I’m gonna leave this here for reference if someone wants to do the same thing I wanted to do.
The Yale Doorman V2N has a built-in NFC (Mifare Classic) reader, but it’s a bit finicky, and it requires exact cloning of the really expensive genuine Yale tags (see here for technical details). It’s annoying to use with the M1k implant in my hand. I’d rather use my easy-to-scan foot implant to open it. Not to mention, it’s easier with my hands busy with groceries.
If you want to remote-control the Yale Doorman V2N from a computer, a Raspberry Pi or an Arduino, you’ll need:
- and the following mod to the keyfob’s PCB to control it with TTL signals:
The fob only draws 30mA, so you can even power it with a healthy I/O line, provided the voltage doesn’t drop below 4.2V.
As specified in the Yale manual, to enroll the fob, B1/B2 and B3/B4 need to be depressed at the same time when the lock is waiting for a new fob to enroll. So you’ll need to take care of this in your code. Once enrolled, the lock can be opened by strobing B1 only.
I have an Arduino Uno on order for this project,
but by the time it gets here, it’ll be too late and I’ll have run out of time. So most likely this project will never be completed. But hopefully this will help you if you have a Yale Doorman V2N and you want to remote-control it too. [It’s done - see below]
