Dormakaba 79T1611KF30 Grade 1 Heavy Duty Electronic Mortise Lockset with Clutch Mechanism, Built-in Contactless RFID Reader, Toggle Mode Lock, Concealed Key Override, Long Lever, Field Reversible, Standard No BLE

It's a mortise lockset, so the door needs a mortise pocket prepped in the edge rather than the two round bores a cylindrical lock uses. If your doors are currently prepped for a cylindrical or tubular lock, this isn't a drop-in change; you'd be cutting a new mortise pocket or replacing the door. Where a mortise case already exists from a previous mortise lock, that's the opening this suits.

It's field reversible, so one part number covers both hands. You set the handing during install instead of ordering hand-specific stock, which is what makes it practical to buy a batch for a floor of doors that swing both ways.

There's a concealed key override built into the lock, so a mechanical key gets you in when the electronics won't. It's concealed rather than face-mounted, which keeps the cylinder out of sight on the trim. For an MRO or property maintenance crew, that's the difference between a service call and a locksmith call.

Credentials are contactless RFID, read by a reader built into the lock itself, so cards or fobs present at the trim with no separate reader on the wall. This is the standard, no BLE configuration, which means no Bluetooth radio and no phone unlock. If your program depends on mobile credentials, this is the wrong version to order.

Grade 1 heavy duty, and it's a commercial lock rather than a residential one. Grade 1 is the top of the ANSI/BHMA durability tiers, which is what specs on multifamily entries, offices, dorms, and institutional corridors normally call for. If a drawing says Grade 1 mortise, this meets that line.

Toggle mode is part of this lock's operation, so a valid credential can flip the lock to a held-unlocked state and another presentation puts it back to secure. That's how you handle a classroom, a clinic suite, or a common-area door that has to stay free during the day and lock behind itself at night, without anyone walking the building twice.

The outside lever spins free when the lock is secure and only engages the latch after a valid credential. Force on a locked lever goes into the clutch instead of into the lock case, so the common failure mode on electronic trim, someone yanking a locked handle, doesn't break the mechanism. On a heavily used public door that's the part that decides how long the lock lasts.

Long lever trim, supplied in 626, satin chrome. The 79T1611KF30-626 is the single model configuration, so lever style and finish are set by the part number rather than chosen as options. Buying to match an existing floor of 626 hardware, this lines up.

The reader and the lock electronics are inside the lockset, so the credential reader isn't a separate wall device you have to run cable to. That's the point of a standalone electronic mortise lock: you get card access on an opening without pulling a hardwired reader, power supply, and door position wiring back to a panel. What you do need is a mortise-prepped door and credentials for your users.

Mortise, like the Dormakaba 79 Series, is the heavier build: the whole lock case sits in a pocket in the door edge, which supports Grade 1 duty and the concealed key override cylinder. Cylindrical electronic locks install into standard bores and are easier to retrofit onto doors that were never mortise prepped. The decision is usually made by the door you already have, not by preference: mortise-prepped doors take mortise, bored doors take cylindrical.
