Not All RFID Writers Work with Kyber Crystals

Get a Proxmark3 Easy and take the time to learn how to use it.
RFID passwords are in description below!

In previous videos I showed how to reprogram a kyber crystal. In this video I take a look at several handheld RFID writers and identify which ones work and which do not. Some of these writers look similar, but differences in firmware means some of them will not work with kyber crystals. I try to demonstrate how to identify the "bad" RFID writer, but newer releases of these handhelds may be emulating the 'good' writer in display, but not functionality, making it virtually impossible to find a 'good' writer anymore.

If you're interested in reprogramming kyber crystals or other RFID tags, I strongly recommend seeking out a Proxmark3 Easy which can be found on eBay and Amazon. Newer firmware for the pm3 is publicly available along with lots of instructions on how to update your PM3's firmware. See https://github.com/Proxmark/proxmark3 for more details.
