Simplex E2031BLL-626 Satin Chrome Grade 1 E-Plex Door Lock 2-3/4" Backset 1/2" Throw SFIC Best

Grade 1 Cylindrical Lock

The Simplex E2031BLL-626 is a heavy-duty electronic push-button lock designed for commercial doors. It provides keyless exterior access by combination while allowing free egress from the interior. The unit supports up to 100 unique access codes, eliminating the expense and logistics of managing physical keys or cards. Programming is handled directly at the keypad or through optional software.

Standalone Battery Operation

Because the lock requires no wiring to or through the door, it operates independently on battery power. This design avoids the complexity and cost of hardwired installations. The solid cast housing and levers are built for extensive indoor and outdoor use, and the lock carries a fire rating for safety compliance. Performance remains consistent without reliance on building power infrastructure.

SFIC Key Override Upgrade

The lock accepts a Small Format Interchangeable Core for Best and equivalent 6 or 7 pin cores, sold separately. This feature provides a mechanical key override for facilities that require a physical backup credential. It replaces traditional key-only cylinders or older keypad locks lacking a removable core option. The upgrade is worthwhile when code management and key override flexibility are both required.
