Mechanical keyless entry for commercial doors

The Simplex 919-04 is a heavy-duty pushbutton combination lock built for doors 1-3/4" to 2-1/8" thick. It suits offices, storerooms or any interior opening where issuing physical keys is impractical. The satin brass finish resists wear in high-traffic areas. Installation requires no wiring or battery changes.

Deadlocking latch and angle strike included

The 5/8" deadlocking spring latch automatically secures the door each time it closes, preventing lock manipulation through the door gap. An angle strike is supplied in the box, so the latch engages cleanly on both inswing and outswing frames. The single access code is set at the keypad without removing the lock from the door. Free egress is always available via the interior thumbturn.

Backset choice decides fit

Outswing doors need a 2-9/16" backset; inswing doors need a 2-1/2" backset. Measure the existing bore before ordering — the lock only fits one of those two dimensions. Buyers who need a different backset or a keyed override cylinder cannot use this model.

Questions about this item

Does the mechanical pushbutton combination mechanism on the 919-04 require any batteries or scheduled lubrication?

The lock is fully mechanical and eliminates the material and labour expense of battery replacements; no power source is needed.

What stops the latch from being forced back when the door is closed under pressure?

A 5/8" deadlocking spring latch automatically relocks each time the door closes, resisting forced retraction.

How much heat or noise does the lock produce during continuous daily operation?

As a purely mechanical device with no motor or electronics, it generates no measurable heat and operates silently.
