What "Simplex 5031" Means in the Simplex 5000 Series

The Simplex 5000 family includes four model variants on the same chassis: 5021 (exterior combination change with key override), 5031 (interior combination change with key override), 5041 (exterior combination change with key override and passage option), and 5051 (interior combination change with key override and passage option). The 5031 specifically requires interior combination change, which means the lever release combination change tool can only be operated from the inside of the door. This is the configuration the U.S. Department of Defense requires on military and federal facility openings because it prevents combination changes from the exterior even when the door is open, eliminating a security exposure. If the spec calls for D.O.D.-compliant push button hardware, the 5031 (or 5051 with passage) is the correct model.

How the Simplex 5031 Operates

Five vandal-resistant mechanical pushbuttons (1 through 5) plus an Enter button. Anodized aluminum buttons. One combination code per lock made of any combination of one to five numbers, pressed individually or simultaneously, producing thousands of possible combinations. Press the code, turn the outside lever, latch retracts. Inside lever always retracts the latch (free egress). Mechanical key override on the outside is provided by the Schlage Large Format IC core (sold separately) for emergency access. No batteries, no wiring, no electronics. The combination change is performed from the interior using the lever release tool included with the lock.
