Can't really be much worse than the default Kraft mac and cheese? Got it once from the US section in the supermarket after all the gushing over it from various americans - how can you call that stuff food?!

Somewhat amusingly, when I got my first Chameleon Ultra when it was brand new I did a simple Perl client just for playing with the slots - and made the exact same mistake with my constants.

This means I can read the unencrypted part of an arbitrary room key, get the keys from the reader, and then craft the encrypted section myself to get a full key copy, with access to the building sections with online verification as well.

Met another VingcardClassic, this time with online readers in the elevators. The key to the encrypted part looks random, but: The content of the section is a fixed ID (property ID), followed by the encryption key. Room doors don't use the key.

Interestingly enough Assa Abloy has an advisory as reaction to the Flipper Zero (which did not enable this attack, just makes it way more accessible): www.vingcard.com/documents/pr...
This particular installation is only about a year old, though, so it's rather strange they used something boken.

In case the video wasn't clear enough - that's opening my door with a key copied onto one of my business cards, which are magic ntags.
The key does have some encrypted fields - but they are not used for auth, so can be just ignored, making the copying a single tap operation.

I don't buy bondtech upgrades anymore as the assembly instructions only in video form made things at least an hour longer than it needed to be.

The Mercedes EQS can do up to about 800km, which I believe would be about 500 of your funny units (ideal conditions). Good enough for going from South of Germany to Berlin, in tests. So it's getting close to that. Might still not get more - not many drive that without breaks, and we have chargers.
