The Professional Keyless Upgrade for Aluminum Glass Door Locks

Upgrade your security with the SK4510S（sfic), the world’s first mechanical combination keyless keypad storefront door lock designed for seamless integration and maximum reliability. Specifically engineered for storefront doors, it combines the convenience of keyless entry with the high-security standards of a professional SFIC key override.

Discription:

1: The Pain Point

Are you tired of managing metal keys for your business?

A: If you own a retail shop, office, or clinic with a standard aluminum glass door, you likely have an Adams Rite 4510S style lock. Managing keys for employees, worrying about lost sets, or paying $300 for a locksmith every time someone leaves is a headache you don't need.

B: The Solution is Here.

Upgrade to the EASILOK SK4510S（sfic)—the only keyless, mechanical keypad solution designed to drop directly into your existing door prep.

2: The Core Benefits

A: 100% Keyless Freedom: No batteries, no apps, no wiring. Just a heavy-duty mechanical keypad that works in rain, snow, or shine.

B: Drill-Free DIY Installation: Our patented axial fastening system uses the factory holes already on your door. Install it yourself in 15 minutes with just a screwdriver.

C: True Universal Handing: Whether your door swings left or right, our Non-Handed design (Reversible Keypad & Push Paddle) fits perfectly without special ordering.

3: Choose Your Security Level (SK4510 vs. SK4510S)

A: We offer two versions to fit your specific business needs:

B: SK4510 (Pure Keyless): The ultimate "No-Key" solution. No keyhole, no cylinder—maximum convenience for high-traffic employee entry.

C: SK4510S (SFIC Key Override): Features the exact same keyless functionality as the SK4510 but adds an SFIC (Small Format Interchangeable Core) Housing. This allows for a Physical Key Override, perfect for business owners who want a backup key or need to integrate the lock into a professional master-key system.
