No no. My employer is fine with me modifying the building here and there (to a point).
Our CEO actually thinks my quest to go keyless is amusing and interesting. He even let me have access to the internal security system’s webpage that displays everybody’s tags’ scan times so that I can scrape it every minute or so with a script running on the main server to open the blinds, turn the heater on, turn the lights on and turn the computer on in my office as I arrive at the main door in the morning (still working on that 
)
The problem with my office door, as with the company’s bike shed door, is that the cylinder has a master key: when someone’s not at work, the CEO must be able to get into their office. So does the fire department, and the rent-a-cop doing the rounds at night.
The other problem is, it’s an old Finnish-only Abloy lock core that’s not made anymore, and even if I could replace it, there’s no electric lock core that would fit the mortise - let alone an RFID-enabled one.
But there is one solution: it’s a quite an unusual lock core in that, like many Finnish locks, turning the key hard clockwise retracts the bolt, but turning it counterclockwise 360 degrees disables the handle. The handles turn freely and don’t actuate the bolt, and that’s how it locks. So I could simply leave it unlocked and replace both handles with this one, that engages or disengages the spindle with a mechanism contained entirely within the handle itself.
The NFC handles would essentially add a separate unlocking mechanism to the door for my use alone, maintaining the key for mere unaugmented humans who need to get into my office with the master key. Same thing with the bike shed’s door, with the added complication that it’s a profile door and there isn’t enough room for a full size handle - but I’m working on that one too.
The flaw in the slaw is, the NFC reader in the handle doesn’t wake up with implants. That’s one of the reasons why I’ll be getting a FlexM1 in a couple of months.
And no, I’m not averse to spending money on stuff for my office: I already dropped 229 euros on my locker’s NFC-enabled lock. I mean, it’s just a friggin’ locker for my dirty cycling clothes ferchrissake! And between the handles for my office door and the bike shed - assuming I get them to work for me - I’ll be looking at blowing north of 900 euros. And that’s not counting the long-range RFID reader under my desk, and the modifiied SureFlap catflap that I’ll install on the warehouse door to open it with my foot…
Incidentally, did I mention that my employer is extremely cool?
