> I was driving and we left without recognizing that a few hundred dollars of keys had been lost. What do you mean by "a few hundred dollars of keys?" Do hardware stores charge more than a few dollars per key in your area? Were these private keys to a crypto wallet?
If your car has a smart key, it can be over $100 to replace and another $100 to have a dealer or locksmith re-program it. Edit, more things that are expensive: - if you live in an apartment with nfc entry, they might charge an arm and a leg to replace it, even if the actual device is only a few dollars - IDK how much it costs to replace an apartment mailbox key, but I've been warned that if you lose one they need to…
That's just theft — plain and simple. The only half valid argument I've heard is to discourage carelessness leading to loss of the key and weakening of the building security. But that's moot in places where the garage gate is broken and left open half the year (my current place) or where people can casually wait for someone to walk in and tail gate them without anyone complaining.
By the way, I purchased a proxmark a long time ago to play with and to date, it has paid for itself many times over, by allowing me to carry my building keys the way I like to (cards vs bulky key fobs) by duplicating them where otherwise it would cost $100 or impossible.
Can't wait for keys on Apple Wallet to become mainstream.
