When it comes to the complexities of locksmithing, Schlage's Large Format Interchangeable Core (LFIC) systems are a hot topic. LFIC systems are crucial for professionals who need robust and flexible security solutions. In this blog, we'll dive into what Schlage LFIC is, how it works, and why it's distinct from other locking systems, particularly the Small Format Interchangeable Core (SFIC).
What Exactly is LFIC?
LFIC stands for Large Format Interchangeable Core, which is a type of locking mechanism designed by Schlage. This system allows for lock cores to be exchanged without disassembling the entire lock – making it a favorite for efficiency and adaptability in commercial settings. But what sets LFIC apart from its counterpart, SFIC?
-
Size and Compatibility: LFICs are larger than SFICs, which are typically used with BEST brand locks.
-
Interchangeability: Despite their similarities in name, LFIC and SFIC cores are not interchangeable.
-
Keying Process: The methods for keying LFICs and SFICs are completely different, necessitating distinct considerations and tools.
How Do You Pin LFIC Locks?
Pin tumbler locks are standard in the locksmith industry, and LFICs are no exception. If you're familiar with pinning traditional Schlage locks, then you'll find LFIC systems refreshingly similar:
-
Pinning Kits: You can use standard Schlage or universal pinning kits for LFICs, which accommodate pins for both five and six-pin systems.
-
Procedure: The pinning procedure for LFICs mirrors that of regular Schlage locks, such as key-in-knob cylinders commonly found in commercial hardware.
The Role of the Control Key in LFIC Systems
The control key is a specialized tool in LFIC systems that facilitates the installation and removal of the core:
-
Special Features: The control key is longer than standard keys and is designed to interact specifically with the rear cam of the LFIC.
-
Functionality: By inserting the control key into the LFIC, a pin at the end of the key engages, allowing the core to be extracted or inserted with ease.
What Hardware Works with LFIC?
Selecting the right hardware for LFIC systems is critical for ensuring compatibility and functionality:
-
LFIC-Prepped Hardware: Only hardware specifically prepared for LFIC systems will work. This includes certain types of rim cylinders, mortise cylinders, and commercial levers.
-
Non-Compatibility: Hardware designed for SFICs will not accommodate LFICs, as the size and configuration differ significantly.
Final Thoughts
Understanding the nuances of Schlage LFIC systems can significantly enhance your locksmithing repertoire, allowing for more efficient and secure installations. Whether you're rekeying a commercial building or upgrading security systems, knowledge of LFIC systems is invaluable.
-
Installation Tips: Ensure you use LFIC-prepped hardware and understand the function of the control key.
-
Maintenance Advice: Regular checks on pinning integrity and core stability can prevent security breaches.
By understanding and utilizing the features of Schlage LFIC systems, you can enhance both your skills and service offerings in the locksmithing field.
