Just how secure are 3D printed keys? Read on to learn more about these innovative systems, their practicalities, and their limitations.

We have to hand it to the Transportation Security Administration (TSA). They seem to have a perfect track record of screwing up – and that’s not an easy thing to accomplish if you think about it.

The most recent TSA folly seemed to practically fall into the Internet’s lap when a reporter for the The Washington Post published a hi-res picture of the entire set of TSA master keys while writing an article about how the TSA handles your bags after checking them at the counter. Well, the lock picking community when nuts and in a short time had 3D printed versions available and working. You can see it in action in the (twitter) video after the break.

For those that are not familiar with travel in the US, you are not allowed to use just any old lock on your bags. It has to be approved by the TSA – and that means that they have to be able to open it. So the TSA agents have a set of master keys that can open any bag if they need to look inside for some reason. If you put a non-TSA approved lock on the bag, that can make them a little angry, and you risk having your bag delayed or even cut open.

Of course, you can get into just about any suitcase with a ball point pen, so maybe this isn’t a real “security” issue, but it sure isn’t what you want to see from the agency that is supposed to protect you.
