A moment’s inattention is all it takes to gather the information needed to make a physical copy of a key. It’s not necessarily an easy process, though, so if pen testing is your game, something like this Flipper Zero key copying toolchain can make the process quicker and easier when the opportunity presents itself.

Of course, we’re not advocating for any illegal here; this is just another tool for your lock-sports bag of tricks. And yes, there are plenty of other ways to accomplish this, but using a Flipper Zero to attack a strictly mechanical lock is kind of neat. The toolchain posted by [No-Lock216] starts with an app called KeyCopier, which draws a virtual key blank on the Flipper Zero screen. The app allows you to move the baseline for each pin to the proper depth, quickly recording the bitting for the key. Later, the bitting can be entered into an online app called keygen which, along with information on the brand of lock and its warding, can produce an STL file suitable for downloading and printing.

Again, there are a ton of ways to make a copy of a key if you have physical access to it, and the comments of the original Reddit post were filled with suggestions amusingly missing the entire point of this. Yes, you can get a key cut at any hardware store for a buck or two that will obviously last a lot longer than a 3D-printed copy. But if you only have a few seconds to gather the data from the key, an app like KeyCopier could be really convenient. Personally, we’d find a smartphone app handier, but if you’ve got a Flipper, why not leverage it?

Thanks to [JohnU] for the tip.

Got a Flipper Zero? Ever wanted to use a high-level but powerful scripting language on it? Thanks to [Oliver] we now have a MicroPython application for the Flipper, complete with a library for hardware and software feature support. Load it up, start it up, connect over USB, and you’ve got the ever-so-convenient REPL at your disposal. Or, upload a Python script to your Flipper and run them directly from Flipper’s UI at your convenience!

In the API docs, we’re seeing support for every single primitive you could want – GPIO (including the headers at the top, of course), a healthy library for LCD and LCD backlight control, button handling, SD card support, speaker library for producing tones, ADC and PWM, vibromotor, logging, and even infrared transmit/receive support. Hopefully, we get support for Flipper’s wireless capabilities at some point, too!

Check out the code examples, get the latest release from the Flipper app portal or GitHub, load it up, and play! Mp-flipper has existed for the better half of a year now, so it’s a pretty mature application, and it adds quite a bit to Flipper’s use cases in our world of hardware hacking.
