Best Access Systems and SFIC technology

Best's SFIC system is unique in the commercial lock market. Understanding how it works explains why Best dominates institutional applications and why it's worth specifying for certain applications.

Small Format Interchangeable Core (SFIC): The core is a removable cylinder plug that fits into a standardized lock body. All Best SFIC cores fit all Best SFIC lock bodies. Remove the core with a control key (separate from user keys), install a different core, and the lock is rekeyed.

No disassembly, no lock removal, typically 30 seconds per lock once you're trained.

Rekey Efficiency: Traditional lock rekey requires removing the lock from the door, disassembling, repinning, reassembling, and reinstalling. 15-30 minutes per door for experienced locksmith. Best SFIC rekey is 30 seconds per door after arriving with new cores.

For a school needing to rekey 200 doors, this is the difference between 50-100 hours and 2-4 hours.

Cores and Keyways: Best SFIC cores come in 6-pin and 7-pin configurations. 7-pin provides more key combinations (important for large master key systems) and more restricted keyway options. A/B/C keyways are standard; specific restricted keyways available for larger key control systems.

Control Key: The special key used to remove and install cores. Highly restricted access - only authorized facility staff and locksmiths. Losing the control key or unauthorized duplication compromises the entire system's security, since anyone with a control key can swap cores to bypass security.

Best 8K/9K Cylindrical Locks: Grade 1 commercial cylindrical locks designed for SFIC compatibility. 8K series is the workhorse; 9K adds additional features. Widely installed in schools, hospitals, and institutional facilities.

Standard cylindrical locks with the specific core hole for SFIC.

Best 45H Mortise Locks: Grade 1 commercial mortise lock with SFIC compatibility. Institutional workhorse for high-traffic and high-security applications. Hotels, hospitals, and large commercial buildings specify 45H for its durability and SFIC convenience.

Master Key Systems: Best SFIC works particularly well with master key systems because rekey is so easy. Master key plans with hundreds or thousands of keys are manageable when rekey requires only core swaps. Most large institutional master key systems use Best SFIC for this reason.

Construction Keying: Best SFIC supports construction keying - temporary keys used during construction that are defeated when permanent cores are installed after occupancy. Prevents construction crews from retaining access to the building. Common in school and hospital new construction.

Facility Management: Best SFIC systems include management software for tracking cores, keys, and authorizations. Essential for large facilities with complex key control requirements. Integrates with facility management systems for comprehensive key lifecycle management.

Best vs LFIC: Best is dominant in SFIC (small format interchangeable core). Schlage has their own LFIC (large format interchangeable core) system that works differently. LFIC and SFIC are not interchangeable - they're different standards.

Best is the choice for most institutional SFIC applications.

Best lock service FAQs

Common questions from Treasure Coast schools, hospitals, and institutional facility managers.

What is SFIC rekey?

SFIC (small format interchangeable core) rekey replaces the core - the removable cylinder plug - without removing the lock from the door. Takes about 30 seconds per lock with proper tools and authorization. Massive time savings vs traditional rekey which takes 15-30 minutes per lock.

How much does Best lock service cost?

SFIC core rekey: $25-$45 per core. New SFIC cores: $35-$75 each. 8K cylindrical lock installed: $395-$595.

45H mortise installed: $595-$995. Master key system design: quoted by scope. Volume pricing for schools and hospitals.

Can you handle school master key systems?

Yes. Best SFIC master key systems for schools are our specialty. Summer break rekey cycles, teacher turnover rekey, lost master key replacement, and facility-wide core updates.

Coordinated service minimizes disruption to school operations.

What's the control key?

Special key used to remove and install Best SFIC cores. Separate from user keys that operate the locks normally. Highly restricted access - only authorized facility staff and locksmiths have control keys.

Losing or compromising the control key requires system-wide security review.

Do you service existing Best installations?

Yes. Best Access Systems installations across the Treasure Coast served with core management, rekey, lock repair, and system updates. Full service for existing Best customers without need to replace existing hardware.

What about 7-pin vs 6-pin cores?

7-pin cores provide more combinations (important for large master key systems) and more restricted keyway options. 6-pin is standard for smaller facilities. Most institutional installations use 7-pin for growth capacity and security.

Free consultation on best choice for your application.

Can you rekey after employee turnover?

Yes. Best SFIC rekey is ideal for employee turnover because it's fast and minimally disruptive. Swap cores on affected doors in 30 seconds each.

Much more practical than traditional rekey for frequent changes.

Do you install new Best systems?

Yes. New Best SFIC systems for new construction or conversion from traditional lock systems. Full system design, master key plan, hardware installation, and staff training.

Common for new schools, hospitals, and institutional buildings.

What about construction keying?

Yes. Best supports construction keying where temporary cores allow construction crew access during building. After occupancy, control key is used to install permanent cores - automatically defeating all construction keys.

Prevents construction access retention after turnover.

Can you integrate with facility management software?

Yes. Best management software integrates with facility management systems for comprehensive key lifecycle tracking. Core assignments, key holders, rekey history, and audit trails.

Setup and training available.

How long do Best locks last?

Grade 1 Best commercial locks: 15-25+ years. Cores wear slower because they're often replaced for rekey rather than wear. Lock bodies (8K, 9K, 45H) have very long service life when properly maintained.

Cores are the rekey mechanism, not a wear point.

Can you handle multi-building campus rekey?

Yes. Large campus rekey projects (schools, colleges, hospitals, industrial parks) coordinated across multiple buildings. SFIC efficiency makes large rekey projects practical.

Scheduling around operations to minimize disruption.
