If you’re dealing with commercial locks, there’s a good chance you might come across the Schlage Large Format Interchangeable Core (LFIC) lock. Although they aren’t the most common, certain buildings are exclusively equipped with them. In this blog post, we’ll guide you through the essential steps to remove and manage Schlage LFIC locks effectively.

The Schlage LFIC is unique due to its larger format compared to small format locks and is available in various keyways, such as SC1, SC4, and even Primus C123s. While it’s a versatile and robust locking mechanism, it requires proper handling to avoid complications.

Schlage Large Format Interchangeable Core (LFIC) Overview

The Schlage Large Format Interchangeable Core (LFIC) is a widely used commercial lock system designed for convenience and security. Unlike small format interchangeable cores (SFIC), LFIC uses a unique control key system to easily remove and replace lock cores without disassembling the entire lockset.

Understanding Schlage LFIC

  • Variety of Keyways: Schlage LFIC comes in multiple keyways, including SC1, SC4, Primus, and C123, ensuring compatibility with various security setups.
  • Control Key Requirement: To remove the core, a specialized control key is necessary. This key is different from regular operating keys and features a unique notch that enables smooth removal and reinstallation of the core.
  • Zero-Bitted Blanks: When replacing cores, factory-provided control keys are typically blank and require cutting to 00000 to function correctly.

Proper Handling of Schlage LFIC

  1. Using the Control Key: Always use a factory-provided control key labeled “Control” to avoid compatibility issues.
  2. Avoid DIY Modifications: Some locksmiths attempt to modify standard keys by cutting back the shoulder and adding a notch to mimic a control key. While this may work temporarily, it is unreliable and prone to failure.
  3. Key Cutting for Rekeying: When rekeying, cut the new key to match the customer’s key or master key system. Ensure proper alignment to maintain seamless functionality.
  4. Reinstallation: To reinstall the core, align it with the lockset, insert the control key, turn, and secure it back in place.

Conclusion

The Schlage LFIC system provides a secure and efficient way to manage commercial locks. By using properly cut control keys and avoiding unreliable modifications, you can ensure smooth operation and longevity of your lock systems. The Schlage LFIC is a robust and adaptable lock system, albeit not without its peculiarities. Always ensure you have the correct control key—preferably one directly from Schlage with ‘control’ marked on it. In this way, you’ll maintain an efficient working system, ensuring seamless removal, rekeying, and reinsertion of the lock core.

To remove the core of a Schlage LFIC lock, you need a control key. This key is essential—not just any key will do. A true control key has distinct features like a specific notch on the end, vital for making the core’s removal possible. When you buy control keys, ensure they explicitly have ‘control’ inscribed on them.

The process of using a control key starts with understanding the “zero bitting” technique. Out of the factory for a replacement, keys are cut to a bitting level of zero, zero, zero. It’s crucial to ensure your control key is correctly notched and bitted at zero for optimal operation.

Avoiding Missteps with Locksmith Dealer Keys

One common issue arises when dealers attempt to economize by modifying keys. They may cut back the shoulder on keys or try to forge notches in non-factory keys, which, while feasible in emergencies, results in unreliable operations. Factory-issued control keys are consistent and dependable, unlike their makeshift counterparts.

Proper LFIC Installation and Removal

When properly equipped with a correctly bitted control key, removal and rekeying of the Schlage LFIC are straightforward. The control key enables you to turn and disengage the retainer snugly, which makes removing the core completely hassle-free.

Reinstalling or rekeying follows a standard procedure. Once rekeyed to the customer or master key, inserting it properly will secure the core, demonstrating why the correct control key is invaluable.

Beware of Non-Control Keys

While it’s possible to craft a makeshift control key in emergencies by cutting back the shoulder and adding a notch, it’s an unreliable solution. We recommend relying solely on factory-stamped keys to minimize downtime and avoid operational friction.
