Commercial-grade electronic lock

The Simplex E2031LL-626 is a Grade 1 cylindrical lock with a satin chrome finish and a 2-3/4 inch backset. It serves commercial and institutional doors that are 1-3/8 to 2-1/2 inches thick. The lock provides exterior access by combination while allowing free egress at all times. It is not suited for residential buyers who want a keyed entry option or a deadbolt mechanism.

Battery-powered operation

The unit runs on batteries and requires no wiring to or through the door, so normal use adds no load to building electrical circuits. Solid cast housing and levers withstand heavy indoor and outdoor traffic without generating mechanical noise. There is no cooling fan or active thermal component to consider. It is not suited for installers who need a hardwired access-control integration.

Keypad programming and optional software

Up to 100 access codes of four to eight digits are stored and can be programmed directly at the keypad. Optional Microsoft Excel based software offers an alternative management method for larger code sets. The lock has no key bypass cylinder, so credential recovery depends entirely on code administration. It is not suited for facilities that require a physical key override for emergency entry.

Questions about this item

How do I install the 2-3/4" backset latch on a 1-3/4" door, and what step is often missed?

Drill the 2-3/4" backset hole, mount the cylindrical lock body, secure the floating face plate, and program codes at the keypad; the step often missed is verifying the 1/2" throw latch fully engages the strike before tightening all screws.

Which parts will need replacement after extended use on this Grade 1 lock?

The cylindrical drive unit and 1/2" throw latch assembly are the wear items; the solid cast levers and exterior housing are built for heavy duty cycles and rarely require service.

What is the first limit reached during continuous code entry on the E-Plex keypad?

The keypad accepts up to 100 different access codes of 4 to 8 digits; once 100 codes are stored, no further codes can be added until existing ones are deleted.
