4600LN Series lever locksets. A 0-bitted cylinder ships with all pin cuts at depth position 0, meaning all driver pins are at maximum height and the cylinder is not cut to any specific key. This configuration is used when a locksmith or key system manager needs to install the cylinder and then cut or pin it to the correct key combination as part of a new master key system setup or key change program. SKU: 1806.

What a 0-bitted cylinder is and why it is ordered instead of a standard keyed cylinder

A 0-bitted cylinder ships with all cuts at depth 0 across all pin positions. In a pin tumbler cylinder, depth 0 corresponds to the shallowest key cut, which places the driver pins at the maximum shear line height. A 0-bitted cylinder is not operated by any regular change key in the system. It accepts only a master key or control key that can operate all cylinders regardless of individual key cuts, or it is used as a starting point for a locksmith to repin to the correct key combination before installation.

This is the correct ordering approach when a facility is building a new master key system and needs to receive cylinders in a neutral state before the key system is applied. The key control manager or locksmith pines each 1806 cylinder to the correct key cut for its designated door position, allowing precise control over which keys operate which cylinders before any cylinder is installed in a lock. For key blanks compatible with the Yale GA keyway used in the 1806, the key blanks catalog covers the available options. For the full range of cylinder components, the cylinders, cores, and keys section is available.

What the Yale 4600LN Series is and where the 1806 cylinder installs

The 4600LN is a Yale Grade 1 heavy-duty cylindrical lever lockset. Grade 1 is the highest ANSI/BHMA performance tier for cylindrical locksets, required on high-traffic commercial entry doors, institutional applications, and any door that must meet the Grade 1 specification on a hardware schedule. The LN designation confirms this is the lever version of the 4600 Series platform. The 1806 is the lever cylinder format for this series, seating inside the lever housing to provide key-operated locking.

The GA keyway is a Yale proprietary keyway used across multiple Yale and Accentra cylinder product lines. If the facility is adding new 4600LN locks to an existing Yale GA keyway system, the 1806 GA cylinder allows those new locks to be keyed into the same master key program as the existing hardware after pinning. For Accentra lever locks including the full 4600LN Series, the Accentra lever locks catalog covers the available configurations.

How the 1806 GA 626 relates to the 1802 and other Yale lever cylinders

The 1806 and the 1802 are both lever cylinders for Yale lever locksets, but they serve different series within the Yale platform. The 1802 is the standard lever cylinder for the 5400LN, 6400LN, 5300LN, and inTouch series. The 1806 is the cylinder for the 4600LN series. Ordering the wrong lever cylinder model for the series will result in an incompatible fit. Confirm the specific lockset series is 4600LN before ordering the 1806.

For the lever cylinder that fits the 5400LN, 6400LN, and 5300LN series, the Accentra Yale 1802 lever cylinder is also stocked. For the complete commercial lock and hardware range at American Locksets, browse the commercial locks section.
