Several times I was at Kettleman when my car did not have the current update, so the code displayed in Nav was not the most recent and didn't work. Fortunately Tesla owners are a helpful bunch, so when they see another owner frowning and punching in the numbers (even remembering the symbol at the end) and trying the door and not getting anywhere, they assume you must be a "first timer" and helpfully explain the system while letting you inside. I mean, that's what I've heard, anyway.
Tesla, if you're reading, it would be fantastic if you could enable prox-card/tap access to lounges with Model 3/Y and new S/X key cards.
