Accentra (Yale) 1210 Interchangeable Core 6-pin

The Accentra (Yale) 1210 is a 6-pin Large Format Interchangeable Core (LFIC) for Yale and Accentra lock housings prepped for LFIC or Full Size Interchangeable Core (FSIC) applications. This core is also referenced in the field and in parts ordering as ai41210, ai61210, ai60210, Yale 1210, Yale SFIC core, 1210-600, and Accentra 1210. The 1210 installs in Accentra and Yale mortise locks, cylindrical locks, and exit device trims prepared to accept a large format interchangeable core. Available in keyways from the SA, GA, TA, and PARA series in 626 satin chrome and 606 satin brass. SKU: 1210.

What the Yale 1210 LFIC is and where it installs in a key control system

The Yale 1210 is the standard large format interchangeable core used across Accentra and Yale lock housings. It inserts directly into mortise lock bodies, cylindrical lock housings, and exit device trim cylinders that are prepped for LFIC format without any additional hardware. Removing and inserting the core requires only an authorized control key, which means rekeying or replacing a core takes seconds at the door rather than requiring a locksmith to disassemble the lock.

This makes the 1210 the core of choice for facilities that need to control key access efficiently across a large number of openings. When an employee is terminated, a key is lost, or security zones change, the affected cores can be rotated out immediately by facilities staff or a key control manager without calling a locksmith. The 1210 can also be keyed in conjunction with standard (non-IC) Yale cylinders, which means facilities that are transitioning from standard cylinders to IC cores can maintain a unified key system during the changeover. For the LFIC rim cylinder housing that accepts this core in exit device applications, the Accentra Yale 1193 LFIC rim cylinder is stocked. For Schlage IC cores and other IC format options, the Schlage IC cores section is available.

How to identify which Yale 1210 keyway you need for your existing key system

The 1210 is available in a wide range of Yale proprietary keyway designations across the SA through SH, GA through GH, TA through TH, and PARA series. Each keyway designation determines which key blade profile the core accepts. If you're adding 1210 cores to an existing Yale or Accentra key system, the keyway must match the keyway already in use across the facility's cylinders and cores.

The correct keyway designation can be confirmed from the original hardware specification, the key control records, or from the key itself — the keyway designation is typically stamped on the key bow or can be identified by the key blank number. If the facility is setting up a new key system from scratch, the keyway is selected based on the master key program being established. For key blanks and cylinders across Yale keyway series, the cylinders, cores, and keys section covers the available options.

What LFIC, FSIC, and SFIC mean and which format the Yale 1210 uses

LFIC (Large Format Interchangeable Core) and FSIC (Full Size Interchangeable Core) are two names for the same physical core format. The Yale 1210 is this format. It is physically larger than the SFIC (Small Format Interchangeable Core), which is a different format used by a different set of lock manufacturers. The LFIC format used by Yale and Accentra is also used by several other commercial hardware brands, making it possible in some cases to use Yale 1210 cores in compatible LFIC housings from other manufacturers that accept the same format geometry.

Confirm that the lock housing on the door is prepped for LFIC before ordering. A housing prepped for SFIC will not accept the Yale 1210. If the housing is a standard pin cylinder housing (not an IC-prepped housing), the 1210 is not compatible. For standard Yale rim cylinders for exit devices that do not use IC cores, the Accentra Yale 1109 rim cylinder is available.

Confirm the keyway designation matches the existing key system before ordering. Available finishes: 626 satin chrome and 606 satin brass. Also referenced as: ai41210, ai61210, ai60210, Yale SFIC core, 1210-600.
