WalrusDragonOnABike [they/them]

When you have a model number or entire brands or multiple brands that are all keyed alike and sold publicly, it hardly counts as a leak. You could go to Walmart and find them there too. Even before they were called TSA keys.

Only if you use a TSA lock. And those TSA keys started as a collection of keys that were just commonly reused across locks, so people kept them around.
