lgnore this the lock you linked previously doesn’t match this mortise lock set.
If the one you linked to is correct then a TownSteel e-genius 5000 5.5" should act as a drop in replacement. The thumb latch would be replaced with a lever, but it should work.
The e-(smart/genius/…) 5000 have a Schlage style key way (SC1 (5 pin) or SC4 (6 pin)) have a key pad for a key code, bluetooth or wifi depending on model and NFC tags. They just read the UID, so I’m using a dual frequency ring.
The Bluetooth app isn’t great, so I don’t bother with it.
You will get 2 keys, 2 NFC Stickers and 2 NFC cards with the lock.
The e-genius 5000 is $315 from CLK Supplies.
