The E-Plex is no longer made. Here is how to pick from what is left

If you run a storefront with aluminum glass doors, there is a decent chance one of them has a Kaba E-Plex pushbutton lock on it. The catalog notes that dormakaba ended production of the E-Plex 3000 and 5000 Series, and the E-Plex software, on December 31, 2025. The 3200 narrow stile lock and the 3700 prox model are named in the same end-of-production notice. The factory-pitched successor, per the listings, is the dormakaba E7900 Wireless Lock.

That does not make your lock a problem. It means replacements are now a finite supply. We still list units, and the listings are plain that availability is limited and not guaranteed, so call before you build a job around one. This article sorts the families so you order the right one the first time.

Start with the lock behind it

The E-Plex is a retrofit trim for a mortise lock already in the door. It does not replace the Adams Rite body. That means the first question is not which E-Plex, it is which Adams Rite device is in the stile. The listings split the line on exactly this.

• Deadlatch models retrofit the Adams Rite 4070, 4510, 4520, 4530, 4710, 4720, 4730, 4900 and 4920AN. The listings also say they fit the 8400 mortise exit on narrow stile doors.
• Deadbolt models retrofit the Adams Rite 1850, 1950, MS 1850S and MS 1950S.

Pop the faceplate and read the number stamped on the lock body before you do anything else. If it is a 4510, you want a deadlatch model. If it is an 1850, you want the deadbolt version. Order the wrong one and it will not work, whatever the finish.

For a refresher on what the deadlatch bodies do, our 4510 deadlatch article covers it.

What every model shares

Per the catalog, these are built for narrow stile aluminum glass doors and share these points:

• Solid cast housings, with a cast lever or thumbturn.
• Rated for indoor and outdoor use.
• Batteries in a tamper-proof base on the outside housing. No wiring through the door.
• Non-handed. Handing changes in the field.
• Door thickness 1-3/4 inches. Backset 31/32 inch minimum. Recommended minimum stile 2 inches.
• Four mounting screws.
• BHMA Grade 1 life cycle and reliability testing, a 3 year warranty, and ADA accessibility.

If your stile is under 2 inches or your door is not 1-3/4 inches thick, stop. These do not fit, and no finish or model changes that.

The 3000 series: PIN only, programmed at the keypad

The E3065MKNL-744-41 is the deadlatch version with a Kaba cylinder, in dark bronze with brass accents. Its deadbolt sibling is the E3066MKNL-744-41. They are the simplest of the lot: PIN entry, programmed through the keypad, with an optional Excel-based software package. The listing gives 300 access codes per door and a memory of 9,000 audit events.

For a single door with a handful of users, that is plenty. A small office, a shop, a dentist with eight employees. You program it at the door and walk away. The listing says the cylinder is not included, so add one to the order.

Then the key override. The 3000 series is listed with a Kaba cylinder, a Schlage override or a Best core override. The E3065BNL-744-41 is the same deadlatch lock built for a Best core override. Match the override to the keying system the building already uses, or you end up with a second key ring.

The 3200 series: software required, many more codes

The E3265MSNL-626-41 is the 3200, in satin chrome with a Schlage key override. Here the listing is different in a way that matters: the lock is programmed with required Enterprise Software, not from the keypad. It holds 3,000 access codes per door and a memory of 30,000 audit events.

So the 3200 is for a business that wants the logs. A property manager who needs to know who came in at 6 a.m., a clinic with staff turnover and a reason to keep records. If you do not own the software, or nobody will run it, this is the wrong lock. A lock that cannot be programmed is a very expensive latch.

The 3700 series: PIN, prox card or both

The E3765MSNL-626-41 adds a reader. The listing calls it a PIN/PROX lock with dual credential capability: PIN only, PROX card only, or PIN plus PROX together. It programs through the keypad with the LearnLok feature or through the optional E-Plex Enterprise Software. The listing gives 300 codes with LearnLok, 3,000 with the software, and 30,000 events with the software.

PIN plus card is the setting for a door that guards something. A pharmacy back room, a records closet. Someone has to know the code and hold the card. For an ordinary front door where staff come and go, PIN alone is easier to live with.

Which one

• One door, few users, no logs needed: 3000 series, keypad programming.
• Many users, or an audit trail you will actually read: 3200 series, and the software to go with it.
• A door that needs a card, or card plus code: 3700 series.

On finish, the listings above run in dark bronze with brass accents and in satin chrome. Several configurations are listed in both, so ask if the pairing you want is not shown.

Plan for the successor

If you are standardizing a building, think before you buy a fleet of locks that are no longer made. The listings point to the dormakaba E7900 Wireless Lock as the replacement, and say we will help cross-reference an E-Plex model to the right E7900 configuration. One or two spares for a lock already installed is a sensible buy. Twenty new doors is a moment to talk about the E7900 first.

Common questions

Is the E-Plex still being made?

No. The listings say production of the 3000 and 5000 Series ended December 31, 2025.

Will it fit my Adams Rite lock?

Deadlatch models fit the 4070, 4510, 4520, 4530, 4710, 4720, 4730, 4900 and 4920AN. Deadbolt models fit the 1850, 1950, MS 1850S and MS 1950S.

Does it need wiring?

No. The listings say the batteries sit in the outside housing and nothing runs through the door.

Do I need software?

Not for the 3000 series. The 3200 listing says Enterprise Software is required.

What replaces it?

The listings name the dormakaba E7900 Wireless Lock as the successor.
