Mechanical Pushbutton Lock with Key Override

The Simplex 5021XKWL-26D is a heavy-duty cylindrical lock designed for commercial doors. It provides exterior access via a single mechanical code while allowing free egress from the interior. The lock operates without batteries or wiring and includes a key override compatible with K-I-L Kaba cylinders using the Kaba 90 keyway.

ANSI/BHMA Grade 1 and Fire-Rated Performance

This lock meets ANSI/BHMA A156.2 Grade 1 standards for high-traffic durability and carries a three-hour UL/ULC fire rating for "A" label doors. The solid cast housing and levers are wear-tested for extensive indoor and outdoor use. Mechanical operation removes the ongoing maintenance requirement of battery changes.

Installation Requirements and Common Issues

The lock fits doors ranging from 1-3/8" to 2-1/4" thick with a fixed 2-3/4" backset and a 1/2" throw latch with floating faceplate. No wiring through the door is needed. Code programming is performed at the keypad without removing the lock. Installation fails when the door thickness or backset falls outside the specified range or when the existing cylinder is not a compatible K-I-L Kaba type.

Questions about this item

Should I choose the 5021 model with the Kaba 90 keyway or a different keyway for my existing K-I-L Kaba cylinders?

The 5021 model uses the Kaba 90 keyway, so it matches existing K-I-L Kaba cylinders with that same keyway for the key override function.

What does the Grade 1 rating mean for daily use on a busy office door?

The ANSI/BHMA 156.2 Grade 1 certification confirms the lock meets the highest standard for heavy-duty commercial cycle testing and abuse resistance.

How does the mechanical pushbutton interface limit code management compared to electronic locks?

The mechanical design supports a single access code programmed at the keypad without wiring or batteries, but it cannot store multiple user codes or audit trails.
