Mechanical keyless entry lock

The Simplex 904-1-04 is a heavy-duty mechanical pushbutton combination lock finished in satin brass. It provides keyless access via a single user code programmed at the keypad without removing the unit from the door. Free egress is always available from the interior via a thumbturn.

Manual relocking and door-thickness limits

This deadbolt does not relock automatically; it must be manually relocked after each use. The lock fits doors between 1-3/4" and 2-1/8" thick and installs with a 2-9/16" backset for outswing doors or a 2-1/2" backset for inswing doors.

One-inch deadbolt with flat strike

The 1" (25mm) deadbolt engages a flat strike plate for secure latching. A cast front housing, force-resistant construction and clutch-protected thumbturn reinforce physical durability. Buyers needing automatic relocking or multiple user codes should consider other options.

Questions about this item

Which backset should I choose for my door swing?

Use the 2-9/16" backset for outswing doors and the 2-1/2" backset for inswing doors; the lock body supports both measurements.

How does the 1" deadbolt operate in daily use?

The deadbolt throws a full 1" (25mm) and must be manually relocked each time; it does not self-lock after the door closes.

What does the flat strike mean for installation?

The included flat strike mounts flush on the door frame and works with the 1" deadbolt on doors 1-3/4" to 2-1/8" thick.
